316/316L Stainless Steel Honed Tube
2205 Duplex Stainless Steel Honed Tube
Engineered Corrosion Resistance & Precision Bore Quality
Designed to eliminate cylinder bore corrosion, seal erosion, and downtime in offshore, chemical, and fluid-handling machinery.
High Corrosion & Pitting Resistance
Premium stainless alloys (304, 316L, 2205) protect internal bores against salt spray, marine splash, and harsh chemical exposure.
Precision Bore Finish & Galling Prevention
Smooth, controlled internal surface roughness (Ra 0.2–0.4 µm) reduces piston friction, prevents seal wear, and minimizes material galling.
High Yield Strength & Pressure Stability
Strict cold-drawing and honing controls ensure consistent wall thickness and high bursting strength under operating hydraulic pressure.
Controlled Stainless Machining & Quality Audit
From alloy verify inspection to specialized honing techniques that maintain surface passivity and dimensional precision.
WHY CHOOSE EAST AI
Stainless honing requires exact tool selection and process parameters to avoid work-hardening and ensure long-term corrosion resistance.
What Marine & Chemical Equipment Buyers Value
“In offshore applications, bore pitting leads to immediate seal failure. Using traceable 316L or 2205 duplex honed tubes ensures long-term operational safety in saltwater environments.”
“We need stainless cylinder tubes with verified chemistry and clean, smooth inner bores that meet sanitary and corrosion standards without unexpected dimensional variation.”
“Having complete MTC (EN 10204 3.1) documentation and 100% inspected stainless bores allows us to supply high-end local marine and chemical repair clients with absolute confidence.”

Frequently asked questions
A stainless steel honed tube is a corrosion-resistant cylinder tube manufactured from stainless steel alloys (such as 304, 316L, or 2205) featuring a precision-honed inner diameter for smooth piston movement and high chemical/marine durability.
304 is ideal for standard corrosion resistance in general industrial environments. 316L contains molybdenum for enhanced chloride/saltwater protection, while 2205 Duplex offers superior yield strength and pitting resistance for high-pressure marine and subsea hydraulics.
We standardly achieve inner diameter tolerances of H8 to H9, with internal surface roughness controlled between Ra 0.2 µm and Ra 0.4 µm based on hydraulic cylinder sealing specifications.
All raw materials undergo PMI (Positive Material Identification) spectrometer verification upon arrival. Complete heat-number traceability and EN 10204 3.1 Material Test Certificates are provided with every batch.
Yes, passivation treatment restores the protective chromium oxide layer on the inner and outer surfaces after mechanical processing, maximizing corrosion resistance in aggressive environments.
