What is the typical carbon content in ASTM A36 angle steel

ASTM A36 angle steel generally contains 0.25-0.29% carbon.This moderate carbon level balances strength and weldability, making it suitable for structural applications. Higher carbon would increase hardness but reduce ductility, while lower levels might compromise tensile strength. The carbon content is strictly controlled during production to ensure compliance with the standard's mechanical property requirements, such as a minimum tensile strength of 400-550 MPa.
