20# 45# Precision Steel Pipe Astm A519 Pipe Cold Drawn
Feature:
Precision pipe is a seamless steel pipe with high precision and high brightness produced through cold drawing or cold rolling processes. Its inner and outer diameter dimensions can be precise to within 0.2mm, ensuring bending and torsional strength while also being lightweight, making it widely used in the manufacturing of precision mechanical parts and engineering structures. It is also commonly used for producing various conventional weapons, barrels, shells, bearings, etc.
We have 4 advanced hot-rolled seamless steel pipe production lines and 4 cold-drawn seamless steel pipe production lines, which can produce steel pipes of various specifications and materials.
