The main classification of precision bright seamless steel tube is precision seamless steel tube, precision hydraulic seamless steel tube, cold drawn precision seamless steel tube, cold rolled precision seamless steel tube, high precision seamless steel tube, precision bright seamless steel tube. Precision steel pipe is a kind of precision steel pipe due to no oxidation layer on the inner and outer wall, no leakage when bearing high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening without cracks, etc. The main features of precision bright seamless steel pipe are smaller outer diameter, high precision, high accuracy, good surface quality, superior performance, and denser metal. There are strict tolerances and roughness for the inner hole and outer wall size of the tube body with and strict requirements. Mainly used in the manufacture of mechanical structures, hydraulic equipment, hydraulic and pneumatic cylinders.

It is a chromium-free multi-element bainite type hot strength steel. Although the steel does not contain chromium, but due to the combined effect of multiple elements, the steel has high thermal strength, oxidation resistance and organizational stability. It can be used as a boiler superheater tube with a service temperature of 580℃, and can also be used for pressure vessels, etc.
