ASTM A572-50 carbon-low alloy steel applications

Posted:2015-11-30 22:04:03

ASTM A572-50 is a carbon-low alloy steel with a low weight, high tensile strength and yield strength, good ductility and easy to weld. ASTM A572-50 contains a variety of alloying elements so that it has a better corrosion resistance. ASTM A572-50 can be used for bridge plate, gussets, floor, structural steel and other supporting materials.
