09MnNiDR pressure vessel steel Description

09MnNiDR low temperature pressure vessel steel plate belongs to low temperature steel, Grade 09MnNiDR steel under the GB3531 standard, 09MnNiDR steel tensile strength is 440-580σb/MPa, due to the addition of nickel (Ni) element in 09MnNiDR steel, the steel plate can still maintain a considerable High mechanical strength, toughness and processability. 09MnNiDR pressure vessel steel plate is mainly used in low temperature pressure vessels and other equipment. Can be used in petroleum, spherical tanks, gas storage tanks, chemical equipment deethanizers, CO2 absorption towers, medium pressure flash towers, coolers, deethanizers, reabsorption towers, compressor casings, propane cryogenic storage tanks manufacturing, etc.

09MnNiDiR pressure vessel steel plate is a low-alloy structural steel due to its low carbon content, and Mn and Ni are its main alloys. The impact temperature of 09MnNiDiR pressure vessel steel is -70 degrees, the content of nickel is required to be 0.30-0.80%, the content of phosphorus and sulfur is required to be no more than 0.020% of phosphorus and no more than 0.008% of sulfur. Since the medium to be carried is low-temperature liquid or gas, there are high requirements on the material of the pressure vessel itself, and at the same time, it must have good corrosion resistance. GB3531 09MnNiDR boiler and pressure vessel steel is delivered in normalized, or normalized and tempered delivery state, and after passing strict ultrasonic flaw detection. Beibang Steel can provide 09MnNiDiR pressure vessel steel plates of various sizes, and provide cutting and deep processing services according to customer needs to meet customer requirements.
