SUS304 Medical Grade Stainless Steel Injection Needle Tube , Lancet Bevel Point , 24G 0.55MM

Medical Injection Needle Tubes are generally manufactured by SUS304, SUS316L medical grade stainless steel grades due to the great corrosion resistance of these raw materials. The needle point is mainly lancet bevel point, which has a regular bevel of 12-14 degree. There are four main types of medical injection needle tubes: Intravenous, Intramuscular, Subcutaneous, and Intradermal Injection Needle Tubes. All of our Injection needle tubes are produced according to ISO9626 international standard. To meet clients' different requirements of sizes, length and needle point shapes, we can customize specific needle tubes for clients according to the drawings. Our company has more than 10 production lines for making needle tubes and we have advanced machines for grinding. Our quality assurance system is certified by EN ISO13485 standard.

Key Features:

• Corrosion Resistance: SUS316 excels in saline/chloride environments; SUS304 suitable for general use.
• Biocompatibility: Compliant with ISO 10993, ensuring safety for human tissue contact.
• Precision Manufacturing: Tight tolerances (±0.01 mm) for consistent performance.
• Surface Finish: Electropolished or mechanically polished to reduce friction and tissue damage.
• Mechanical Properties: High tensile strength (SUS304: ~520 MPa, SUS316: ~580 MPa) for durability.

Material Grades:

• SUS304: Austenitic stainless steel with 18% chromium and 8% nickel. Offers good corrosion resistance and formability. Commonly used in non-implantable medical devices.
• SUS316/316L: Contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, enhancing resistance to chlorides and acids. The low-carbon 316L variant is preferred for implants and harsh environments. Both grades are non-magnetic and biocompatible.

Injection Needle Tubes are selected according to length in mm (depth of injection) and diameter in gauge or mm (viscosity). For example, the selection of Intramuscular and Subcutaneous Injection Needles is as follows:

Applications:

• Medical: Hypodermic needles (subcutaneous, intramuscular), catheters, biopsy needles, insulin pens, IV cannulas, surgical instruments.
• Non-Medical: Laboratory equipment, veterinary devices, micro-needles for transdermal drug delivery.
• Specialized Uses: Implantable devices (316L only), chemotherapy, and contrast agent delivery.
