EN 1.4404 / UNS S31603 / 316L

Material description

EN 1.4404 / UNS S31603 / 316L is a molybdenum-alloyed austenitic chromium-nickel steel with improved machinability.

The grade is used for a wide range of industrial applications where steels of types ASTM 304/304L have insufficient corrosion resistance. Round bar is supplied in solution annealed and peel turned condition.

Our Green Line (Specific for Plates)

Our Green Line is among world’s most sustainable stainless steel. It has the lowest carbon footprint in the industry — a reduction of up to 90 % compared to the global industry average. It is third-party verified (by SGS acc. to ISO 14 0687) and in full compliance with NORSOK M-630 – MDS S15.
Applications

The austenitic stainless steel EN 1.4404 / UNS S31603 / 316L shows good acid resistance. Material AISI 316L is used in the chemical industry, apparatus engineering, sewage plants and piping industry.

Heat Treatment – Solution annealed and quenched in air or water.

Weldability – Very good.
