Guide to Metal Composition

Metal composition refers to the materials that make up a particular type of metal. Different metals have different compositions, which give them unique properties such as strength, ductility, and corrosion resistance. Understanding metal composition is important for selecting the right metal for a given application and for determining the appropriate welding or fabrication techniques.

Carbon Steel

Carbon steel is an alloy of iron and carbon, with other elements such as manganese and silicon often added to improve strength and toughness. The carbon content in carbon steel can range from 0.05% to 1.5%, with higher carbon content resulting in greater hardness and strength but reduced ductility.

Stainless Steel

Stainless steel is an alloy of iron, carbon, and at least 10.5% chromium. Other elements such as nickel, molybdenum, and titanium are often added to improve corrosion resistance and strength. Stainless steel is highly resistant to rust and staining, making it a popular choice for applications where durability and aesthetics are important.
