Description
🟦 Product Overview
S355 Honed Tube is a precision‑finished seamless steel tube designed for hydraulic and pneumatic cylinder applications. Manufactured from S355 structural steel, it offers excellent mechanical strength, dimensional accuracy, and surface finish.
The inner surface is honed or skived & roller‑burnished to achieve a mirror‑like finish, ensuring smooth piston movement and extended seal life.
🟦 Key Features
- High strength and toughness (S355 grade)
- Excellent internal surface finish (Ra ≤ 0.4 μm)
- Precise dimensional tolerance (H8 / H9)
- Suitable for hydraulic and pneumatic cylinders
- Long service life and low friction performance
🟦 Standards
- EN 10297‑1 (Seamless Circular Tubes for Mechanical and General Engineering Purposes)
- EN 10305‑1 (Precision Steel Tubes – Seamless Cold Drawn)
- DIN 2391 / ISO 4394
- ASTM A519 (Equivalent Standard)
