Stainless Steel AISI 316

Data sheet
DIN EN 10088-3
Grade AISI 316 / EN 1.4401

The material AISI 316 / EN 1.4401 is an austenitic chrome-nickel-molybdenum stainless steel. The molybdenum content provides high corrosion resistance to non-oxidising acids and chlorine-containing materials. This stainless steel grade has low magnetization and is suitable for welding, forging and cold forming. Please note, however, that the material AISI 316 / EN 1.4401 does not have any resistance to intergranular corrosion in the welded state.
