Abstract

UHB-S7 is a tool steel characterized by its high hardenability and excellent impact properties. At Rockwell C 59 it has a compressive strength of over 600,000 psi, a tensile strength of 340,000 psi, and a Charpy (no notch, smooth) impact value of more that 140 foot-pounds. It is suitable for a wide range of tool and die work for both hot-shock and cold-shock applications. 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 surface treatment. Filing Code: TS-350. Producer or source: Uddeholm Aktiebolag.
