High strength A572 Gr 55 low alloy steel plate sheet

A572 Gr 55 low alloy steel plate sheet is high strength structural steel that offers an optimum combination of strength, weldability and notch toughness. It is a common choice for A572 Gr 55 structural steel in the construction of bridges, buildings, and construction equipment.

The post-weld heat treatment of A572 Gr 55 steel may degrade head-affected zone strength and toughness. The structural steel A572 Gr 55 offers lower weight, higher yield and tensile strength than the comparable A36 plate.
