Alloy 317L (UNS S31703) is a molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steels such as Alloy 304. In addition, Alloy 317L offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. It is a low carbon or "L" grade which provides resistance to sensitization during welding and other thermal processes.
Carey Alloys Metal is a stock a full range of stainless round bars from 8mm diameter to 600 mm forged bars with 4 meters to 6 meters length. Nearly all grades of stainless steel are stocked in round bar, including 302, 303, 304/L, 304H, 309/S, 310/S,316/L,317/L, 321, 321/H, 347, 347H, 410, 416, 420, 440C,17-4PH,Duplex 2205 and Alloy 20. We manufacture products such as Steel Rounds, Squares, Hexagons, RCS and Bright Bars of various grades which are used as raw material by various manufacturers of Engineering, Forging, Bright Bars, Auto Components goods.
317L is a molybdenum bearing, low carbon content "L" grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding. 317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion.
Alloy 317L is an austenitic stainless steel that combines excellent high temperature properties with good ductility and weldability. It is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and superior strength in temperatures up to 2100°F. Due to its high chromium and nickel content, it is superior to 310 or 310S stainless in most environments.
