Automotive Austempered Ductile (Nodular) Iron Castings (ADI)
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:
b. Tensile Strength
c. Yield Strength
e. Modulus of Elasticity
f. Impact Energy
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.
