A572M Grade 380 High-Strength Low-Alloy Structural Plates
A572M Grade 380 is a high strength low alloy niobium-vanadium structural steel plate. It is widely used in building steel structures, construction machinery and other steel structures.
Specifically, A572M Grade 380 steel plates are divided into five grades:
Grade 42 (290): Suitable for riveting, bolting or welding structural parts.
Grade 50 (345): Suitable for riveting, bolting or welding structural parts.
Grade 55 (380): Suitable for riveting, bolting or welding structural parts.
Class 60 (415): used for bridge riveting and bolting structural parts or welded structural parts for other purposes.
Class 65 (450): used for bridge riveting and bolting structural parts or welded structural parts for other purposes.
