Abstract

Allegheny Ludlum AL-6XN alloy is characterized as a superaustenitic stainless steel having an exceptional level of corrosion resistance, especially to chloride pitting. It has high strength and its impact value at room temperature is 140 ft-lb and at 320 F (196 C) is 85 ft-lb. It is covered by ASME Boiler and Pressure Vessel Code (Case 1997 for Section VIII and Case N-438 for Section III Construction). This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-494. Producer or source: Allegheny Ludlum Corporation.
