Q345b precision seamless steel tubes

  Q345b precision seamless steel tubes is a high-precision steel tube after cold rolling or cold drawing; full name: cold-rolled or cold-drawn precision seamless steel tube. Because the inner and outer walls of precision seamless steel tubes have no oxide layer, high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as Cylinders or cylinders are all made of seamless tubes. The chemical composition of precision seamless steel tubes is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.

  The difference between precision seamless steel tube and seamless steel tube:

  1. The obvious difference with the seamless steel pipe is: high dimensional accuracy, which can reach 0.05mm.

  2. The surface roughness of the inner and outer diameter of the precision steel pipe is high, and the customer can directly use it without processing; and the ordinary seamless steel pipe requires the customer to perform latheing and polishing.

Q345b precision seamless steel tubes


  1. The outer diameter is smaller.

  2. High precision can be produced in small batches.

  3. The cold drawn product has high precision and good surface quality.

  4. The cross-sectional area of steel pipes is more complicated.

  5. The performance of steel pipe is superior and the metal is dense.
