Important knowledge about ASTM A572 Grade 50 steel

Posted:2021-10-19 09:16:42

ASTM A572 Grade 50 steel belongs to the high-tension low-alloy steel in the ASTM standard. ASTM A572 Grade 50 steel can also be called high-stretch low-alloy Ni-V steel, which has significant advantages in strength, weldability, and toughness. There are four steel grades in the standard ASTM A572. They are ASTM A572 GR42 (290), A572 GR50 (345), A572 GR60 (415), A572 GR65 (450).

ASTM A572 Grade 50 steel is a high-strength, low-alloy steel that finds the best application where more strength per unit weight is needed. Compared with ordinary carbon steel, fewer materials are required to meet specific strength requirements. When the steel plates are riveted, bolted or welded, ASTM A572 Grade 50 steel is used for general plate applications. ASTM A572 Grade 50 steel is a titanium-Vanadim steel that provides a minimum output of 50,000 PSI. In addition, ASTM A572 Grade 50 steel is known for its increased resistance to atmospheric corrosion. ASTM A572 Grade 50 steel has more alloying elements than ordinary carbon steel, so it is more difficult to form. ASTM A572 Grade 50 steel is more difficult to cold work, but can be successfully bent or shaped but requires more force than plain carbon steel.

Grade C≤ Mn≤ P≤ S≤ Si≤ Cu≤
ASTM A572 Grade 50 0.23 1.35 0.040 0.05 0.4 0.2

ASTM A572 Grade 50 steel can be used to manufacture buildings, bridges, equipment machinery, truck parts, transmission towers, towers and freight cars. Compared with ASTM A36 steel, the yield and tensile strength of ASTM A572 Grade 50 steel are higher.
