Introduction of steel plate grades for 12Cr1MoVR pressure vessels

12Cr1MoVR is a steel plate for boilers and pressure vessels, which is usually delivered in a normalized condition. 2Cr1MoVR boiler and pressure vessel steel plate implements GB713-2014 standard. 12Cr1MoVR steel plate is suitable for: petrochemical, nuclear power, steam turbine block, thermal power and other large equipment with high temperature and high pressure, and hydrogen or hydrogen mixed media. 12Cr1MoV steel plate has higher oxidation resistance and thermal strength. The creep limit of this steel is close to the durability strength value and has high plasticity in the case of durable tensile. It is a widely used steel grade for boiler superheaters, headers and main steam ducts of high-pressure, ultra-high-pressure and subcritical power stations.

(2): The formula for calculating carbon equivalent (CE) is as follows: CE=C+Mn/6+(Cu+Ni)/15+(Cr+Mo+V)/5.

12Cr1MoVR is used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, liquefied petroleum cylinders, water turbine volutes, due to the harsh conditions of petrochemical, coal conversion, nuclear power, steam turbine cylinder block, thermal power and other use conditions, among which the corrosion medium complex large-scale equipment such as: water washing tower, second conversion furnace, coke tower, desulfurization tank, reforming gas waste heat boiler, methanation furnace, reactor, regenerator, hydrogenation reactor, methanation heater, In the construction and manufacturing projects of equipment and components such as reforming gas steam generators, a large number of 12Cr1MoVR or 12Cr1MoVR hydrogen,
