Allegheny Ludlum AL 825 alloy is a nickel-iron-chromium-molybdenum-copper alloy with superior corrosion resistance including stress-corrosion cracking resistance. It is highly ductile from cryogenic to well over 1000 F(538 C) temperatures. It is readily weldable. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-366. Producer or source: Allegheny Ludlum Corporation.

Type 201L is a low carbon version of type 201, an austenitic Cr-Ni-Mn stainless steel. It maintains satisfactory intergranular corrosion resistance in applications involving welding, particularly heavier gage material. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as heat treating. Filing Code: SS-825. Producer or source: Allegheny Ludlum Corporation.

Allegheny Ludlum’s AL 625HP is an austenitic nickel-base alloy possessing exceptional fatigue resistance and developed for applications in bellow expansion joints. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming and joining. Filing Code: Ni-594. Producer or source: Allegheny Ludlum Corporation.

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.
