1. A study was made of the following methods of milling of ferrochromium: in a vibratory ball mill under alcohol and acetone and in a planetary mill. The most effective was milling for 30 min in the planetary mill, which comminuted 90% of ferrochromium to a particle size of less that 200. 2. The optimum conditions for the production of TiC-Kh12M-steel materials (50, 40, 35, and 30% TiC) with chromium added to the steel in the form of ferrochromium powder were found to be a pressing pressure of 3 tons/cm2, a vacuum sintering temperature of 1430-1470C, and a sintering time of 1 h. The optimum conditions for the heat treatment (annealing, quenching, and tempering) of these materials were determined. 3. Some of the key properties of the materials were investigated. It was established that the properties of TiC -Kh12M-steel materials alloyed with chromium in the form of ferrochromium are virtually identical with those of the same materials containing additions of pure chromium powder. Ferrochromium, however, being cheaper and more readily available than chromium powder, should be used as a starting material in the manufacture of titanium-carbide-steel alloys.

The alloy Ferrochrome contains two elements: Iron (Fe) and Chromium (Cr). Ferrochrome usually contains between 50-70% Chromium. It has the chemical formula of FeCr.

Chrome ore is usually for production of ferrochromium and chrome, which is widely used in metallurgical industry, refractory matter, chemical industry and so on. Chrome ore is one of the most valuable metal ore in the world. Chrome ore mining and beneficiation is an important industry in some countries such like Pakistan (Muslim Bagh) South Africa, and so on.

chromium element is used as alloy element in stainless steel used for cooking utensils etc and also used for electroplating example in automotive parts like front grill for glossy look . Hard chrome plating is used to improve wear resistance of moving parts like engine components like piston pins etc.
