Description
Stainless steel 316/316L is an 18/8 austenitic stainless steel enhanced with an addition of 2.5% Molybdenum, to provide superior corrosion resistance to type 304 stainless steel. 316/316L has improved pitting corrosion resistance and has excellent resistance to sulphates, phosphates and other salts. 316/316L has better resistance than standard 18/8 types to sea water, reducing acids and solution of chlorides, bromides and iodies.
Applications:
Include pumps, valves, marine fittings, fasteners, paper and pulp machinery, and petro chemical equipment.
