A588 GrA weathering structural steel composition and application

Basic information of A588 GrA weathering structural steel:
Grade A588, under standard ASTM A588/A588M, is atmospheric corrosion resistant high strength low alloy structural steel with a minimum yield point of 345MPa.

Chemical composition of A588 GrA weathering steel plate:
C≤0.19, Si: 0.3-0.65, Mn: 0.8-1.25, P≤0.03, S≤0.03, Ni≤0.4, Cr: 0.4-0.65, Cu: 0.25-0.4, V: 0.02-0.1

Application scenarios of A588 GrA steel plate:
A protective layer is formed on the surface of the metal substrate, so that it has high atmospheric corrosion resistance. A588 low-alloy high-strength steel plates include A588 GrA, A588 GrB, A588 GrC, which are used for manufacturing workshops, general buildings and various construction machinery, such as mines and various drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts for engineering construction.
