GB713 15CrMoR pressure vessel steel plate is chromium molybdenum steel. The steel grade 15CrMoR is indicated by the letters of average carbon content and alloy elements, and the first letter of Chinese phonetic alphabet "Rong", which means “vessel”. Generally, 15CrMoR pressure vessel steel plate thickness is above 6mm but not exceed 200mm.

The delivery state of 15CrMoR pressure vessel steel plate is normalizing and tempering. The tempering temperature of 15CrMoR steel plate shall not be lower than 650℃. With the agreement of the demander, 15CrMoR steel plate thicker than 60mm can be delivered in annealing or tempering state, or delivered in the condition of accelerated cooling and tempering after normalizing.

GB713 15CrMoR pressure vessel steel plate is suitable for pressure parts of boilers and pressure vessels for medium and normal temperature service.
