Stainless steel hollow bar, also known as stainless steel circular seamless tubes, intended for the manufacture of engineering components by machining.
Stainless steel hollow bar are distinguished from seamless fluid-carrying tubes or hollow sections by their dimensions and metallurgical properties which confer machinability, suitability for heat treatment and a surface condition suitable for final machining of the component.
Wuxi Cepheus is a leading manufacturer and supplier of hollow bar. We can produce stainless hollow bar in 4mm to 1219mm diameter.
The maximum length of stainless steel hollow bar we manufacture is up to 18m. All stainless hollow bar can be cut to size. Sheye Metal also supplies stainless hollow bars with polished finish.
We can polish the hollow bar into 8K finish (mirror finish). Brushing finish, 200 to 600 Grit finish are also available to us. PMI testing for hollow bar is for free in Wuxi Cepheus. For Metal, we are serious.
