Introduction to 316 Stainless Steel Pipe

What is 316 Stainless Steel?

316 stainless steel is austenitic stainless steel alloy primarily composed of iron, with significant amounts of chromium (16-18%), nickel (10-14%), molybdenum (2-3%), and small quantities of other elements. The addition of molybdenum enhances corrosion resistance, especially against chlorides and marine environments.
