Many different types of steel, usually divided by the number of elements in low alloy steel (content <5%), in alloy steel (content of 5% to 10%), high alloy steel (> 10%); according to quality into high-quality alloy steel, alloy steel qualities; by characteristics and purposes are divided into alloy steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, bearing steel, spring steel and alloy steel special properties (such as soft magnet , magnetic steel, non-magnetic), etc.
In addition to steel, iron, carbon and small amount of unavoidable silicon, manganese, phosphorus, sulfur, it also contains a certain amount of alloy elements in steel alloying elements are silicon, manganese, molybdenum, nickel, Ge, alumina, titanium , niobium, boron, lead and rare earth in which one or several, all of this steel alloy called alloy systems, with their own resources, production and use conditions vary, the development of nickel has been abroad in the past, Ge steel system, China is found to be silicon, manganese, vanadium, titanium, niobium, boron, lead, rare earth-based alloy system alloy in steel production accounts for about ten per cent, usually in an electric furnace smelting the steel-use can be divided into eight categories, which are: alloy steel, spring steel, bearing steel, alloy tool steel, high-speed tool steel, stainless steel, heat-resistant steel can not afford leather, electrical silicon steel used.
The company is a sales and processing integrated enterprise, there are 15,000 kinds of imported materials.
