CANNON-MUSKEGON A-2 is a high-carbon air-hardening cast tool steel with excellent non-deforming properties and abrasion resistance in the quenched and tempered condition. It has good machinability in the annealed condition. A higher silicon content is permissible in this cast steel than in AISI A2 (wrought) tool steel. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on casting, heat treating, machining, and joining. Filing Code: TS-257. Producer or source: Cannon-Muskegon Corporation.
