Product Description
316L Stainless Steel Honed Tube OD 20 Mm ID 16 Mm WT 2 Mm For Hydraulic Cylinders

Honed tubes are widely recognized as hydraulic cylinder tubes because they are the primary material used in the production of hydraulic cylinders. Their precision-honed inner diameter provides excellent surface finish and dimensional accuracy, ensuring smooth piston movement and reliable sealing performance. Since the honing process is mainly applied to the tube's internal bore, they are also commonly referred to as honed ID tubes or ID honed tubing.

FAQ

1. What is a 316L stainless steel honed tube?

A 316L stainless steel honed tube is a seamless precision tube that undergoes cold drawing and honing to produce a highly accurate inner diameter with an ultra-smooth surface for hydraulic and pneumatic cylinders.

2. Why choose 316L over 304 for hydraulic cylinders?

316L contains molybdenum, providing superior resistance to chlorides, seawater, and corrosive chemicals. It is the preferred choice for marine, offshore, food processing, and chemical industries.

3. What are the dimensions of this honed tube?

This product has an outside diameter of 20 mm, an inside diameter of 16 mm, and a wall thickness of 2 mm. Custom dimensions are also available.

4. What is the inner surface roughness after honing?

The honed inner surface typically achieves Ra 0.2–0.4 μm, ensuring excellent sealing performance and reduced friction.

5. Can you supply customized sizes?

Yes. JUDE STEEL offers customized OD, ID, wall thickness, length, tolerance, and machining services according to customer drawings or technical requirements.

6. What certificates do you provide?

We provide EN 10204 3.1 Material Test Certificates (MTC), PMI reports, UT reports, dimensional inspection reports, and third-party inspection certificates upon request.
