A 588 Gr A chemical details,A 588 Gr A mechanical properties

A588 Gr A steel is a kind of high corrosion resistant steel, under ASTM standard. Equal steel grade of ASTM A588 Grade A, in other standards: EN 10155 :S355J2G1W;SEW 087:WTSt 52-3; UNI:Fe510 D2K1;BS 4360:WR 50 C and some other steel grade.

A 588 Gr A chemical composition , A 588 Gr A chemical details:
C: max 0.19; Mn: 0.80-1.25; Cr: 0.40-0.65; Si: 0.30-0.65; N: max 0.010; S: 0.040;
Cu: 0.25-0.40; P: 0.05; Ni: 0.40; other:---
A588 Gr A steel plate, this kind of steel is not easy to rust. when steel plate were exposed in the atmosphere, Cu and P were combined into a dense layer of Oxidation film, and Cr and Ni also can make an Oxidation film, so the kind of steel has a very good corrosion resistant.
