The invention discloses a high-chrome wear-resistant cast iron material and a heat treatment method. The high-chrome wear-resistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and copper as auxiliary materials in manners of melting and casting after preparation.

Heat Treatment and Properties of Iron and Steel

The properties of cast iron also may be modi- fied by the presence of alloying elements—such irons are called alloy cast irons. 2. Properties of Iron Since iron is the basic element of steel, a knowledge of some of its properties is dataa pre- requisite to an understanding of the funda- mental principles underlying the heat treatment of steels. 2.1.

Nickel-chromium white iron castings are given a stress-relief heat treatment because, properly made, they have a martensitic matrix structure, as-cast. Tempering is performed between 205 to 260°C (400 to 450°F) for at least 4 h.

Heat treating cast iron -

I agree with the idea of case hardening on cast iron. To do any heat treat you should know the carbon content and other ingredients. Nitriding, induction hardening, hard chrome plating are all ways of treating parts like cams that have to be abrasion resistent.
