At our company, we’re all about crafting medical-grade 304 stainless steel tube for hypodermic needles that make medical procedures smoother, safer, and more reliable. These tubes aren’t just metal—they’re the core of needles that deliver life-saving drugs, collect critical samples, and support minimally invasive diagnostics. With a focus on affordability and performance, we’re helping healthcare providers get the job done without breaking the bank.
Let’s dive into what makes our 304 stainless steel tube for hypodermic needles a standout. This alloy is a reliable workhorse, packing 18-20% chromium for solid corrosion resistance against bodily fluids and sterilization processes, plus 8-10.5% nickel for toughness. With carbon kept below 0.08%, it’s compliant with ASTM A240, offering great formability for precision needle designs. We produce these tubes in diameters from 0.2mm to 3mm, with wall thicknesses as low as 0.05mm, perfect for fine-gauge needles used in insulin delivery or biopsies. The material’s tensile strength of 515-690 MPa and elongation over 40% ensure needles can pierce tissue without bending or breaking.

We’re obsessive about precision. Our tubes are cold-drawn to tolerances of ±0.005mm, ensuring they fit seamlessly into needle assemblies for consistent performance. A polished Ra <0.3µm finish resists corrosion from saline or blood and makes sterilization a snap. We test for fatigue resistance, simulating thousands of insertions to confirm durability in high-use settings like vaccination clinics. Non-magnetic properties keep our tubes imaging-friendly, a plus for procedures involving fluoroscopy. We also offer custom beveling and laser-welding, tailoring tubes to specific needle designs for optimal sharpness and strength.
The hypodermic needles market is thriving, valued at USD 2.3 billion in 2025 and projected to hit USD 3.7 billion by 2032 at a 5.4% CAGR. Rising chronic diseases—think diabetes affecting over 500 million people globally—are driving demand for insulin and other injectable therapies. Vaccination programs are expanding, with over 5 billion doses administered annually, and diagnostic procedures like biopsies are on the rise. Our medical-grade 304 stainless steel tube for hypodermic needles is built for this, offering the strength for reliable piercing and the affordability to support mass production.
