15MnNiNbDR steel plate meets the manufacturing needs of low temperature spherical tanks

The comprehensive properties of the 15MnNiNbDR steel plate are good, and it can fully meet the manufacturing needs of -50℃ low temperature spherical tank.

15MnNiNbDR boiler steel plate has good strength and plasticity, and steel plates of different thicknesses have good low temperature toughness.

15MnNiNbDR steel plate has a lower non-plastic transition temperature and higher fracture toughness.

The strain aging sensitivity of 15MnNiNbDR steel sheet is low, which provides a good precondition for the cold working of spherical tank.

After SR treatment of 15MnNiNbDR steel plate, the lower yield strength and tensile strength of the steel plate decreased slightly, and the plasticity, toughness, non-plastic transition temperature, fracture toughness and metallographic structure did not change greatly, which can meet the requirements of stress relief heat treatment after spherical tank installation.
