Steel 37Х12Н8Г8МФБ-sh (ЭИ481-sh) is one of the complex-alloyed heat-resistant alloys of austenitic class. The steel contains 12% chromium, 8% manganese and nickel, 0.37% carbon, up to 1.5% vanadium and molybdenum, up to 0.5% niobium, as well as sulfur and phosphorus additives - a hundredth of a percent. The base is iron. The purpose of the alloying is to increase the heat and heat resistance, capability, resistance to aggressive environments. Melting of steel is carried out in an open arc furnace. Circle steel KhN68VKTU-vi is made by hot rolling and with the help of calibration - to give the products the exact outside diameter.

Technological processing

Hot deformation of semi-finished products is carried out in the temperature range of 1170 °C at the beginning of the process, and 850 °C upon completion. After deformation the steel is cooled. According to the first mode, cooling in water, oil or air is performed, and according to the second mode, cooling is performed in water, followed by holding the products for 4-4.5 hours. Welding is carried out using electrodes KTI-762.


Heat-resistant tubes and wheels 37Х12Н8Г8МФБ-sh are applied in power machine building industry (making of machines and equipment for power engineering), cellulose and paper industry and industrial chemistry. Fasteners, transitions, fittings and other parts required for installation work with a limited service life. They are designed for operation up to 600-650 °C. Seams in this case must have the same requirements for heat resistance and heat resistance, which depends not only on the choice of welding materials, but also on the welding regime and heat treatment after the end of the process.
