Allegheny Ludlum's 317L™ 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 317L™ 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. This alloy is intended for severe service conditions such as flue gas desulfurization (FGD) systems. Information provided by Allegheny Ludlum Corporation. |
