304 Cold Rolled Stainless Steel Strip For Hypodermic Needle

Product Features
• Processing and Forming: Using 304 stainless steel strip as the raw material, needle tube blanks are produced through precision rolling (thickness can be controlled within 0.1-1mm), slitting, and stretching. Finished products such as medical needle tubes and industrial probes are then polished, cut, and ground. The strip material boasts a high surface finish (typically Ra ≤ 0.8μm) and high dimensional accuracy (thickness tolerance ±0.01mm), ensuring smooth inner walls and uniform outer diameters after forming the needle tube.
• Performance Adaptability: Its excellent ductility enables it to be stretched into extremely fine needle tubes (such as medical needles with diameters under 0.2mm) without cracking. Its corrosion resistance ensures that the needle tubes will not rust or contaminate the medium when in contact with liquid medicine, blood, or industrial fluids.

Applications
• Medical Devices: It is the core material for medical injection needles, infusion needles, and puncture needles, and must meet biocompatibility and sterility requirements to avoid irritation or allergies to human tissue.
• Laboratory Equipment: It is used in sampling needles and analytical instrument probes, requiring resistance to chemical reagents (such as acidic and alkaline solutions and organic solvents).
• Precision Industries: Applications such as microprobes (for testing circuit boards) in the electronics industry and inkjet printer nozzles rely on its high precision and wear resistance.

Advantages:
◦ High Safety: Meets medical and food-grade standards, is non-toxic, and suitable for contact with the human body or sensitive media.
◦ Excellent Processability: Can be stretched into thin-walled, narrow-diameter needles to meet precise dimensional requirements.
◦ High Corrosion Resistance: Can withstand a variety of chemical environments, extending the life of the needle.
