ASTM A479 UNS S31603 316L Stainless Steel Round Bar is a premium austenitic stainless steel round bar manufactured according to ASTM A479 specification and equivalent to EN 10272 1.4404 stainless steel bar. It is widely used for pressure equipment, chemical processing, marine engineering, pharmaceutical machinery, and other applications requiring excellent corrosion resistance and high durability.
UNS S31603 is the low-carbon version of 316 stainless steel, commonly known as 316L stainless steel. The reduced carbon content improves resistance to intergranular corrosion after welding, making it an ideal choice for welded structures and components exposed to corrosive environments.
JUDE STEEL supplies ASTM A479 UNS S31603 316L stainless steel round bars in various diameters, surface finishes, and customized dimensions with EN 10204 3.1 material certificates available.
