37KH12N8G8MFB - эи481 sheet, round, wire
Brand 37KH12N8G8MFB-sh (ЕИ481-W) is a heat-resistant alloy based on iron, is composed of components such as chromium (11−13%), Nickel and manganese (about 8%),). In addition, this Nickel-chromium alloy includes additives (1%) of such elements as molybdenum, vanadium and niobium. The composition is carbon of 0.37%, hundredths of a percent of silicon, phosphorus and sulfur. The alloy is melted in open electric arc furnaces. Semi rashwood at temperature of 1150−1180 degree first up to 850 degrees at the end of processing. Tubes and rods are hardened at t° 1050−1150 in the air.

This steel grade, as most high-temperature alloys are difficult to weld. To obtain high quality connection requires additional steps: heating up to 200−300 degrees and a final heat treatment after welding. Fastening of structural parts and components made by manual arc welding.
Pipe and round due to the heat resistance and the heat resistance are used for the manufacture of parts of high temperature furnaces, parts of internal combustion engines, turbojet engines. The resistance is dependent on: a strong link between atoms and structure of matter. High chemical and corrosion resistance allows to use the alloy in the petrochemical industry. Low Nickel content make products from this alloy is resistant to sulfurous environment. A thin wire is used in conveyor oven grids. Pipe 37KH12N8G8MFB-sh can be used as the details of burners, covers thermoelectric converters. This alloy does not contaminate the electrodes thermocouples and provides reliable protection of the thermocouple wire when working in hazardous conditions. Such pipes can withstand the temperature of 1250−1300 degrees. They are used as chimneys for discharging the products of combustion of industrial and domestic furnaces.
