Product Introduction

316L stainless steel added Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions; Excellent work hardening (non-magnetic). Excellent high temperature strength. 316L stainless steel is austenitic stainless steel and cannot be strengthened by heat treatment. It has good strength, plasticity, toughness, cold formability and good low temperature performance. Due to the addition of 2% Mo on the basis of Cr18Ni8, the steel has good resistance to reducing media and pitting corrosion. It has suitable corrosion resistance in various organic acids, inorganic acids, alkalis, salts and seawater. In reducing acid medium, its corrosion resistance is much better than 304
