Precision steel tube bright pipe high precision seamless steel pipe finishing rolling oil pipe
Precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation during cold bending, no expansion, flattening and no crack, it is mainly used to produce pneumatic or hydraulic components, such as air cylinder or oil cylinder, which can be seamless pipe or welded pipe.

1045 S45C C45 45# Seamless steel tubes for structural purposes machining
No.45 steel is high quality carbon structural steel with low hardness and easy cutting. It is often used as template, pin and guide post in mould, but it needs heat treatment. Recommended heat treatment temperature: normalizing 850, quenching 840, tempering 600. The content of carbon (c) in its chemical composition is 0.42-0.50%, Si content is 0.17-0.37%, Mn content is 0.50-0.80%, Cr content is less than 0.25%.
