SAE J 431-2000 (SAE J431-2000)
Automotive Gray Iron Castings
This SAE Standard covers the hardness, tensile strength, and microstructural and special requirements for gray iron sand mold castings used in 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.
