High Strength, Low Alloy ASTM A572 Steel Sheet, Plate, and Beam

Alro stocks ASTM A572, a high strength, low alloy steel plate that offers an optimum combination of strength, weldability and notch toughness with economy. ASTM A572's Post-weld heat treatment may degrade heat-affected zone strength and toughness. Pretesting of specific welding and post-weld heat-treating procedures is recommended to assure optimization of final property levels.

ASTM A572 is a high strength, low alloy steel plate. It offers an optimum combination of strength, wearability, and notch toughness. Applications include bridges, buildings, automotive and truck parts, railroad cars, cargo containers, tote boxes, construction equipment, structural tubing, lighting standards, and transmission poles.
