11MnNiMoDR is a low-temperature pressure vessel steel plate, widely used in the manufacture of petroleum, chemical equipment and de-ethanisation towers, petroleum storage tanks, medium-pressure flash evaporation towers, coolers, and other low-temperature pressure vessels. 11MnNiMoDR steel grades have two digits to indicate that the average carbon content of 11, the alloying elements indicated by the symbols of the alloying element letters MnNiMo - Indicates the manganese nickel molybdenum alloy element letters, low-temperature pressure vessels, "low" and "capacity" of the initial letters of the hanyu pinyin "DR" composition.
11MnNiMoDR low-temperature container plate of the implementation of the standard: GB/T 713.3-2023, the standard in March 2024 began to implement the 11MnNiMoDR is the standard new grade.
11MnNiMoDR low temperature container plate performance analysis: 11MnNiMoDR steel plate heat treatment process includes quenching and tempering treatment, this treatment process can improve the hardness and strength of the steel plate, while maintaining good toughness and plasticity. In addition, 11MnNiMoDR steel plate has good weldability and machinability, which is convenient for welding and machining operations during the manufacturing process.
11MnNiMoDR steel plate application: 11MnNiMoDR steel plate has good comprehensive performance, so it is widely used in petroleum, chemical, electric power, aerospace and other fields of low-temperature pressure vessel manufacturing, such as reactors, heat exchangers, tanks and so on.
