Production of Steel Bonded Carbide

Steel bonded carbide is hard compounds (carbides, nitrides, borides, etc.) for the hard phase in order to bond metal carbide steel. Steel bonded carbide Lancome has both carbide hardness and wear resistance, but also has good mechanical properties of steel used in a range between high-speed steel and carbide. In some cases, the wear resistance of steel bonded carbide and carbide is better than plastic. Especially steel bonded carbide body contains large amounts of steel (alloy 50% by volume or more), the alloy can be heat treated and machined. Steel bonded carbide in other aspects of the development and applications include: (a) steel bonded carbide hard facing diversified development, such as WC, TiC, TiN, TiCN, TiC-A12O3, TiB, TiB-TiN, etc. variety of new hard phase, particularly TiB2 with high hardness, high Young's modulus, good high temperature strength and stable chemical properties, are wear parts, cutting tool material of choice. (2) steel bonded carbide bonded phase steels continues to expand, such as the various components of carbon steel, alloy steel, tool steel, high speed steel, high manganese steel, heat resistant steel and stainless steel. (3) The method for producing steel bonded titanium carbide by conventional powder metallurgy method, a dipping method, a hot press method developed for the hot isostatic pressing (HIP), sintering HIP method (Sinter - HIP), etc..

Preparation of Steel Bonded Carbide

Heat treatment of steel bonded carbide heat treatable steel bonded carbide having sex. Heat treatment of steel bonded carbide include annealing, quenching and tempering heat treatment process of its development depends on the steel binder composition and ultimately the required performance, in general, with the original steel heat treatment process similar.

Steel Bonded Carbide Composition and Performance

Steel bonded titanium carbide-based cemented carbide and titanium carbide in a steel composition ratio of the alloy after annealing has an important influence processability, hardness of the alloy with titanium carbide increases with the content. In recent years, developed a new type of TiC with TiN replace steel bonded carbide, steel bonded carbide is an important development. Mitsubishi Metal Corporation produced a high-speed steel matrix containing uniformly dispersed titanium carbide and titanium nitride new carbide, and is called "Chotaigokin" alloys.
