Technical characteristics

Steel 12Х13 of martensitic-ferritic class is heat-resistant, heat-resistant and corrosion-resistant. Its composition includes carbon-0,12%, as alloying elements - chrome-12-14%, silicon, manganese, nickel. Steel purpose - details of high ductility sustaining vibration and shock loads up to 450-500°С, and at normal temperature contact with slightly aggressive medium. Ribbon, sheet, circle, wire, pipe are produced. Alloying increases heat resistance and makes it possible to produce parts for power-type installations from this steel. This grade has balanced characteristics regarding heat resistance and heat resistance, which makes it very popular. When choosing heat-resistant steel, in case of unstable working conditions, this steel grade can be exchanged for another one with a lower carbon content. The substitute for this steel is grade 20X13.

Percentage composition of 12X13 (GOST 5632-72)

C Si Cr Cu Mn Ni Ti S P Fe

The application of martensitic-ferritic steels depends on the operating conditions. Ferritic alloys can withstand prolonged heating up to t° 600 °C. They are classified as heat resistant alloys. High temperatures above 600 °C require the use of austenitic heat-resistant steel. According to GOST, intensive scale formation in the air environment begins at temperatures above 1050 ° C.


Circle 12X13 is made by stamping the metal under a certain given shape. The hardening temperature of the rod 1050-1150 ° C in the air. This alloy is limited weldable. Welding method: ADS under flux, RDS, CTS, ArDS. Heating and final heat treatment is used depending on the method and type of welding and the purpose of the welded structure. Pipes may be seamless - solid drawn or welded - electrically welded. Depending on the type of surface of the pipe, they may be designated in catalogs as mirror (polished), brushed or matt.
