Carbon steel is an alloy consisting of iron and carbon. Several other elements are allowed in carbon steel, with low maximum percentages. These elements are manganese, with a 1.65% maximum, silicon, with a 0.60% maximum, and copper, with a 0.60% maximum. Other elements may be present in quantities too small to affect its properties.The term “carbon steel” may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels.
Carbon steel is an alloy of iron and carbon, often with other elements in small percentages that affect the properties of the final product.
A few of the most common grades of steel plates and sheets are:
A36 - a low carbon steel with good strength, formability that can be securely welded with a minimum yield strength of 36,000 PSI
A572-50 - higher strength steel with a minimum yield of 50,000 PSI and increased corrosion resistance
A516-70 - steel with a minimum tensile strength of 70,000 PSI that is generally used in pressure vessels and boilers
AR400 - abrasion resistant, quenched and tempered alloy steel with a high level of hardness, making it brittle and so it is not intended for structural applications
A588 - also known as Corten, this steel weathers well, forming a stable rust-like appearance that eliminates the need for painting
A1011 - a hot-rolled carbon steel alloy primarily used for sheets with high strength and formability
