Heat Treatment of Cast Irons 2018-12-12 Industrial Heating

Dec 12, 2018· The most common heat treatment applied to gray cast irons is stress relief because of non-uniform cooling of castings and annealing to improve machinability. Subcritical heating is used for both. Stress relief is done at temperatures between 550-650°C (1020-1200°F) without significantly lowering strength and hardness.

annealing and re-hardening ASTM A532-93 Class III Type A

My question is, can high chrome cast iron be "heat treated" to re-harden to 500 HB after annealing or even tempering to 400? Some of the curves in the "Abrasion Resistant Cast Iron Handbook" suggest some high chrome irons can end up with vastly different hardnesses even after tempering to the same temperature, depending on retained austenite.
