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:
-
Hardness
-
Tensile Strength
-
Yield Strength
-
Elongation
-
Modulus of Elasticity
-
Impact Energy
-
Microstructure
In 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.
