Introduction The purpose of standard specifications for Ductile Iron castings is to provide a body of information which can be used with confidence by both designer and foundry to select, define and agree upon a set of specific properties which will ensure that the castings meet the intended use of the designer.
This standard specifies chemical, physical, and hardness requirements. It is up to the designer to specify a set of properties – mechanical, physical, chemical or dimensional – which best suit the casting to its purpose.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Historical Version s – view previous versions of standard. The mechanical properties are given for information only.
Through commitments to SPC and continual quality improvement, many foundries have developed the capability to produce castings whose higher quality can be demonstrated statistically. This standard specifies that all castings shall be heat treated by annealing between and o F for 1 hour per inch of casting section and furnace cooling.

Introducing some sand casting foundries in USA and China, whose main products are various gray iron, ductile iron and steel sand castings. Boiling Point o F.
Brinell hardness range HB. Tensile strength, min, ksi MPa. Minimum impact resistance values in J. Mechanical property values are given in the units normal to the particular specifying body. The values for the materials normally apply to castings with thicknesses between 30 mm and mm and adtm a mass greater than kg or when the relevant wall thickness may vary between 30 mm and mm.
Tensile strength, min, psi. There are many additional standards for Ductile Iron, some national, and others valid only within a specific technical or commercial organization. This standard, and its replacement, the EuroNorm standard EN will become increasingly important with the formation of the European Community.
Mechanical properties of cast-on test sample. SAE specification for Ductile Iron casting and austempered Ductile Iron casting are currently being revised so they were not available as of the time of this printing.
Standard specifications for Ductile Iron are normally based on mechanical properties, except for those defining austenitic Ductile Iron, which are based on composition. This specification covers austenitic ductile iron castings for compressors, expanders, pumps, valves, and other pressure-containing parts intended primarily for low-temperature service.
HB, kgf load to Mechanical properties measured on test pieces machined from separately cast samples. Such instructions should be used judiciously, because they almost invariably increase the casting cost and restrict the number of foundries which can provide competitive bids.
Sand Casting Foundries Introducing some sand casting foundries in USA and China, whose main products are various gray iron, ductile iron and steel sand castings. Elongation in 2 in.

Range specified by agreement. Chief thickness of iron casting mm. The values for the materials apply to castings cast in sand moulds of comparable thermal diffusivity. Minimum impact resistance values measured on V-notched test pieces machined from cast-on samples. Main sand casting products include truck, tractor and machinery parts, pump and valve parts, stove and boiler parts, manholes and pipe fittings.
