25CrMo4 alloy steel pipe properties

25CrMo4 alloy steel pipes have specific high temperature properties, with good plasticity, toughness, cold bending properties and welding performance.

25CrMo4 high hardenability, no temper brittleness, welding is quite good, the tendency to form a cold crack is very small, machinability and cold strain plasticity is good.

Generally used in quenching or carburizing quenching state, 25CrMo4 alloy steel used in the manufacture of non-corrosive media and

the working temperature is lower than 250 ℃, containing nitrogen and hydrogen mixture of medium work in the high-pressure pipe and a variety of fasteners
