High chromium white cast irons are ferrous alloys with chromium contents of 11 to 30 wt% and 1.8 to 3.6 wt% carbon [ 1 ]. Elements such as Molybdenum, Nickel and Copper are also added to suppress the transformation to pearlite and improve their hardenability.

9/4 · The initial as-cast structure of a high-chromium white iron consisted of primary austenitic dendrites and a eutectic mixture of M 7 C 3 /austenite. Cr depletion of the matrix in the close vicinity of the carbide particles had led to their engulfment by a thin martensite layer.

However, the percentage of dissolved eutectic carbides is also higher. Heat Treatments of Austenite in High Chromium White Cast Iron, Alloyed with Mo.

High Chromium Casting, High-chromium alloy casting and forging, high-chromium castings is called high-chromium casting or steel castings, and is a chromium-based white cast iron. It is a kind of grinding medium among ordinary white cast iron and nickel hard white iron developed from the third generation of chromium-based wear-resistant materials.

In the as-cast condition, the microstructure of high chromium molybdenum white iron consists essentially of dendrites of austenite in a matrix of eutectic mixture of austenite and (Fe, Cr) 7 C 3 carbides [ 4, 5 ]. For many applications, castings are heat treated prior to service to increase the wear resistance as well as impact toughness.

High chrome white iron cast alloy's superior wear resistance is due primarily to a high volume fraction of very hard, well-dispersed primary and secondary carbides in a matrix of martensite. The high chromium content provides good resistance in corrosive environments and good oxidation resistance. COMPOSITION C % 2.0 - 3.5 Mn % - 1.5 max.

High chromium hardened white cast iron (HCWCI) is widely used in processes having high mechanical requirements and wear resistance but having limited toughness. Its wear resistance is directly linked to its microstructure and the addition of alloy elements [ 1 ].

The objective of the present work is to establish the heat treating parameters necessary to impose to a pair of high chromium white cast irons a hardness figure in the range from 35 to 40 HRC, acceptable to guarantee a reasonable machinability of the material. Samples of two high chromium white cast irons have been isothermally annealed under

High chromium white cast iron is the best combination of abrasion resistance and toughness. Chromium content variation and heat treatment can be used to adjust the mechanical properties as there is a trade-off between wear resistance and toughness of cast iron. ASTM A 532 standard has two set standards for compositions and hardness.

This work studies plastic behaviour and its influence on the abrasive wear resistance of a group of high chromium white cast irons. The irons were poured in 

Long term industrial practice shows that chromium white cast iron has excellent stability and relatively low production cost in high temperature and high wear environment. Therefore, it is widely used in mining and mineral processing, cement production, pulp and paper industry to grind hard materials, such as ore, coal, gravel and cement.

High chromium white cast iron has different matrix structures in different treatment states. There are austenite in casting state, pearlite in annealing state, martensite in quenching state, and tempered martensite in tempering state. All of them contain (Fe,Cr) 7 C 3 type eutectic carbide. In this experimental condition, heat treatment has
