What is the material of 11MnNiMoDR, 11MnNiMoDR steel plate is rolled in a fixed manner, and 11MnNiMo

11MnNiMoDR is a steel plate for cryogenic pressure vessels, and the impact temperature is: -70°C. Implement GB713-2014 standard. The suffix "R" in the grade refers to the pinyin initial letter of the pressure vessel "Rong", 11 indicates that the carbon content is 0.11%, and the Mn, Ni and Mo in the grade indicate that the content of chemical elements manganese, nickel and molybdenum is higher, and the 11MnNiMoDR steel plate adopts oxygen top blowing converter method, open-hearth furnace method or smelting in electric furnace. Other equivalent methods may also be used in consultation with the demander.

Carbon is one of the main elements of 11MnNiMoDR steel plate, which can improve the hardness and strength of the steel plate, but too much carbon will reduce the toughness and weldability of the steel plate. Silicon can improve the strength and toughness of steel plates, and is often used as a deoxidizer in the manufacturing process. Manganese is an important alloying element that can improve the strength and heat resistance of steel plates. Phosphorus and sulfur have less effect on the steel plate, but too much phosphorus and sulfur will reduce the machinability and weldability of the steel plate.

11MnNiMoDR steel plate has high strength, low temperature resistance, impact resistance, wear resistance, corrosion resistance, fatigue resistance, high toughness, compressive resistance and easy welding and processing.

11MnNiMoDR 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 steam drums.
