Alloyed cast steel is categorized as either low or highalloy. Lowalloy cast steel (≤ 8 percent alloy content) behaves similar to normal carbon steel, but with higher hardenability. Highalloy cast steel (> 8 percent alloy content) is designed to produce a specific property, such as corrosion resistance, heat resistance, or wear resistance.

The purpose of the heat treatment is to increase the ductility of the cast iron. However, this process is now outdated since spheroidal graphite can be produced directly on casting by inoculating with magnesium or cerium. All samples are etched using 2% nital.

My question is, can high chrome cast iron be "heat treated" to reharden 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.

White cast iron does not have the easy castability of other cast irons because its solidification temperature is generally higher, and it solidifies with C in its combined form as iron carbide. White cast iron has a high compressive strength and excellent wear resistance, and it retains its hardness for limited periods even up to a red heat.

Microstructure and erosioncorrosion behaviour of ascast high chromium white irons containing molybdenum in aqueous sulfuricacid slurry was studied. The experimental irons contained 28 wt.%Cr with a Cr:C ratio of about 10 and up to 10 wt.%Mo. The irons with up to 6 wt.%Mo are hypoeutectic, whereas the iron with 10 wt.%Mo becomes eutectic/peritectic. Mo addition promotes formation of .
