FAQ

1. What is a 304 stainless steel honed tube?

A 304 stainless steel honed tube is a precision seamless tube processed by cold drawing and honing to achieve a smooth inner surface and accurate dimensions for hydraulic cylinder applications.

2. Why is honing required for hydraulic cylinder tubes?

Honing creates a smooth and precise inner bore that reduces friction, improves sealing performance, and extends the working life of hydraulic cylinders.

3. What is ASTM A269 used for?

ASTM A269 is a standard specification for seamless and welded austenitic stainless steel tubing used in general corrosion-resistant and industrial applications.

4. What is the difference between 304 and 316L honed tubes?

304 stainless steel provides excellent general corrosion resistance, while 316L contains molybdenum for improved resistance in marine and chemical environments.

5. Can you supply custom hydraulic cylinder tubes?

Yes. JUDE STEEL supplies customized OD, ID, wall thickness, length, tolerance, and surface requirements according to customer drawings.

6. Do you provide material certificates?

Yes. We provide EN10204 3.1 Material Test Certificates (MTC), inspection reports, and third-party certificates upon request.
