09MnNiDR: Belongs to steel plates for low-temperature pressure vessels.
"D" is the first letter of low Pinyin and "R" is the first letter of Rong Pinyin.
09MnNiDR delivery status: normalizing or normalizing + tempering, quenching + tempering - 70 degree low temperature impact.
09MnNiDR steel plate uses: used in petroleum and chemical equipment deethanizer towers, CO2 absorption towers, medium pressure flash evaporation towers, coolers, deethanizer towers, reabsorption towers, compressor casings, propane cryogenic storage tanks, etc. . Petrochemical equipment, power stations, boilers and other industries. It is used to make equipment and components such as reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum cylinders, high-pressure water pipes in hydropower stations, turbine volutes, etc.
Defects harmful to use such as cracks, bubbles, folds and inclusions are not allowed on the surface of the steel plate. There should be no delamination of steel plates.
