Description

Wuxi Xuanyi Stainless Steel Co., Ltd. is one of the leading manufacturers and suppliers of stainless steel hollow bar in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk stainless steel hollow bar made in China here from our factory.

The stainless steel hollow bars produced by Wuxi Xuanyi Stainless Steel are hollow circular profiles made of stainless steel as raw material through processes such as perforation, hot rolling, or cold processing, which have both high strength and light weight. It has excellent corrosion resistance, good mechanical and processing properties, and can reduce material consumption while ensuring structural strength. It is widely used in fields such as mechanical manufacturing, petrochemicals, energy equipment, shipbuilding, and precision machining.

Three Key Advantages

Pre-Formed Bore Reduces Drilling & Boring

The hollow section already includes a central bore, reducing the drilling and boring required when producing sleeves, bushings and other components with an internal opening.

OD & ID Selected Around the Finished Part

Both the outside diameter and inside diameter can be selected around the required component dimensions, allowing the starting stock to more closely match the final part geometry.

Ready Hollow Stock for Ring & Sleeve Blanks

A continuous hollow bar can be cut into multiple ring, sleeve or bushing blanks with the central opening already in place, making it practical for repeated component production.

Application Of Bar

Machinery Manufacturing

It is used to machine shafts, pin shafts, fasteners, transmission parts and various mechanical components to meet high strength and wear resistance standards.

Petrochemical Industry

Applied to valves, pipe fittings, pump bodies and chemical equipment, it adapts to corrosive media and complex working conditions.

Ship & Marine Engineering

Widely utilized for ship structural parts, offshore platform equipment and seawater delivery systems. With outstanding corrosion resistance, it effectively resists corrosion caused by high humidity and high salinity environments and extends equipment service life.

Xuanyi Factory

Stainless Steel Hollow Bar Supply Support

1. Machining Allowance Reviewed Before Material Selection
For hollow-bar components, we can review the required machining allowance on both the outer and inner surfaces before confirming the starting material, helping avoid selecting stock that leaves insufficient material for final machining.

2. Trial Material Available for Machining Verification
For parts with demanding machining requirements, trial material can be prepared before a larger order so the customer can verify machining behavior and finished-part results first.

3. Residual Wall Considered After Final Machining
For components machined on both the OD and ID, we consider the remaining wall after material removal rather than looking only at the original hollow-bar dimensions, helping customers evaluate whether the selected stock is practical for the finished part.

FAQ

Q: What does eccentricity mean in stainless steel hollow bar?

A: Eccentricity refers to the difference between the center of the outside diameter and the center of the bore. It can result in uneven wall thickness around the circumference, so it should be considered when the finished component requires a consistent wall after machining.

Q: How is the wall thickness of a stainless steel hollow bar determined?

A: The nominal wall thickness is based on the difference between the outside diameter and inside diameter. However, actual wall thickness can vary within the applicable dimensional tolerances, so critical machining projects should not rely on the nominal wall value alone.

Q: Can stainless steel hollow bar be used instead of a forged ring?

A: For some machined ring components, hollow bar can be cut into ring blanks and used as the starting material. However, if the drawing, standard or service condition specifically requires a forged ring, hollow bar should not be treated as a direct substitute.
