316 / 316L Stainless Steel Bar
Stellanox Steel supplies top-grade 316 / 316L Stainless Steel Bars, designed for superior performance in highly corrosive and chloride-rich environments. Known for its exceptional resistance to pitting and crevice corrosion due to its molybdenum content, 316 / 316L bars are widely used in marine, pharmaceutical, food processing, and chemical industries.
Available in round, square, hex, and flat bar forms, this alloy delivers reliability, strength, and excellent machinability for critical industrial applications.
What is 316 / 316L Stainless Steel Bar?
316 / 316L Stainless Steel Bar is an austenitic stainless steel alloy containing chromium, nickel, and 2–3% molybdenum. This addition enhances corrosion resistance—particularly against chlorides and acidic environments. The “L” version (316L) has a reduced carbon content, which helps prevent carbide precipitation during welding and improves its suitability for welded structures.
These bars are offered in multiple finishes and sizes, suitable for machining, structural frameworks, and marine components.
