STORA ASP 23 high-speed tool steel offers very good abrasion resistance and resistance to softening at elevated temperatures. The excellent size stability and good grindability of this steel make it highly suitable for tools of complicated shape, such as hobs, broaches and threading dies. The high combination of wear resistance, tensile properties and toughness make ASP 23 suitable also for cold-work tools. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-334.
