A572-50 channel is a HSLA columbium-vanadium steel with a higher yield and tensile strength as compared to ASTM A-36 channel. These stronger steels permit the reduction of section thickness and weight, providing added payload capacity in transportation applications as well as material cost savings. ASTM A-572 Grade 50 channel is weldable, formable, and machinable when using appropriate techniques.
A572-50 channel is used in bridges, buildings, construction equipment, freight cars, machinery, truck parts, and other applications.
Typical Mechanical Properties
For Grade 50, the minimum yield point is 50,000 psi and the minimum tensile strength is 65,000 psi. ASTM A-572 is also available in grades 42, 55, 60 and 65.
