Annotation of standard text ASTM A439/A439M-18(2026) :
This specification covers austenitic ductile iron castings used for their resistance to heat, corrosion and wear. The castings shall be melt processed using cupolas, air furnaces, electric furnaces or crucible furnaces. The iron castings shall undergo magnetic permeability test. Samples taken from test coupons, broken test specimens, or castings shall conform to the required chemical compositions of carbon, silicon, manganese, phosphorus, nickel and chromium. Mechanical tests shall be performed wherein the iron casting specimens shall conform to the required values of tensile strength, yield strength, elongation and Brinell hardness.
