Automotive Austempered Ductile (Nodular) Iron Castings (Adi)
J2477_200303
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. Hardness
b. Tensile Strength
c. Yield Strength
d. Elongation
e. Modulus of Elasticity
f. Impact Energy
g. 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.
