The main alloy steel elements have silicon, manganese, chromium, nickel, tungsten, molybdenum, vanadium, titanium, niobium and zirconium, cobalt, aluminum, copper, boron, rare earth, etc. Which vanadium, titanium, niobium and zirconium, etc in steel is strong carbide form elements, as long as there is enough carbon, in the right conditions, to shape their own carbide, when lack of carbon or in high temperature conditions, the one with atomic state into the crystallology; Mn, chromium, tungsten, molybdenum carbide form elements for, some of the atoms in the state to enter the crystallology, another part of form replacement type alloy cementite; Aluminum, copper, nickel, cobalt, silicon carbide is not formed elements, general with atomic state exists in the crystallology.
Alloy steel type many usually according to how much content alloy elements into low alloy steel (< 5%), the content of alloy steel (with the content of 5% ~ 10%), high alloy steel (content > 10%); According to quality into high quality alloy steel, alloy steel qualities; According to the characteristic and purpose and divided into alloy steel and stainless steel, acid, steel, wear-resisting steel, heat-resistant steel, alloy steel, rolling bearing steel, alloy spring steel and special performance steel (such as soft magnets, everlasting, no pumpbody magnets), etc.
In the steel in addition to iron, carbon and a small amount of inevitable silicon, manganese, phosphorus, sulfur elements, but also contains a certain amount of alloying elements, the steel alloy elements have silicon, manganese, molybdenum, nickel, luo, ", titanium, niobium, boron, lead, rare earth and the one or several, this steel that the system of alloy steel alloy steel, with their respective resource situation, production and use different and different conditions, foreign had development nickel, luo steel system, our country it found that by silicon, manganese, vanadium, titanium, niobium, boron, lead, rare earth primarily alloy steel system in the total output of steel alloy steel accounts for about of the more than ten, general is in the use of electric smelting in the alloy steel can be divided into 8 categories, they are: structural alloy steel, spring steel, bearing steel, alloy steel, high speed steel, stainless steel, heat-resistant not peeling steel, electrician use silicon steel.
