Overview
What Is Carbon Steel
Carbon steel is mostly made of iron and carbon. It has between 0.05% and 2.1% carbon by weight. The American Iron and Steel Institute says carbon steel does not need a set amount of alloying elements like chromium, nickel, or molybdenum. It only has small amounts of manganese, silicon, and copper. This makes carbon steel different from alloy steels. People use carbon steel because it is strong, not expensive, and easy to shape and weld.
Steel Classification
Steel can be grouped by how much carbon it has and what other elements are in it. The main types are low-carbon, medium-carbon, high-carbon, and ultra-high-carbon steel. Each type has its own features and uses. The table below shows the main types and what they are like:
Type | Carbon Content Range (%) | Typical Alloying Elements and Limits | Typical Applications and Notes |
---|---|---|---|
Low-Carbon Steel | Up to 0.30 | Up to 0.4% manganese; other elements limited | Used in automobile body panels, tin plates, wire products; easy to form |
Medium-Carbon Steel | 0.30 to 0.60 | Manganese 0.60% to 1.65% | Used for shafts, axles, gears, forgings, rails; can be quenched and tempered |
High-Carbon Steel | 0.60 to 1.00 | Manganese 0.30% to 0.90% | Used for springs, high-strength wires |
Ultrahigh-Carbon Steel | 1.25 to 2.00 | Experimental alloys with special processing | Used for knives, axles, punches |
You can see the carbon content range for each type in the chart below:

Low-carbon steel is the most common type. It makes up over 90% of the market’s revenue in 2024. This is because low-carbon steel costs less and is easy to shape and weld. Medium and high-carbon steels are used when you need more strength or better wear resistance.
Usage
Steel is used in many industries. You can change its properties by changing the carbon content. The main uses of carbon steel are:
- Construction: Steel is used for beams, columns, and other parts.
- Automotive: It is used for body panels, chassis, and engine mounts.
- Machinery: Steel is used for gears, shafts, and bearings.
- Pipes and Tubes: It is used for oil and gas, water treatment, and chemical plants.
- Appliances: Steel is used for casings, frames, and other parts.
steel is used in many products. The global market for steel was USD 1,017.52 billion in 2024. Low-carbon steel is used the most because it is needed in construction, cars, and ships. Asia Pacific is the biggest market, then North America and Europe.
Tip: Pick the right steel by matching its features to what you need. This helps you get the best results and save money.
Melting point
When you pick steel, you need to know its melting point. The melting point changes with the amount of carbon and other elements. If you add more carbon, the melting point usually goes down. Some elements like chromium and nickel can make the melting point higher. Impurities such as sulfur and phosphorus make it lower.
Here is a table that shows melting points for different steels:
Type | Example Grades | Melting Point Range (°C) | Explanation of Variation |
---|---|---|---|
Low Carbon Steel | 1018, 1020, 1030, 1040 | 1420 - 1465 | Less carbon means higher melting points. |
Medium Carbon Steel | 1065, 1080, 1095 | 1420 - 1465 | More carbon changes melting point a little. |
High Carbon Steel | (not specified) | 1425 - 1540 | More carbon gives a wider melting range. |
Alloy Steels | 4140, 4150, 4340, 8620 | 1450 - 1500 | Alloying elements can make melting points higher. |
Most steels melt between 1420°C and 1540°C. Low and medium carbon steels melt from 1420°C to 1465°C. High carbon steel can melt at higher or wider ranges. If there are more impurities, the melting point drops and quality gets worse. Always check the grade and what is in the steel before you use it.
Note: The melting point affects how you cut, weld, or shape steel. Pick the right steel grade for your needs.
Steel Density
You also need to think about the density of steel. Density tells you how heavy something is for its size. Most steels have almost the same density. Small changes in carbon make a small difference.
Here is a table with typical density values for carbon steel:
Type | Density (kg/m³) | Density (g/cm³) | Density (lb/in³) |
---|---|---|---|
Low Carbon Steel | ~7850 | ~7.85 | ~0.284 |
Medium Carbon Steel | ~7830 | ~7.83 | ~0.283 |
High Carbon Steel | ~7810 | ~7.81 | ~0.282 |
You can see that density stays almost the same for all types. The small drop in density does not change how you use carbon steel. Use these numbers to figure out weight, shipping, and building needs.
- Low-carbon steel density: about 0.284 lb/in³
- Medium-carbon steel density: about 0.283 lb/in³
- High-carbon steel density: about 0.282 lb/in³
Chemical element composition
You must check what elements are in steel before you choose it. The main parts are iron and carbon. There are also small amounts of manganese, phosphorus, sulfur, silicon, and sometimes copper, chromium, or nickel. These elements change how strong and hard the steel is.
Here is a table that shows the usual chemical makeup of carbon steel:
Element | Typical Range (%) | Purpose/Effect |
---|---|---|
Carbon | 0.05 – 2.1 | Makes steel stronger and harder |
Manganese | 0.30 – 1.65 | Makes steel stronger and easier to harden |
Phosphorus | ≤ 0.04 | Makes steel stronger, but less bendy |
Sulfur | ≤ 0.05 | Makes steel easier to machine, but less tough |
Silicon | ≤ 0.60 | Makes steel stronger |
Copper | ≤ 0.60 | Helps steel resist rust |
Chromium | ≤ 0.40 | Makes steel harder and wear less |
Nickel | ≤ 0.40 | Makes steel tougher |
Molybdenum | ≤ 0.10 | Makes steel strong at high heat |
steel grades must follow strict rules for these elements. The amount of carbon decides if it is low, medium, or high carbon steel. Other elements stay in small amounts to keep the steel good. Always check the chemical makeup to make sure the steel is right for your job.
Yield and Tensile Strength
When you select steel for your project, you need to understand yield strength and tensile strength. These two properties help you decide if a material will work for your application. Yield strength tells you the point where steel starts to bend or change shape. Tensile strength shows you the maximum force carbon steel can handle before it breaks.
You will find that different grades of steel have different strength values. The carbon content and the way you process the steel affect these numbers. For example, low carbon steel has lower yield and tensile strength. High carbon steel has higher values. You can see the differences in the table below:
Steel Grade Category | Tensile Strength Range (MPa) | Yield Strength Range (MPa) |
---|---|---|
Low Carbon Steel | 400 – 550 | 250 – 350 |
Medium Carbon Steel | 600 – 800 | 400 – 500 |
High Carbon Steel | 900 – 1,200 | 550 – 700 |
You can also look at specific grades of steel. Each grade has its own strength range. The table below shows some common grades and their properties:
Grade | Condition | Tensile Strength (MPa) | Yield Strength (MPa) |
---|---|---|---|
ASTM A36 | Hot Rolled | 400 – 550 | 250 |
SAE 1018 | Cold Drawn | 440 – 640 | 370 |
SAE 1045 | Normalized | 620 – 790 | 415 |
SAE 4140 | Quenched + Tempered | 950 – 1,100 | 850 |
SAE 1095 | Quenched + Tempered | 990 – 1,220 | N/A |
You should match the strength of steel to your needs. If you need to form or bend parts, you may want low carbon steel. If you need to make tools or springs, you may need high carbon steel. The way you treat carbon steel, such as quenching or tempering, can also change its strength.
Note: Always check the grade and treatment of carbon steel before you use it. This helps you avoid problems in your production.
You can use steel in many industries. For example, you can use SAE 1045 for gears and shafts. You can use SAE 4140 for axles and landing gear. You can use ASTM A36 for beams and plates. Each application needs a different balance of yield and tensile strength.
When you choose carbon steel, you make sure your parts will not fail under load. You also make sure your parts will last as long as you need. You can talk to engineers or suppliers to help you pick the right carbon steel for your job.
Low Carbon Steel

Advantages Of Low Carbon

Wear Resistance
Low-carbon steel wears out faster in tough places. Moving parts or tools may break sooner if you use it. You might have to replace these parts more often.
Corrosion
Low-carbon steel can rust if you do not protect it. You can use coatings like galvanizing to help stop rust. These coatings cost extra but help the steel last longer.
Note: Think about the good and bad sides of low-carbon steel before you pick it. It is cheap and easy to use, but it is not as strong or tough. Knowing both sides helps you choose the best material for your job.
Medium Carbon Steel
Advantages Of Medium Carbon
Strength
Medium-carbon steel is strong. It has 0.30% to 0.60% carbon. This makes it stronger and harder than low-carbon steel. Its tensile strength can be from 400 to 2730 MPa. The strength depends on how you treat the steel. You can use it for parts that carry heavy loads. It is good for things that get hit or pushed hard. Axles, gears, and crankshafts use this steel. It does not bend or break easily.
Ductility
Medium-carbon steel is strong but still bendy. You can shape it without breaking it. This helps when you need parts that take in energy. It is good for fasteners and railway parts. Machine parts also use it. The steel does not crack much when you form or forge it.
Versatility
You can use medium-carbon steel in many ways. It works for cars, buildings, and machines. You can cut or drill it with normal tools. You can also tap it for special parts. It is good for small or big jobs. You get both strength and easy work with this steel.

Tip: Use heat treatment to make medium-carbon steel work best for tough jobs.
Disadvantages Of Medium Carbon
Weldability
Medium-carbon steel is harder to weld. More carbon makes welding tricky. You might get cracks or weak spots if you are not careful. You need special welding ways and must check the steel mix. Tests like X-ray fluorescence help you find problems.
Cost
Medium-carbon steel costs more than low-carbon steel. More carbon and other elements raise the price. You also pay more for heat treatment and checks. This can make your project cost more.
Workability
Medium-carbon steel is not as easy to shape. It is more brittle, so it is harder to form. You may need stronger tools or more force. If you do not handle it right, it can crack or have flaws.
Corrosion
Medium-carbon steel can rust if not protected. It does not fight rust as well as some metals. You need coatings or treatments to stop rust. You also need to check and care for it often.
Aspect | Details |
---|---|
Brittleness | Medium-carbon steel is more brittle than some metals. If you do not heat-treat it right, it is even harder to shape. |
Weldability | It melts at a good point for welding, but its brittleness can make welding harder. |
Rusting | It rusts easily, so it may not last as long without care. |
Cost | It costs more than low-carbon steel because of extra elements. |
Comparison | It is more brittle than low-carbon steel but less brittle than high-carbon steel. |
Note: Think about the good and bad sides before you pick medium-carbon steel. It is strong and useful, but you must watch out for welding, cost, and rust.
High Carbon Steel
Advantages Of High Carbon
Strength
You get high strength when you choose high-carbon steel. The steel forms martensite during heat treatment, which increases its strength. When you temper the steel, you create tempered martensite with finely dispersed carbides. This structure helps the steel handle heavy loads and high stress. You can use high-carbon steel for parts that need to stay strong under pressure, such as cutting tools and springs.
Hardness
High-carbon steel gives you high hardness. When you anneal the steel for longer times, larger carbide particles form. These carbides make the steel harder. Rockwell hardness tests show that samples annealed for 8 or 12 hours have higher hardness than those annealed for 4 hours. You can rely on this hardness for applications that need sharp edges or resistance to deformation.
Wear Resistance
You benefit from excellent wear resistance with high-carbon steel. The microstructure contains ferrite and cementite in plate-like shapes. This structure resists abrasive wear. In high-carbon Cr-V alloy steel, carbon combines with chromium and vanadium to form stable carbides. These carbides create a hard phase that reduces wear. When you use high-carbon steel for gears or blades, you get longer service life and less maintenance.
Tool Use
You often see high-carbon steel in tools. The steel’s hardness and wear resistance make it ideal for cutting, shaping, and drilling. You can use it for knives, saw blades, chisels, and dies. The steel holds a sharp edge and resists dulling. Many industries depend on high-carbon steel for reliable tool performance.
Tip: Use high-carbon steel when you need parts that must stay sharp, hard, and strong during tough jobs.
Disadvantages Of High Carbon
Brittleness
High-carbon steel has high strength but low ductility. When you increase the martensite content, the steel becomes more brittle. X-ray diffraction and electron back-scatter diffraction studies show that more martensite leads to less bending before breaking. You need to watch for sudden failure in parts that face impact or shock.
Machinability
You may find high-carbon steel harder to machine. The high hardness wears down cutting tools quickly. You need special equipment and slower speeds to cut or shape the steel. This can slow down your production and increase tool costs.
Weldability
High-carbon steel does not weld easily. The high carbon content causes cracks during welding. You need to use special welding techniques and preheat the steel to reduce the risk of cracking. Even with care, welding high-carbon steel takes more time and skill.
Cost
You pay more for high-carbon steel than for low or medium-carbon types. The extra processing, heat treatment, and tool wear add to the cost. You need to balance the pros and cons when you select high-carbon steel for your project.
Note: High-carbon steel gives you strength, hardness, and wear resistance, but you must manage brittleness, machinability, weldability, and cost.
Carbon Steel Selection Guide Industrial
Application Matching
You need to match the right steel to your project. The steel selection guide industrial helps you do this by focusing on your needs. Start by looking at what your part must do. If you need high strength and durability, you may want a medium or high-carbon steel. If you need easy shaping and welding, low-carbon steel works best.
- Define your performance needs. Use steel for easy fabrication and workability. Choose alloy steel if you need more strength.
- Check the environment. Steel fits dry, controlled spaces. If you face moisture or chemicals, use coatings or pick another material.
- Look at strength and weldability. Low-carbon steel welds easily. High-carbon steel needs special welding steps.
- Match the steel to your application. Use carbon steel for pipes, beams, and machine parts. Use alloy steel for aerospace or power plants.
- Follow best practices. Set your stress, temperature, and corrosion needs. Talk to experts. Think about long-term costs.
Tip: Always match the steel’s properties to your job. This helps you avoid problems and saves money.
You also need to think about welding. Pick filler metals that match the strength of your base steel. If you weld different steels, use filler that fits the weaker one. This keeps your welds strong and safe.
Trade-Offs
You face trade-offs when you pick a steel type. The carbon steel selection guide industrial shows you how to balance cost, machinability, and performance.
- Free machining carbon steel cuts faster and saves money. It wears tools less and gives a smooth finish. You get more parts in less time.
- Additives like sulfur help with machining but lower ductility and weldability. You must check if these changes fit your needs.
- Free machining steel works well for high-volume jobs. It costs less but does not last as long in tough spots.
- Some companies switched to lead-free free-cutting steel and saved money. They also made more parts with less tool wear.
- Use the right tools and speeds. This keeps your machines running well and your parts looking good.
- Heat treatments like annealing and case hardening change the steel’s properties. Additives can change how these treatments work.
- Watch for rules about lead in steel. Some places do not allow it.
You must also weigh cost against performance. For example, 1018 carbon steel costs less and machines well. 4140 alloy steel gives more strength but costs more and is harder to cut. Stainless steel resists rust but costs the most and is hard to machine.
Research shows that plain carbon steels can match the strength and toughness of more complex steels after heat treatment. You get good performance and save money by using simpler steels. You also avoid problems like brittle phases that come with complex alloys.
Microstructure matters too. Heat treatment changes how carbon steel resists rust. You can control grain size to get the right balance of strength and corrosion resistance. Phosphorus in steel raises strength but can make the steel crack. Keep phosphorus low to avoid problems.
