AISI Type 1.2 is a chromium-vanadium tool steel of modest hardenability and variable carbon content (nominally 0.50-1.10% carbon). At its lower carbon levels, it is used for tools requiring toughness and resistance to shock and vibration. At its higher carbon levels, it is recommended for resistance to abrasion, fatigue and wear. It is used for both hot-work and cold-work applications. Among its many uses are automotive gears, forgings, gun barrels, shafts, wrenches, chisels, punches, lathe spindles, axes, shear blades, dies, files, reamers and drills. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-416. Producer or source: Tool steel mills.
