Allegheny Ludlum Stainless Steel Chromium-Nickel-Molybdenum 317LXN™ (UNS S31726)
Subcategory: Stainless Steel; T 300 Series Stainless Steel; Metal
Key Words: Plate, sheet, and tube spec is ASTM A-240
Material Notes: Iron content above calculated as balance. Allegheny Ludlum's 317LXN™ is molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steels such as Type 304. AL 317LXN™ alloy also offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. The alloy has low carbon to provide resistance to sensitization during welding and other thermal processes. The combination of increased levels of molybdenum and nitrogen enhance resistance to pitting and crevice corrosion especially in process steams containing acids, chlorides and sulfur compounds at elevated temperatures. Nitrogen also serves to increase the strength of this alloy. This alloy is intended for severe service conditions such as flue gas desulfurization (FGD) systems.
