Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Alloy 20 Socket Weld Fittings, where the alloying elements tend to form either solid solutions or compounds or carbides. Alloying elements in our Alloy 20 Forged Socket Weld Elbow Fittings as well have an effect on the eutectoid temperature of the steel. Manganese and nickel in these Alloy 20 Forged Socket Weld Tee Fittings lower the eutectoid temperature and are known as austenite stabilizing elements. With enough of these elements, the austenitic structure of our Alloy 20 Forged Socket Weld Cross Fittings may be obtained at room temperature.
Carbide – forming elements raise the eutectoid temperature in these Alloy 20 Forged Socket Weld Cap Fitting, where these elements are as well-known as ferrite stabilizing elements. Deposition of complex and heavy organic compounds in our Alloy 20 Forged Socket Weld Union Fittings in crude and heavy oil can cause a number of severe problems up to pipeline blocking.
These Alloy 20 Forged Socket Weld Plug Fittings are developed for energy – related applications involving oil & gas drilling and as a result are subjected to stresses in machine parts. Further, our Alloy 20 Forged Socket Weld Lateral Tee Fittings is also used in domestic, professional or industrial areas. This specification covers nominal wall and minimum wall seamless ferrite these Alloy 20 Forged SW Cap Fittings intended for high temperature service.
