Duplex Stainless Steel (DSS) refers to about 50% of ferrite and austenite, and generally requires less than 30% of stainless steel. In the case of a lower C content, the Cr content is between 18% and 28%, and the Ni content is between 3% and 10%. Some steels also contain alloying elements such as Mo

Stainless steel fasteners will lock up during use. The locking phenomenon has its own objective factors. Because stainless steel and carbon steel have inherent differences, stainless steel has good ductility, but the hardness has a certain gap with carbon steel. Stainless steel bolts and nuts will p
