Alloying has a multifaceted effect on the quality of the steel. Chromium increases the hardness, corrosion resistance. The Nickel gives the alloy ductility; tungsten hardness, red hardness. Vanadium increases the strength, resistance to impact and abrasion; cobalt increases heat resistance, magnetic permeability. Molybdenum alloy imparts red-hardness, strength, opposition to oxidation at high temperature. The proportion of manganese is above 1% increases the hardness, toughness, durability. Titanium increases the stability, corrosion resistance; aluminium — resistance to scale formation; niobium — acid. Copper increases the ductility, prevents rusting. Particularly high-quality steel in addition to the above components contains boron, zirconium, selenium, nitrogen.

In the manufacture of a given brand uses several types of processes which determine the physical and mechanical properties STLI:

  • vysokokachestvennoj;
  • nagarebana;
  • polonikova.
