304L Stainless Hollow Bar is primarily used for the manufacture of radially machined components. The use of Hollow Bar and Mechanical Tubing is an economical and efficient means of supplying high-quality raw material and a sensible alternative to the use of solid bar as it reduces machining requirements and minimizes material wastage.
304L/1.4307 Stainless Hollow Bar is used in all sectors including; general engineering, automotive, agriculture, food, chemical, pharmaceutical and medical, etc.

304L stainless hollow bar (EN 1.4307 / AISI 304L) is an austenitic stainless steel product commonly used for radially machined components where a bore is required. Hollow bar is an efficient alternative to machining from solid bar, helping reduce machining time, minimise material wastage and improve overall cost-effectiveness for many turned parts.
Overview304L stainless hollow bar is typically selected when you need the corrosion resistance and fabrication performance of 304L, combined with the practical benefits of a pre-formed internal diameter. It is widely used across general engineering and manufacturing, and it is also suitable for many processing and hygiene-focused environments. In many cases, choosing hollow bar instead of solid bar can reduce the amount of material removed during machining, which can shorten cycle times and lower scrap.
Key benefits
Machining and fabrication notes304L is the low-carbon version of 304 and is commonly preferred for welded components because it helps reduce the risk of sensitisation in certain welding conditions. It is non-magnetic in the annealed condition, although it may become slightly magnetic after cold work. As an austenitic stainless steel, 304L cannot be hardened by heat treatment, but it can be strengthened through cold working.
Typical applications304L / 1.4307 stainless hollow bar is commonly used for bushings, sleeves, spacers, collars, rings and other radially machined components. It is used across sectors, including general engineering, automotive, agriculture, food, chemical, pharmaceutical and medical applications, depending on the operating environment and finishing requirements.
