ASTM A572/A572M Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel

ASTM A572/A572M Specification covers the standard requirements for Grades 42 [290], 50 [345], 55 [380], 60 [415], and 65 [450] of high-strength low-alloy columbium-vanadium structural steel shapes, plates, sheet piling, and bars for applications in bolted, welded, and riveted structures in bridges and buildings. ASTM A572/A572M Standard main steel grade:ASTM a572 grade 42,50,55,60,65 (A572GR42, A572GR50, A572GR55, A572GR60, A572 GRADE 65).

A572Gr, high-strength low-alloy yttrium-vanadium structural steel plates, which can be produced by domestic steel mills, are implemented in accordance with ASTM A572/A572M.

Folding specifications of ASTM A572 GR

it is 8-300mm thickness and can be fixed length and fixed width.

Usage of ASTM A572 GR

8 ~ 300mm thick A572Gr50 low-alloy high-strength structural steel plate is widely used in engineering structures, such as construction steel structures, construction machinery, mining mountainous machinery, trucks, bridges, pressure vessels, etc., especially for the requirements of better Weldability and toughness of construction and engineering machinery components. Being exported to South Korea, Taiwan and other places, the cumulative export volume has reached more than 10,000 tons.
