GB3531 16MnDR steel is a alloy pressure vessel steel with specified elevated temperature properties. The grades of molybdenum steel (Mo steel) and chromium molybdenum steel (Cr-Mo steel) are denoted by the average carbon content, alloy element letter and the capital letter of Chinese characters “R” pressure vessel (Rong), for instance,
15CrMoR.
Standard: GB3531
Main steel grades: q245r, Q345R, Q370R, 15CrMoR, 16MnDR, 14Cr1MoR, 13MnNiMoR, 12Cr1MoVR.
