45# Precision Seamless Steel Pipe Custom-Made

Precision steel tubes are a type of tube that is cold drawn or...Hot rolledA high-precision steel pipe material after treatment. Due to its advantages such as non-oxidized inner and outer walls, no leakage under high pressure, high precision, high luster, no deformation under cold bending, no cracks during expansion or flattening, it is mainly used to produce products like pneumatic or hydraulic components, such as cylinders, which can be seamless or welded pipes.

Precision steel tubes with high dimensional accuracy, internal and external tube surfacesSurface smoothness，Steel pipeAfter heat treatment, both the inner and outer surfaces are free of oxidation film. The steel pipes have no cracks upon expansion, flattening, or cold bending, and can withstand high pressure. They are capable of various complex deformations and mechanical deep processing treatments.

Main steel pipe grades produced: 10#, 20#, 35#, 45#, 40Cr, 42CrMo, 16Mn, etc.
