CANNON-MUSKEGON H-11 is an air-hardening hot-work cast tool steel used for hot applications requiring good toughness combined with good red-hardness and for cold applications where toughness is required at the sacrifice of some wear. A higher silicon content is permissable in this cast steel than in AISI H-11 (wrought) tool steel. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on casting, heat treating, machining, and joining. Filing Code: TS-251. Producer or source: Cannon-Muskegon Corporation.
