Hydrogen-resistant steel 14Cr1MoR boiler plate

Hydrogen-resistant steel 14Cr1MoR boiler plate production process: during the production of 14Cr1MoR steel plate, strictly control the fluctuation range of chemical composition, strictly control P, S, Sn, Sb, As, Cu and other harmful elements, reduce the tendency of cold embrittlement and temper embrittlement, and improve the corrosion resistance of steel. The reasonable bainite tempering structure and grain size can be obtained by controlling temperature rise, strictly controlling temperature rise and heat treatment process, and the comprehensive properties of the 14Cr1MoR steel can be improved.

Hydrogen-resistant steel 14Cr1MoR smelting method: adopting the smelting process of electric furnace + external refining and vacuum degassing, the secondary ESR smelting can be carried out. The 14Cr1MoR steel plate shall be essentially fine grain killed steel.

14Cr1MoR boiler plate is used to manufacture large-scale equipment with high temperature and high pressure and in contact with hydrogen or hydrogen mixed medium, such as petrochemical, nuclear power, steam turbine cylinder, thermal power, etc.
