Steel grade 20Х3МВФ (ЕИ415) is a heat-resistant iron-based alloy. The composition is alloyed with 3% chromium, molybdenum, tungsten and vanadium additives. In addition the alloy contains 0.2% of carbon, a hundredth of a percentage of silicon, sulfur and phosphorus Forging metal is made in a temperature range from 1150-1180 degrees in the beginning to 850 degrees at the end ... The recommended temperature hardening of semi-finished products (in air or water) to not more than 1200 degrees. The bars of this alloy are hardened at t° around 1050-1150°C in air.

Production of slotted kiln rollers for rapid firing of ceramic tiles, household flat ceramics and other ceramic products. Thin wire is used in furnace conveyor grids. Tubes 20X3MVF withstand temperatures of 1250-1300 degrees and can be applied for parts of burners, covers thermoelectric converters. This alloy does not contaminate thermocouple electrodes and provides reliable protection for the wire thermocouple when working in hazardous conditions.

Heat-resistant 20Cr3MvF steel can operate under load at high temperatures. It is resistant to corrosion in air and gas environments when heated and is used as a structural material for internal combustion engines, gas and steam turbines, nuclear power plants and jet engines. The high heat resistance is dependent on two main factors: the strong bonds between the atoms of steel and the structure of the substance. Pipes 20Х3МВФ are plastic enough that it is possible to build chimneys and other pipe systems at any angles. The metal has an attractive surface and does not need a protective coating.
