ASTM A387 material is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature. The thickness of A387 steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of ASTM A387 steel plate should be normalizing plus tempering or normalizing plus rapid cooling plus tempering.
By using special smelting methods, the content of phosphorus can be reduced so that ASTM A387 steel plate has high brittleness resistance and good impact toughness at low temperature.
ASTM A387 steel plate belongs to chromium molybdenum alloy steel, which 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. ASTM A387 steel plate is widely used in the manufacture of chemical fertilizer, petrochemical industry and thermal power plant equipment, such as synthetic ammonia reactor, coal gasifier, converter and hydrogenation reactor.
