Excellent quality Square Tube Galvanized - Cold rolled precision seamless steel pipe – Hongmao
Excellent quality Square Tube Galvanized - Cold rolled precision seamless steel pipe – Hongmao Detail:
Product Introduction
Precision seamless steel pipe is a kind of high-precision steel pipe processed by cold rolling or cold drawing; full name: cold rolled or cold drawn precision seamless steel pipe. Since the inner and outer walls of precision seamless steel pipes have no oxide layer, withstand high pressure without leakage, high precision, high smoothness, 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.
