Disposable SUS304 Stainless Steel Hypodermic Tubing For Medical Syringe Needle ISO9626

ISO9626 SUS304 Disposable Stainless Steel Hypodermic Tubing refers to precision-engineered, thin-walled capillary tubes manufactured from medical-grade SUS304 (equivalent to AISI 304) stainless steel. These tubes are specifically designed for the production of single-use hypodermic needles, biopsy needles, and other minimally invasive medical devices. The tubing strictly conforms to ISO 9626:2016 – the international standard that specifies dimensions, mechanical properties, and surface finish requirements for stainless steel needle tubing for medical devices. YUHONG GROUP provides 10G-34G medical grade stainless steel hypodermic tubes. Non-standard sizes can also be customized. Our medical capillary tubes are widely used for hypodermic needles, syringe needles, IV cannulas/catheters, infusion needles, blood collection needles, beauty needles, dental needles, and so on.

SUS304 is the most widely used austenitic stainless steel in medical device manufacturing. For hypodermic tubing, it is selected due to its exceptional balance of strength, ductility, and biocompatibility. Unlike standard industrial 304 tubing, medical-grade hypodermic tubing undergoes stricter quality controls, including:

• Good Cleanliness: Free from residual oils, cutting fluids, or particulates.
• Burr-free ends: Critical for patient comfort and tissue penetration.
• Straightness: Tight tolerance on deviation to ensure needle straightness.
• Passivation: Surface treated to maximize corrosion resistance and remove free iron.

Key Features of Medical Grade Stainless Steel 304 Hypodermic Tubes:

• High Corrosion Resistance: Withstands autoclaving, saline exposure, and bodily fluids without pitting.
• Excellent Ductility: Can be bent into lancets or biopsy needles without fracturing.
• High Tensile Strength: Resists buckling during skin penetration.
• Non-Toxic & Biocompatible
• Tight Dimensional Accuracy
• Burr-Free Sharpening Ready: The tubing can accept a triple-bevel or lancet-point grind for needle tips.

Different Applications of SUS304 Medical Capillary Tubes:

• Syringe Needles (Primary Use): Disposable hypodermic needles for vaccine delivery, blood sampling, and medication injection.
• Biopsy Needles: Core needle biopsy devices for tissue sampling.
• Catheter Introducers & Guidewires
• Dental Needles: Ultra-fine 30G–32G.
• Lancets & Lancing Devices: Short, rigid tubes for capillary blood glucose testing.
• Ophthalmic Instrument
• Endoscopic Accessories: Injection needles for sclerotherapy or polypectomy.
• Laboratory & Microfluidics: Precision fluid dispensing tips, micro-syringe needles, and chromatography columns.
• Veterinary Needles: 14G–18G.
• Industrial / Non-Medical Use: Micro-dispensing nozzles, welding tips, and precision fluid transfer in semiconductor or inkjet printing.
