A588GrK steel plate sheet Chemical composition

1. Introduction of A588GrK steel plate

A588GrK steel is a high-strength low-alloy structural steel suitable for welding, riveting or bolting, mainly used for welding bridges and buildings, where it is very important to reduce weight or increase durability. In most environments, the atmospheric corrosion resistance of this steel is significantly better than that of carbon structural steel with or without copper added.

2. A588GrK steel plate implementation standard: ASTM A588/A588M

3. Delivery status of A588GrK steel plate: hot rolled, normalized, tempered, normalized + tempered, quenched and tempered. Different delivery states can be selected according to different needs.

4. Chemical composition of A588GrK steel plate

Grade CMnPSSiNiCrCuMoNbA588GrK≤0.170.50-1.20≤0.030≤0.0300.25-0.50≤0.400.40-0.700.30-0.50≤0.100.005-0.05

Remarks: For every 0.01% decrease under the specified large carbon (C), the specified manganese (Mn) is allowed to increase by 0.06%, and the manganese (Mn) content is 1.50%. For A588GrK steel plates with a thickness of less than 13mm, the niobium content is not required.
