This specification covers ductile iron castings suitable low temperature service. Castings shall be produced by casting or heat treatment and shall have essentially a ferritic structure that contains no massive carbides. The iron shall conform to the required chemical composition for carbon, silicon, phosphorus, magnesium, manganese, copper, nickel and chromium. The iron shall conform to the required tensile properties such as tensile strength, yield strength and elongation. Graphite contained in the microstructure shall be evaluated and the percentage of each graphite type shall be estimated. The surface of the casting shall be examined visually and shall be free from adhering sand, scale cracks, and hot tears.
