316L Cold Rolled Stainless Steel Strip For Medical

Balanced mechanical properties:

It has sufficient strength (tensile strength ≥480MPa) to ensure that the needle tube is not easy to bend and break during puncture, and has a certain toughness to avoid brittle cracking. It is suitable for making thin-diameter (such as less than 0.2mm) microinjection needles.

Typical application scenarios
• Medical needles: such as intravenous needles, vaccination needles, insulin pen needles, puncture needles (biopsy needles, infusion port needles), etc., which are in direct contact with human tissues and body fluids and rely on their corrosion resistance and biocompatibility (in compliance with ISO 10993 biosafety standards).
• Precision industrial needles: precision dispensing needles (delivering glue, ink), laboratory micro-sampling needles, optical fiber cable threading needles, etc. used in the electronics industry, which need to be resistant to chemical reagents and have precise dimensions.
• Medical equipment components: as connecting needles for infusion pumps and syringe pumps, or micro-catheters in hemodialysis equipment, they can withstand long-term contact with liquid medicine and blood.

In summary, the core value of 316L stainless steel needle tube material lies in its super corrosion resistance, precision processing and biosafety. It is an ideal material for high-demand needle tubes (especially medical ones), and its performance directly determines the reliability and user experience of the needle tube.
