ASTM A572 Gr 50 VS A36 steel

ASTM A572 Gr 50 VS A36 steel

Basically ASTM A572 Gr 50 is high strength, low alloy Columbium-Vanadium structural steel. ASTM A36 steel is just a common low carbon steel. Both chemical composition and mechanical properties of ASTM A572 Gr 50 and A36 steel differ much with each other.

ASTM A572 Gr 50 VS A36 steel in chemical composition:

Item C Mn P S Si Cu
A572 Gr 50 ≦0.26 ≦1.65 ≦0.040 ≦0.050 ≦0.40  -
A36 ≦0.26 - ≦0.040 ≦0.050 ≦0.40 ≧0.20
