A 588 Gr B chemical composition, A 588 Gr B mechanical property
A588 Gr B is a kind of high corrosion resistant steel, under ASTM standard.
A 588 Gr B chemical composition %:
C: max 0.20; Mn: 0.75-1.35; Cr: 0.40-0.70; Si: 0.15-0.50; N: max 0.010; S: 0.050;
Cu: 0.25-0.40; P: 0.040; V: 0.01-0.10; Ni: max 0.50; other:---
A588 Gr B 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.
