15CrMoR

15CrMoR vessel steel plates belong to medium temperature hydrogen resistant steel. The number "15" respect 0.15% carbon content. When the temperature is below 550℃, 15CrMoR vessel steel plates have high endurance strength.BBN Steel's rolling range is thickness within 3-150mm.

15CrMoR Steel Plate Specification:

Thickness: 3mm to 150mm,Width: 1500mm to 4000mm,Length: 3000mm to 15000mm
