Product Code:SAE J2477
Title:Automotive Austempered Ductile (Nodular) Iron Castings (ADI)
Issuing Committee:Automotive Iron And Steel Castings Committee
Scope:This SAE Standard covers the mechanical and physical property requirements for Austempered Ductile Iron (ADI) castings used in automotive and allied industries. Specifically covered are:a. Hardnessb. Tensile Strengthc. Yield Strengthd. Elongatione. Modulus of Elasticityf. Impact Energyg. MicrostructureIn this document SI units are primary and in-lb units are derived. Appendix A provides general information and related resources on the microstructural, chemical and heat treatment requirements to meet the mechanical properties needed for ADI in particular service conditions and applications.
