AL TECH HTB-2 is a chromium-molybdenum-vanadium steel that is a lower molybdenum high-speed steels. It has a high hardenability and is a vacuum-melted steel for bearings. It is especially suited for highly loaded bearings in gas turbine enginens operating at elevated temperatures under critical service requirements. It has outstanding resistance to wear and softening at temperatures up to 800 F and also exhibits relatively good oxidation resistance. HTB-2 is furnished in both the single vacuum-melted and double vacuum-melted condition. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and machining. Filing Code: TS-417. Producer or source: AL Tech Specialty Steel Corporation.
