18MnMoNbR steel plate belongs to the low-temperature pressure vessels with steel plate, is the manufacture of pressure vessels of a pressure vessel special steel plate, "18" is that the carbon content of the steel plate is 0.18%. 18MnMoNbR steel plate has a pure steel, good toughness and welding performance and other excellent features, so it can not only be used for the manufacture of pressure vessels, engineering machinery manufacturing sometimes also often use this grade of steel plate. Manufacture of pressure vessels, engineering machinery manufacturing will sometimes often use this grade of steel plate.
18MnMoNbR steel plate delivery status and implementation standards:
Delivery status: normalised + tempered, tempering temperature and not less than 650, ultrasonic flaw inspection sheet by sheet.
PS: If customers need other special delivery status, it should be specified in the contract.
Execution standard: National standard GB/T713-2014 should be implemented.
Packaging, marking and quality certificate of 18MnMoNbR: The packaging, marking and quality certificate of the steel plate shall comply with the provisions of GB/T 247.
18MnMoNbR application scope: 18MnMoNbR is used to make reactors, heat exchangers, separators, ball tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shell, liquefied petroleum gas cylinders, turbine worm shells, due to the use of petrochemicals, coal conversion, nuclear power, turbine cylinder block, thermal power, etc., the use of harsh conditions, which corrosive medium of complex large-scale equipment, such as: water washing tower, the second conversion furnace, coke Tower, desulphurisation tank, conversion gas waste heat boiler, methanation furnace, reactor, regenerator, hydrogenation reactor, methanation heater, conversion gas steam generator and other equipment and components of the construction and manufacturing projects, a large number of 18MnMoNbR or 18MnMoNbR LinHui, 18MnMoNbR (H) steel plate more than ten thousand tonnes.
