Q345R Pressure Vessel Steel Plate
Q345R vessel plate, a boiler vessel plate, is widely used in petroleum, chemical, power station, boiler and other industries, generally used to make reactors, heat exchangers, separators, gas guides, liquefied gas tanks, boiler gas packages and liquefied petroleum gas cylinders.
Q345R: Q-"Qu" the first letter of hanyu pinyin, 345- yield strength value, R: "Rong" the first letter of hanyu pinyin.
Q345R is an ordinary low alloy steel, is commonly used in boiler pressure vessel steel.
Q345R boiler steel plate performance and Q345 steel boiler plate (16Mn) (16mm steel plate yield strength greater than 345Mpa) performance is similar to the tensile strength of (510-640) between the elongation is greater than 21%, zero-degree V-impact work is greater than 34J. Q345R pressure vessel plate process reference standard GB713-2014.
