15MnNiNbDR belongs to the steel plate is a low temperature pressure vessel with container class, 15MnNiNbDR Dance Steel Steel Plate is the impact temperature of minus -45 °, with high strength, high toughness characteristics, 15MnNiNbDR steel plate appeared to fill the industry low-temperature containers with low alloy steel plate of minus 40 degrees between minus 70 degrees in the use of steel blanks, commonly used in the manufacture of low-temperature pressure vessels, low-temperature Spherical tanks, high-parameter low-temperature cylindrical vessels, low-temperature ethylene spherical tanks and other equipment. Especially the low-temperature container plate of WISCO, good performance, the same impact temperature performance to maintain a good performance.
15MnNiNbDR executive standard: the implementation of the national standard GB/T 3531 standard.
Delivery state of 15MnNiNbDR: the general delivery state is normalised + tempered. ps: if customers need other special delivery state should be specified in the contract.
Chemical composition of 15MnNiNbDR (melting analysis %):
C: less than or equal to 0.180
Si: between 15-0.50 Mn: between 1.20-1.60
P: less than or equal to 0.020S: less than or equal to 0.010

15MnNiDR steel plate for cryogenic vessel is widely used in manufacturing cryogenic welded pressure vessels. The steel plate for cryogenic pressure vessels produced by Dancing Steel has pure steel, low inclusions, excellent performance, good strength and toughness and low temperature toughness, which fully meets the standard requirements, especially the low-temperature impact toughness, which is much higher than the standard requirements.
