25CrMo4 Steel Pipe is a common Chromium Molybdenum alloy steel as per. DIN Standard. 25CrMo4 contains a lower carbon content compared with 42CrMo4. DIN 1.7218 25CrMo4 Steel will be freely machine able in the condition of HRC18-22. 25CrMo4 Steel Pipe can be used in the manufacture of the corrosive medium under carburizing and quenching condition.
