S31803  Duplex Small Diameter Pipe

Description

S31803  Duplex Small Diameter Pipe

Pipe Profile 

S3180 precision tube is a high-precision, high-brightness seamless steel pipe produced by cold drawing or cold rolling. The inner and outer diameter dimensional tolerances can be accurate to within 0.2mm. When the bending and torsional strength are the same, the weight is light, so it is widely used in the manufacture of medical instruments, precision mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells, bearings and so on.
