Unequal Tee A234 WP5 20Inch x SCH 30,14Inch x SCH80

The material of alloy steel tee is alloy steel, which is composed of iron carbon alloy by adding appropriate amount of one or more alloy elements on the basis of ordinary carbon steel. High strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non-magnetic properties can be obtained according to the different elements added and appropriate processing technology.

The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc. Vanadium, titanium, niobium, zirconium, etc. are strong carbide forming elements in steel. As long as there is enough carbon, they can form their own carbides under appropriate conditions. When carbon is lacking or at high temperature, they enter solid solution in atomic state; manganese, chromium, tungsten and molybdenum are carbide forming elements, some of which enter into solid solution in atomic state, and the other part forms replacement type Gold cementite; aluminum, copper, nickel, cobalt, silicon, etc. do not form carbide elements, generally exist in the solid solution as atoms.

There are many kinds of alloy steel, which are generally divided into low alloy steel (content < 5%), medium alloy steel (content 5% - 10%) and high alloy steel (content > 10%); according to the quality, it is divided into high-quality alloy steel and special alloy steel; according to the characteristics and application, it is also divided into alloy structural steel, stainless steel, acid resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel and rolling bearing steel Alloy spring steel and special performance steel (such as soft magnetic steel, permanent magnetic steel, non-magnetic steel), etc.
