MEEHANITE type GM is a high strength iron which may be cast uniformly solid regardless of casting size or sectional deviation. This particular engineering material possesses true elastic properties, conferring both controlled stiffness and resilience which provides good impact strength and shock resistance in combination with high tensile strength and assured solidity. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on heat treating and machining. Filing Code: CI-25. Producer or source: Meehanite Metal Corporation.
