37H12N8G8MFB co-Tube circle
Brand 37H12N8G8MFB-w (w-EI481) is a superalloy based on iron, is composed of components such as chromium (11−13%), nickel and manganese (about 8%)). In addition, the nickel-chromium alloy comprises additive (1%) of elements such as molybdenum, vanadium and niobium. As a part of — 0.37% carbon, hundredths of a percent of silicon, phosphorus and sulfur. The alloy is melted in open electric arc furnaces. Semis Raskova at a temperature of 1150−1180 degrees to 850 degrees at the beginning at the end of treatment. Pipes and rods hardened at t ° 1050−1150 on the air.

This type of steel, like most heat-resistant alloys are difficult to weld. To obtain high-quality connections require additional steps: heating up to 200−300 degrees and final heat treatment after welding. Bonding of structural parts and components produced by manual arc welding.

Pipe and terms of heat resistance and heat resistance due to used for the manufacture of high-temperature kilns mounting parts, fragments of internal combustion engines, turbo-jet engines. Heat resistance is dependent on: the strong bonds between the atoms of steel and the structure of matter. High chemical and corrosion resistance allow the use of the alloy in the petrochemical industry. Low nickel content of products made of this alloy resistant to sour environment. A thin wire is used in the oven conveyor grids. Pipes 37H12N8G8MFB-w can be used as a burner parts, covers of thermoelectric converters. This alloy does not pollute the electrodes thermocouple and it provides reliable protection of the thermocouple wire when working in hazardous conditions. These pipes can withstand the temperature of 1250−1300 ° C. They are used as chimneys for discharging the products of combustion of industrial and household stoves.
