S201 309 Stainless Steel Plate 202 2mm Stainless Steel Sheet For Building Material
S201 309 Stainless Steel Plate 202 2mm Stainless Steel Sheet For Building Material
1. Introduction
201 Stainless steel has the characteristics of polishing, no bubbles, no pinholes, etc., is the production of a variety of watchcase, watchband cover quality material.
202 stainless steel plate belongs to metastable Austenitic stainless steel system, with high strength, toughness, high wear resistance and has a large work hardening.
309 stainless steel. Stainless steel --S30908(AISI, ASTM) 309S. Steel production is more 309S stainless steel, corrosion resistance, high temperature resistance is good. It can withstand high temperature of 980°C. Mainly used in boiler, chemical industry and so on. Compared with 309S, 309 has no sulfur S content.
