DUCTLIRON is a high-carbon ferrous material containing graphite in the form of nodules or spheroids. It possesses unusually high ductility, strength and castability. It is furnished in three different grades, namely, SF-60, SP-80 and SH-100. Alloyed grades are also available under different designations as AQS-HS and WS. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on casting, heat treating, machining, and joining. Filing Code: CI-33. Producer or source: Rosedale Foundry.
