Description

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

Seamless stainless steel tubes for mechanical structures manufactured by Wuxi Xuanyi Stainless Steel are stainless steel pipes specially designed for mechanical equipment and engineering structure fabrication. Produced via seamless forming technology, they feature high dimensional accuracy, strong load-bearing capacity and uniform internal microstructure.

They not only possess excellent strength, corrosion resistance and machinability, but also fit multiple processing operations including welding, cutting and bending. Widely used in machinery manufacturing, auto spare parts, engineering equipment, building structures and automated equipment, they provide stable and reliable support and connection for all types of structural components.

Three Key Advantages

Tube Size Chosen Around the Finished Part

OD, ID and wall thickness are chosen with the finished component in mind, keeping the starting material closer to the dimensions required after machining.

Machining Allowance Considered Before Ordering

For parts that require turning, drilling or other machining, suitable allowance can be considered at the material-selection stage to reduce unnecessary material removal and machining work.

Cut Pieces Ready for Batch Production

Cut lengths can be prepared around component size and production batches, reducing additional material cutting before machining.

FAQ

Q: Should I give you OD and ID, or OD and wall thickness?

A: Either may be used depending on the part. If the inside diameter affects the finished component or machining allowance, providing both OD and ID is more useful.

Q: Can you cut the tubing into short pieces for machining?

A: Yes. Send us the piece length, quantity and tolerance, and we can check the cutting arrangement with the order.

Q: Can I send you my finished-part dimensions?

A: Yes. For machined components, finished dimensions are useful because they help us check whether the starting tube size leaves a reasonable machining allowance.
