A572Gr is divided into five grades: 42 (290) grade, 50 (345) grade, 55 (380) grade.
A572Gr50g steel plate is suitable for riveted, bolted or welded structural parts, and grades 60 (415) and 65 (450) are used for bridge riveted and bolted structural parts or welded structural parts for other purposes.
A572Gr50 steel plate executive standard executive standard: ASTM A572/A572M.
A572Gr50 steel plate has a thickness of 8-300mm, and can be rolled at a fixed length and width.
A572Gr50 low-alloy high-strength structural steel plates with a thickness of 8-300mm are widely used in engineering structures, such as building steel structures, construction machinery, mining machinery, trucks, bridges, pressure vessels, etc., especially for those requiring good weldability. and toughness of building and construction machinery components.
A572Gr50 steel plate is normalized and delivered for the second inspection, which can mainly produce extra-wide and extra-thick steel plates.
