UHB TRI-Z is a high-carbon high-chromium tool steel with an absolute minimum of nonmettalic inclusions. It is an air hardening steel having high resistance to abrasive wear. It is recommended for intricate dies where maximum accuracy in heat treatment and high production are essential. It is also very suitable for working rolls in Sendzimir Cold Rolling Mills (which is implied by the letter Z). This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-184. Producer or source: Uddeholm (Canada) Ltd.
