Standard Specification for Ferritic Ductile Iron Castings Suitable for Low-Temperature Service


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.


1.1 This specification covers ductile iron castings suitable for service at temperatures of 40°F [-40°C] and above.

1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.3 The following precautionary statement pertains only to the test methods portion, Section , of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
