25CrMo4 Seamless Steel Tube

Advantages of 25CrMo4 Seamless Steel Tube

25CrMo4 alloy structural steel is a German high-temperature pressure vessel steel with material number 1.7218. 25CrMo4 steel has high hardebability, no tempering brittleness, good welding performance, and good cold strain plasticity.

One of the key advantages of 25CrMo4 seamless steel pipe is its high strength, which allows it to withstand large loads and not easy to deformation or damage. According to industry standards, the tensile strength of 25CrMo4 seamless steel pipe is around 600Mpa , making it a suitable choice for demanding applications.

In addition to its high strength, 25CrMo4 seamless steel tube also exhibits excellent high temperature resistance, making it a ideal choice for use in high temperature environments, such as power plants, chemical industry, and oil refineries, etc.

Furthermore, 25CrMo4 seamless steel tube has a high melting point, which ensures that it remains stable and reliable even under extreme conditions. Its melting point is around 1420℃, ensuring that it can handle high temperature application without any issues.
