Precision seamless steel 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 dimensions can be accurate to within 0.1mm, while ensuring the same bending and torsion strength, the weight is lighter, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, shells, bearings, etc. Since the inner and outer walls of precision seamless steel pipes have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as Cylinders or oil cylinders are all made of seamless pipes. The chemical composition of precision seamless steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
Precision seamless steel pipe weight formula: [(outer diameter-wall thickness)*wall thickness)*0.02466=kg/m (weight per meter)
use:
Used in the manufacture of mechanical structures, hydraulic equipment, auto parts
