Technical characteristics

Steel 12H13 martensitic-ferritic heat-resistant, heat-resistant and corrosion-resistant. It is composed of carbon and 0.12%, as alloying elements — chrome-12−14%, silicon, manganese, Nickel. The purpose of steel — the details of increased plasticity, can withstand vibration and shock loading up to a temperature of 450−500°C and at normal temperatures contact with slightly aggressive environments. Is strip, sheet, round, wire, tube. The doping increases the heat resistance and enables to produce the steel parts to the power type. This brand has a relatively balanced performance of heat resistance and heat resistance, making it very popular. When choosing heat-resistant steel, if not burdened working conditions, it is possible to change this brand to another, with lower carbon content. Substitute this steel is brand 20X13.

The use of martensitic-ferritic steels depends on the operating conditions. Ferritic alloys capable of withstanding prolonged heating to t° to 600 °C. Their klassificeret as heat resistant alloys. High temperature more than 600 °C require the use of austenitic heat-resistant steel. In accordance with GOST, intensive scale formation in air starts at a temperature of more than 1050 °C.


Round 12H13 manufactured by stamping metal under a predetermined shape. The temperature quenching of the rod 1050−1150°C in air. This alloy is weldable is limited. Welding method: submerged arc ADS, RDS, CBS, ARDS. Heat and a final heat treatment is used, depending on the method and type of welding and the appointment of a welded design. Made of seamless pipe — seamless or welded — welded. Depending on the type of surface of the pipes, they may be referred to in catalogs as mirror (polished), polished or matte.
