Grade 60 Steel: Chemical Properties

Grade 60 steel is a general-purpose carbon steel known for its balance of strength and ductility. Its chemical composition typically includes the following elements:

Key Chemical Properties of Grade 60 Steel

• Carbon Content: The higher carbon content compared to mild steel (typically 0.20-0.30% C) gives Grade 60 steel increased strength but reduces ductility.
• Manganese Content: Manganese improves the steel’s hardenability, meaning it can be heat-treated to achieve a desired hardness.
• Phosphorus and Sulfur: These elements are kept to low levels to prevent brittleness.
• Silicon Content: Silicon helps to deoxidize the steel during its production process.

Additional Properties

• Hardness: Grade 60 steel can be heat-treated to achieve a hardness ranging from Brinell 120 to 200, depending on the specific heat treatment process.
