Effects of Heat-Treatment on the Microstructure and Wear ...

The variations of microstructure and mechanical properties of a high-chromium cast iron for rolls were studied from as-cast to the final heat treatments. Results show that the as-cast microstructure of the HCCI consists of M7C3 carbide, M23C6 carbide, martensite matrix, and retained austenite. The large dendritic M7C3 carbide surrounds the matrix, and the M23C6 carbide is mainly distributed in ...

Heat Treating of High-Alloy White Irons :: Total Materia ...

An austenitizing heat treatment usually comprised heating at temperatures between 750 and 790°C (1380 and 1450°F) with a soak time of 8 h. Air or furnace cooling, not over 30°C/h, was conducted followed by a tempering/stress-relief heat treatment. Refrigeration heat treatment is the more commonly practiced remedy for low hardness today.

Induction hardening - Wikipedia

Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched.The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.

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.
