16MnDR Pressure Vessel Steel
16MnDR boiler steel plate is a kind of low-temperature pressure vessel steel plate, the executive standard: GB3531. 16MnDR pressure vessel plate plate signifies: 16Mn indicates that the carbon content of the steel plate is about 0.16%, D indicates that it is low-temperature, and R indicates that it is a pressure vessel.
16MnDR vessel steel plate is mainly composed of elements such as manganese, carbon, and silicon, as well as small amounts of impurities such as phosphorus and sulfur. Due to its excellent low-temperature resistance and mechanical properties, 16MnDR boiler steel can still maintain good toughness and strength in low-temperature environments, and can withstand large pressure and impact forces. 16MnDR pressure vessel quality steel is widely used in the manufacturing of pressure vessels in fields such as petroleum, chemical, and natural gas.
