ATI Allegheny Ludlum Type 317 Stainless Steel, UNS S31700
Categories:	Metal; Ferrous Metal; Stainless Steel; T 300 Series Stainless Steel
Material Notes:	This is a molybdenum-bearing austenitic stainless steels which is more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature. Types 317 and 317L containing 3 to 4% molybdenum are preferred to Types 316 or 316L which contain 2 to 3% molybdenum in applications requiring enhanced pitting and general corrosion resistance. Austenitic stainless steels with higher molybdenum or molybdenum plus nitrogen content which provide even greater resistance to pitting, crevice corrosion an general corrosion are also available in flat-rolled products from Allegheny Ludlum. Properties of these alloys are described in separate technical data publications available from Allegheny Ludlum. In addition to excellent corrosion resistance and strength properties, this alloy also provides the excellent fabricability and formability. This is available in the form of sheet, strip and plate to ASTM A240 and ASME SA-240 and other pertinent specifications. Information provided by Allegheny Ludlum
