20# precision steel pipe
20# precision steel tube is a high-precision steel tube material processed by cold drawing or hot rolling. Because 20# precision steel pipe has no oxide layer on the inner and outer walls, bears high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, etc., it is mainly used to produce pneumatic or hydraulic components, such as The cylinder or oil cylinder can be a seamless tube or a welded tube. The chemical composition of precision steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
The production process of precision steel pipes is the same as that of ordinary seamless pipes, except for the final pickling and cold rolling process.

use:
Automobiles, machinery parts and other machinery that have high requirements on the precision and smoothness of steel pipes. The current users of 20# precision steel pipes are not only users who have relatively high requirements for precision and smoothness. Because the precision of the precision bright pipe is high and the tolerance can be maintained at 2-8 wire, many machining users are in order to save labor, material and time. The loss of seamless steel pipe or round steel is slowly turning into precision bright pipe.
