Automotive Ductile Iron Castings for High Temperature Applications

Automotive Iron and Steel Castings Committee
  • Ground Vehicle Standard
  • J2582_200112
  • Historical
Published 2001-12-18 by SAE International in United States
This SAE Standard covers the hardness, chemical analysis and microstructural requirements for ductile iron castings intended for high temperature service in automotive and allied industries. Commonly known as SiMo ductile iron, typical applications are in piston-engine exhaust manifolds and turbocharger parts. Castings may be specified in the as-cast or heat treated condition. For design purposes, the Appendix provides general information on the application of high temperature ductile iron castings, their processing conditions, chemical composition, mechanical properties and microstructure.

Automotive Gray Iron Castings

Automotive Iron and Steel Castings Committee
  • Ground Vehicle Standard
  • J431_199303
  • Historical
Published 1993-03-01 by SAE International in United States
This SAE Standard covers the hardness, tensile strength, and microstructure and special requirements of gray iron sand molded castings used in the automotive and allied industries. Specific requirements are provided for hardness of castings. Test bar tensile strength/Brinell hardness (t/h) ratio requirements are provided to establish a consistent tensile strength-hardness relationship for each grade to facilitate prediction and control of tensile strength in castings. Provision is made for specification of special additional requirements of gray iron automotive castings where needed for particular applications and service conditions. Note: This document was revised in 1993 to provide grade specific t/h control. In 1999 the document was revised to make SI metric units primary. To better align the grading system with long established production methods and grades produced, the previous system of grading by fixed combinations of tensile strength and hardness was changed in 1999 to a system of grading by variable combinations of test bar t/h ratio and casting hardness grades. The number of hardness grades was increased relative to the number of previously available ranges to…
