ASTM A588 Grade K low alloy high strength steel

A588 Grade K, the atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition.

A588 low alloy high strength steel quality grade description: A588 Gr.A, A588 Gr.B, A588 Gr.K

We has much experience for exporting A588 Grade K and also supply our customers in supplementary requirement in S2, S3, S5, S6, S8, S15, S18, S30 and so on.

If you could need the equal steel grade with A588 Grade, you could choose the 09CuPCrNi-A, 09CuPCrNi-B,05CuPCrNi,S355J0WP,S355J2WP,Corten A, Corten B Grade steel.

A588 Grade K steel Chemical composition in Product analysis:

Carbon, %	Manganese, %	Cr %	Silicon %	N % max	Sulfur %
Max 0.17	0.50-1.20	0.40-0.70	0.25-0.50	0.010	0.05
