Alloying has a multidimensional effect on steel quality. Chromium increases hardness and corrosion resistance. Nickel makes the alloy ductile; tungsten makes it hard, red-hot. Vanadium increases strength, impact and abrasion resistance; cobalt increases heat resistance and magnetic permeability. Molybdenum makes the alloy red resistance, strength, resistance to oxidation at high temperature. Manganese content above 1% increases hardness, impact strength, wear resistance. Titanium increases stability, corrosion resistance; aluminum, scale resistance; niobium, acid resistance. Copper increases ductility and prevents rusting. High-quality steel, in addition to the above components, contains boron, zirconium, selenium and nitrogen.
Several types of treatment are used in the production of products of this grade, which determine the physical and mechanical properties of steel:
- high-narghened;
- case hardened;
- half-blasted.
