ASME SA588 Grade A High Tensile Tough Plate

High Strength Low Alloy HSLA Steel Products Description

SA588GrA high strength steel plate is a high strength low alloy structural steel plate with atmospheric corrosion resistance, SA588GrA high strength low alloy steel plate standard specifies that the yield strength of SA588GrA low alloy steel plate is 345MPa. 345MPa.

SA588GrA high strength plate can be used for welding, engineering machinery, riveted and bolted structures, but it is mainly used for welded bridges and buildings that require reduced weight or extended life.

In addition, SA588GrA high tensile alloy steel has significantly better atmospheric corrosion resistance than carbon structural steel with or without copper under most environmental conditions.
