Steel Alloys manufactures various types of 316 stainless steel products. Equivalent to standard SS316, it includes UNS S31600, WERKSTOFF NR. 1.4401 / 1.4436, AFNOR Z7CND17‐1102 ,ENX5CrNiMo17-12-2 / X3CrNiMo17-13-3, JIS SUS 316, and BS 316S31 / 316S33. This stainless steel has a composition with 0.08% Carbon, 0.75% Silicon, 2.0% Manganese, trace amounts of Sulfur and Phosphorus, 16.0-18.0% Chromium, 2.0-3.0% Molybdenum, 10.0-14.0% Nickel, and 0.10% Nitrogen.

316 stainless steel is known for its physical properties, such as a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa, with maximum hardness values of Rockwell B (HR B) 95 and Brinell (HB) 217. It’s widely used in industries like pharmaceuticals, food processing, hospitals for surgical implants, marine parts, and industrial equipment handling corrosive chemicals. Notably, its low carbon content minimizes carbide precipitation during welding processes
