Elements reducing the steel propensity to corrosion or elements changing the more dangerous corrosion form to less dangerous (for example, the intergranular corrosion transition in uniform one) specially introduced in steel composition during alloying.
Chromium, nickel, aluminum and silicon separately or together in various proportions often introduce into steel. These elements presence in sufficient quantities makes the steel resistant in water, in humid atmosphere, in many acids and alkalis solutions and in dry gases atmosphere at high temperatures. Erosion resistance increases in steels with a high carbon content. Energosteel company uses such high-carbon steel, alloyed with chromium, manganese and silicon for the grinding balls fifth hardness group production (DSTU 3499-97 / DSTU 8538: 2015).
Energosteel Company uses steel, specially developed our specialists together with hot-rolled round products suppliers for production grinding balls the 3-rd and 4-th hardness groups (DSTU 3499-97 / DSTU 8538: 2015). These steels contain a certain number of alloying elements (silicon, chromium, manganese, vanadium, molybdenum, titanium), that change the metal mechanical properties in micro volumes simultaneously increasing the corrosion resistance.
