American standard A588GrC structural steel plate Composition properties and application

1. A588GrC introduction:

A588GrC steel plate is a high weathering bridge structural steel plate, which belongs to the American standard steel plate and implements the American standard ASTM standard. When the A588GrC steel plate is rolled, a protective layer is formed on the surface of the metal matrix through the alloying of Cu, P, Cr, N, etc., so that the A588GrB steel plate has high atmospheric corrosion resistance. The same series of steel grades are: A588GrA, A588GrC, A588GrK.

2. Atmospheric corrosion resistant steel:

The steel with added copper, phosphorus, chromium, nickel and other elements to improve the resistance to atmospheric corrosion. This type of steel is divided into high weathering steel and weathering steel for welded structures.

3. A588GrC implementation standard: implement ASTM, ASME American Society for Testing and Materials standards.

4. A588GrC delivery status:

Delivery status: hot-rolled, normalized, tempered, normalized + tempered, quenched and tempered; different delivery statuses can be selected according to different needs, and the specific delivery status should be indicated in the contract.
