Stainless Steel 316 is an austenitic stainless steel alloy that has excellent corrosion resistance, particularly in aggressive environments. In comparison to regular stainless steel, the 316-grade alloy has a content of molybdenum that gives it an improved resistance to chloride-induced corrosion and is thus well-suited for marine, chemical, and industrial environments. https://www.globalsteelindustries.com/stainless-steel-316-flanges-manufacturers-suppliers-stockists-exporters.html
