AL 468 is an 18% chromium stainless steel with dual stabilization by titanium and columbium. Small angular carbonitrides of both titanium and columbium are randomly dispersed, but develop improved surface quality, strength, and oxidation resistance when compared to Type 439. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-597. Producer or source: Allegheny Ludlum Corporation.
