AS/NZS 1830 Casting
AS/NZS 1830 Casting material is the joint standard developed by Standards Australia and Standards New Zealand for grey cast iron.
The latest 2007 edition is identical with ISO 185:2005, which means it fully adopts the grade classification system, designation rules and property requirements of the international standard.
For the older editions before 2007, this standard used to have its own classification system:
– T-series: 7 tensile strength-based grades: T150, T200, T220, T250, T260, T300, T350
– H-series: 4 hardness-based grades for automotive and appliance applications.
These old-style grades are now obsolete, and the current standard is fully aligned with ISO 185.
