Stainless Steel Hollow Bar

Stainless steel hollow bar is a corrosion-resistant tubular bar used for shafts, sleeves, valve bodies, mechanical parts, and structural fabrications that need strength with lower weight and less machining waste than solid bar. For buyers who need machinability, dimensional consistency, and export-ready supply, hollow bar is often a more efficient choice than drilling a solid round bar.

• Common grades: 304/304L, 316/316L, 321, 310S, and duplex options subject to mill availability
• Supply options: custom outside diameter, wall thickness, cut lengths, surface finishing, and export packing
• Typical uses: hydraulic cylinders, bushings, pump and valve parts, rollers, offshore and chemical equipment

Baoli Steel supplies stainless steel hollow bar for fabrication shops, OEM buyers, and project contractors that need stable quality and practical lead times. We can help match the grade, outside diameter, wall thickness, and processing route to your service conditions, whether the requirement is corrosion resistance, higher temperature performance, or better strength-to-weight efficiency.

Stainless steel hollow bar is also a practical choice when downstream machining matters. Because the center bore is already formed, manufacturers can reduce drilling time, lower material removal, and improve overall production efficiency for precision parts and welded assemblies.
