Production
Brand 20h3mvf steel (ЕИ415) is a heat-resistant alloy based on iron. Composition alloyed with chromium in an amount of 3%, additives of molybdenum, tungsten and vanadium. Additionally, the alloy contains 0.2% carbon, some hundredths of a percent of silicon, sulfur and phosphorus metal Forging is performed in temperature range of 1150−1180 degree first and to 850 degrees at the end… recommended temperature of quenching of semi-finished products (in air or in water) not more than 1200 degrees. Bars of this alloy are hardened at a temperature of about 1050−1150°C in air.

Use
The production of commercials slot furnaces for fast firing ceramic tiles, flat household ceramics and other ceramic products. A thin wire is used in conveyor oven grids. Pipe 20KH3MVF withstand the temperature of 1250−1300 degrees, can be used for parts 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.

20KH3MVF heat-resistant steel can work under load at high temperatures. It is resistant to corrosion in air and gas environments, when heated, is used as a structural material for internal combustion engines, gas and steam turbines, atomic power plants, jet engines. High-temperature strength is dependent on two main factors: the strong bonds between the atoms of steel and the structure of matter. Pipe 20KH3MVF very flexible, allowing you to build chimneys and other pipe systems at any angle. Metal has an attractive surface and needs no protective coating.
