Carbon Steel - Definition, Types, Grades, Benifits, Applications Full Overview
Carbon steel is a versatile material that is widely used in metal fabrication due to its strength, affordability, and ease of fabrication.
What's Carbon Steel?
Carbon steel is a type of steel that primarily consists of carbon as the main alloying element, with small amounts of other elements such as manganese, silicon, and copper. The carbon content in carbon steel can vary from 0.05% to 2.0%, and the higher the carbon content, the harder and stronger the steel will be.
Carbon steel is widely used in various industries because of its strength, durability, and affordability. It is commonly used in the production of construction materials, automotive parts, machinery, tools, and knives. Carbon steel can also be easily machined, welded, and formed into various shapes and sizes.
However, carbon steel is susceptible to rusting and corrosion and requires regular maintenance and protection to prevent it from deteriorating. To prevent rust and corrosion, carbon steel is often coated with a layer of protective material, such as paint, oil, or galvanizing.
Types of Carbon Steel
There are four main types of carbon steel, based on the carbon content and other alloying elements present:
Low-carbon steel: Also known as mild steel, low-carbon steel contains a relatively low percentage of carbon (typically less than 0.30%) and small amounts of other elements. It is easy to form, weld, and machine, and is commonly used in construction, automotive, and other general applications.
Medium carbon steel: Medium carbon steel contains a higher percentage of carbon (between 0.30% and 0.60%) and may also contain small amounts of other elements such as manganese, silicon, and phosphorus. It has higher strength and hardness than low carbon steel, but is also more difficult to form and weld. It is commonly used in applications such as forging, axles, and machinery parts.
High carbon steel: High carbon steel contains a higher percentage of carbon (between 0.60% and 1.4%) and may also contain small amounts of other elements such as manganese, silicon, and vanadium. It has the highest strength and hardness of all types of carbon steel, but is also the most brittle and difficult to form and weld. It is commonly used in applications such as knives, cutting tools, and springs.
Very high carbon steel: Very high carbon steel contains a very high percentage of carbon (between 1.5% and 2.0%) and may also contain small amounts of other elements such as manganese, silicon, and vanadium. It has extremely high strength and hardness, but is also extremely brittle and difficult to form and weld. It is used in specialized applications such as springs and high-strength wire.
Grades of Carbon Steel
There are many different grades of carbon steel, which vary in their composition, properties, and intended applications. Some common grades of carbon steel include:
ASTM A36: This is a low-carbon steel grade that is commonly used in structural applications, such as building construction and bridge building.

ASTM A500: This is a cold-formed welded and seamless carbon steel structural tubing grade that is commonly used in construction, transportation, and industrial applications.
ASTM A516: This is a pressure vessel quality carbon steel plate grade that is commonly used in moderate and lower temperature service.
ASTM A572: This is a high-strength low-alloy carbon steel grade that is commonly used in structural applications, such as building construction and bridge building.
ASTM A588: This is a high-strength low-alloy carbon steel grade that is commonly used in structural and architectural applications, such as bridges and buildings.
ASTM A1011: This is a hot-rolled steel sheet and strip commercial quality carbon steel grade that is commonly used in automotive, construction, and other applications.
ASTM A105: This is a carbon steel forging grade that is commonly used in piping applications.
ASTM A234: This is a carbon steel pipe fittings grade that is commonly used in high-pressure and high-temperature applications, such as oil and gas processing plants.
There are many other carbon steel grades available, and the selection of a specific grade will depend on the intended use and performance requirements.
