    Chromium molybdenum alloy steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen stripping and sulfide corrosion in the medium temperature (350-480 ℃) hydrogen environment, and has good low temper embrittlement. It is widely used in the manufacturing of chemical fertilizer, petrochemical industry and thermal power plant equipment, such as synthetic ammonia reactor, coal gasification furnace, converter and hydrogenation reactor.
     
    By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature.
     
    Sa387 material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of sa387 steel plate should be normalizing plus tempering or normalizing plus rapid cooling plus tempering.
     
    Sa387 pressure vessel chrome molybdenum alloy steel plate grade: 2.12.11.22.21.5.9.91.91l
