JSC "Severstal-metiz" expands a portfolio of technologies chemical heat treatment of metals

The Cherepovets enterprise JSC "Severstal-metiz" mastered technology nitriding – hardenings of a surface of metals with help ammonia. Thanks to what firmness of products on the average grew by 30 percent. For development of new technologies in tool shop launched in work the specialized furnace. In it under the influence of temperature (from 450 to 550? C) and at continuous giving ammonia a blanket metals are sated with nitrogen. As a result it gets the increased microhardness and, as a result, the increased operational properties: high durability, wear resistance and corrosion resistance...
