Types 316 (UNS S31600), 316L (S31603), 317 (S31700) and 317L (S31703) molybdenum-is stainless steels austenitic more resistant to general corrosion and pitting / crevice corrosion than the conventional chromium-nickel stainless steels austenitic such as 304. Type of alloys also offer higher creep, -strus-to rupture and tensile strength at elevated temperatures. In addition to corrosion resistance and excellent strength properties, the Types 316, 316L, 317 and 317L alloy Cr-Ni-Mo also provide the excellent fabricability and formability which are typical of the austenitic stainless steels.
Applications include for Types 316 and alloy 316L compounds acetic acid, vats brandy, products corn screening equipment, fasteners, kettles for cooking ketchup, processing equipment, pharmaceuticals, industrial parts phosphate, processing equipment photographic film, pitting-corrosion resistance, equipment pulp and paper processing, smokestacks, textile finishing equipment, textile mill Kiers, water softener tanks, wire cloth and screens (industrial) and yeast tubes.
There are 316 types, 316L, 317 and 317L more resistant to atmospheric and other mild types of corrosion than types 302, 304 and 304L. In general, the media do not corrode Types 302, 304 and 304L, will not attack the grades of molybdenum in them. One exception known highly oxidizing acids such as nitric acid to the molybdenum-stainless steels are less resistant.
