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.


  • Depths: 0.5"  to 18";     Flange Widths: 0.125" to 5"

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.
