Austempering
Heat treating process of components made of cast iron with spheroidal graphite and parts made of tool and high-speed steels.

Stamping and hardening
The company provides services of hot and cold stamping: contouring process, punching process, bending / unbending process, etc. The production of parts of various steels and alloys by combining the operations of sheet-metal stamping and hardening by heating blanks to a temperature above the transformation temperature, holding a part at this temperature, stamping (the process of plastic deformation of a material with changing the shape and sizes of the blank), rapid oil cooling (at a rate higher than the critical one) and tempering to reduce internal stresses and produce a more equilibrium structure.
