SAE J2477 – Automotive Austempered Ductile (Nodular) Iron Castings (ADI) (Stabilized: Jan 2018)

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:

1. Hardness

2. Tensile Strength

3. Yield Strength

4. Elongation

5. Modulus of Elasticity

6. Impact Energy

7. 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.
