High-pressure three-way, three-way, three-way alloy steel, alloy steel tee factory, three standard tee, alloy steel tee, alloy steel, three the factory alloy steel tee Profile: made of alloy steel three-way add the appropriate amount of one or more alloying elements consisting of iron-carbon alloy steel, on the basis of the ordinary carbon steel. According to the different additive elements, and take the appropriate processing technology, the availability of high strength, high toughness, wear-resistant, corrosion-resistant, low temperature, high temperature, non-magnetic and other special properties. The main alloying elements of the alloy steel, silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth. Vanadium, titanium, niobium, zirconium and steel is strong carbide forming elements, as long as there is enough carbon, under appropriate conditions, will be able to form their own carbide, when the lack of carbon or in high temperature conditions by atomic state into the solid solution; manganese, chromium, tungsten, molybdenum carbide forming elements, some of which atomic state into the solid solution, another part of the formation of substitutional alloy cementite; such as aluminum, copper, nickel, cobalt, silicon is not formed carbide elements, generally present in solid solution in atomic state. Many types of alloy steel, usually by the content of alloying elements is divided into how many low-alloy steel (less than 5%), alloy steel (content of 5% to 10%), high-alloy steel (content> 10%); divided by mass quality alloy steel, trait is divided into alloy steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, bearing steel, alloy spring steel and special properties of steel (such as soft magnet alloy steel; characteristics and uses permanent magnet steel, non-magnetic).
