14Cr1MoR Pressure Vessel Quality Steel
14Cr1MoR belongs to the pressure vessel steel plate, corresponding to the American Standard Grade SA387Gr11cl2 (ASME), which is mainly used in the fields of petrochemical industry, pressure vessel, nuclear power and so on.
Delivery status of 14Cr1MoR boiler plate: normalised + tempered, the tempering temperature of 14Cr1MoR boiler steel plate should be not less than 650℃.
14Cr1MoR pressure vessel steel plate is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed media connected to the correct large-scale equipment.

14Cr1MoR pressure vessel plate production cutting process
Production process: primary refining → LF refining → VD treatment → continuous casting (die casting) → cleaning, heating → rolling → (stacking) → surface inspection → batching → flaw detection → heat treatment → cutting samples → performance inspection → storage.
Cutting process: 14Cr1MoR pressure vessel steel plate factory inspection of the performance indicators meet the requirements in accordance with the cutting process, you can cut and processing and drawings of the material, the general thickness of the steel plate is not greater than 20mm when the priority choice of CNC plasma cutting or CNC laser cutting, if the thickness of the steel plate is greater than 30mm or more, usually choose the CNC flame cutting, you can control the precision of the cut and the time. time.
