Precision seamless steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, they can withstand high pressure without leakage, have high precision, high smoothness, no deformation during cold bending, and no expansion. The chemical composition of precision steel pipes is C, Si, Mn, S, P, and Cr, compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsional strength are the same. It is an economical cross-section steel widely used in manufacturing structural and mechanical parts.

Commonly used materials for precision seamless steel pipes are 10#, 20#, 35#, and 45#. Many materials can be produced. As long as steel is not too hard, it can be produced according to needs. Such as: 10#, 35#, 16Mn, 40Cr.

Performance and characteristics of precision seamless steel pipe
Main features: The inner and outer walls of the steel pipe have high precision and high smoothness. After heat treatment, the steel pipe has no oxidation layer and the inner wall is highly clean. The steel pipe can withstand high pressure, does not deform during cold bending, has no cracks in flaring and flattening, and can be used for various complex operations. Deformation and mechanical processing. Steel pipe color: white with bright color, high metallic luster.
Main uses: steel pipes for automobiles, and users with high requirements for the precision and smoothness of steel pipes.

Precision seamless steel pipes generally have two processes: cold drawing or cold rolling
1. The steel pipe drawn out through the cold drawing process undergoes various high-precision treatments to form a steel pipe called cold-drawn precision seamless steel pipe.
2. The steel pipe pulled out through the cold rolling process undergoes various high-precision treatments to form a steel pipe called cold-rolled precision seamless steel pipe.

Generally speaking, whether it is cold-drawn precision seamless steel pipe or cold-rolled precision seamless steel pipe, this kind of precision steel pipe has high precision, a smooth surface, and no oxide layer on the inner and outer walls. This kind of high-precision seamless steel pipe can be Production, in hydraulic cylinders and other products.
