What are the characteristics and uses of 18MnMoNbR pressure vessel steel plate

18MnMoNbR steel plate belongs to medium and low temperature pressure vessel steel plate, executive standard: GB / T713, "18" means that the carbon content of the steel plate is 0.18%. 18MnMoNbR pressure vessel steel plate has the characteristics of purity, good toughness and welding performance, so it can not only be used in the manufacture of pressure vessels, but also in the manufacture of construction machinery.

18MnMoNbR pressure vessel steel plate is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure vessel, liquefied petroleum gas cylinder and turbine volute. Due to the harsh service conditions of petrochemical industry, coal conversion, nuclear power, steam turbine cylinder, thermal power, etc., the construction and manufacturing of large equipment and components with complex corrosive medium, such as water scrubber, second shift converter, coke tower, desulfurization tank, conversion gas waste heat boiler, methanation furnace, reactor, regenerator, hydrogenation reactor, methanation heater, conversion gas steam generator, etc. In those projects, 18MnMoNbR or 18MnMoNbR (HIC) and 18MnMoNbR (H) steel plates are widely used.

Delivery status and executive standard of 18MnMoNbR pressure vessel steel plate:
Delivery status: normalizing + tempering, tempering temperature not lower than 650℃, ultrasonic flaw detection shall be carried out one by one.
