Precision stainless steel pipe has precision, because of high precision, and good tolerance control range. The wall thickness of the precision tube is uniform, the inner wall is smooth and the surface is free from defects. The surface roughness is smoother than ordinary pipe
Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter size can be accurate to less than 0.2mm, while ensuring the same bending and torsional strength, light weight, so it is widely used in manufacturing precision machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, gun barrels, shells, bearings and so on.
Precision seamless tube is a kind of high precision steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel tubes have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. They can be seamless tubes or welded tubes. The chemical composition of precision steel pipe includes carbon C, silicon Si, Manganese Mn, sulfur S, phosphorus P and Chromium Cr.
Common materials:
The commonly used materials of precision seamless tube are 10#, 20#, 35#, 45#.
There are many materials that can be produced. As long as steel is not too hard, it can be produced basically according to needs. Such as: 10#, 35#, 16Mn, 40Cr.
