15MnNiDR Steel Description

15MnNiDR low-temperature vessel steel plate belongs to low-alloy steel plate for low-temperature pressure vessel, and 15MnNiDR under the GB3531 standard. 15MnNiDR steel plate has high strength, high toughness, fatigue resistance, impact resistance, fatigue resistance, corrosion resistance, easy processing and other high-quality properties. 15MnNiDR is a plate for low temperature pressure vessel under -45. 15MnNiDR pressure vessel plate can be widely used in petroleum, chemical, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks , liquefied steam tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, turbine volutes and other equipment and components.

15MnNiDR boiler and pressure vessel steel plate has good low temperature impact toughness, excellent welding performance and resistance to hydrogen sulfide stress corrosion. Mn is the chemical element manganese, Ni is the chemical element nickel, Nb is the chemical element niobium, D is the low temperature, and R is the pressure vessel plate. GB3531 15MnNiDR pressure vessel steel is usually delivered in normalized, normalized + tempered state, and flaw detection can be done according to customer needs. We can provide 16MnDR pressure vessel steel in different sizes, and can provide cutting and deep processing services to meet the needs of different customers.
