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.

These cast irons have acceptable properties as cast. This eliminates the need for a costly heat treatment and makes them a cost effective alternative to other grinding materials. Reduced levels of austenite formers such as nickel and manganese also minimie the retention of low temperature austenite - a potential cause of premature failures.

High Chromium White Cast Iron High Cr White Iron High Chromium White Cast Iron or High Cr White Iron grades are used in wear applications that require some corrosion resistance. The high chromium content offers the corrosion resistance and the fine carbides dispersed throughout provide the hardness. These grades cannot be welded.

High carbon high chrome steels are heat treatable as a consequence of the higher carbon content and are known as martensitic stainless steels e.g. 410 416. They do however exhibit lower corrosion resistance due to chromium depletion of the oxide film. They exhibit good strength and oxidation resistance up to 750C although their creep
