34CrMo/34CrMo4 Seamless Steel Tube

We are supplying thin wall thickness seamless steel pipe by material 34CrMo/34CrMo4.

This kind of pipe is widely used for making gas cylinder.

34CrMo steel gas cylinders are specialized steel cylinders manufactured with stringent specifications. These requirements typically include a lower carbon content and strict control over sulfur and phosphorus contents to ensure the material achieves high strength while maintaining excellent toughness and impact energy. Additionally, these cylinders undergo 100% non-destructive testing to guarantee their integrity and safety.

Applications of 34Crmo,34Crmo4,35Crmo Seamless Alloy Steel Tube

These materials are utilized in critical structural components that operate under high pressure, including gas cylinder pipes, vehicle transmission parts, and engine components. They are also essential in the manufacture of turbogenerator rotors, spindles, heavy-duty drive shafts, and large cross-section parts, where reliability and durability under stress are paramount.
