At our company, we’re all about crafting passivated 420 stainless steel tube for surgical tool fabrication that empowers surgeons to perform with precision and confidence. These tubes aren’t just metal—they’re the backbone of tools like scalpels, forceps, and endoscopes that make life-saving procedures possible. With a focus on hardness, durability, and affordability, we’re delivering solutions that keep operating rooms running smoothly and patients healing faster.
Let’s dive into what makes our 420 stainless steel tube for surgical tool fabrication a standout. This martensitic alloy is a tough contender, packing 12-14% chromium for solid corrosion resistance and 0.15-0.40% carbon for high hardness after heat treatment. Compliant with ASTM A276, it’s perfect for medical-grade applications. We produce these tubes in diameters from 1mm to 10mm, with wall thicknesses as low as 0.1mm, ideal for slender endoscopic shafts or robust scalpel handles. Our passivation process enhances corrosion resistance, creating a protective oxide layer that stands up to harsh sterilization cycles, while heat treatment achieves hardness up to 50 HRC for razor-sharp edges.

We’re obsessive about precision. Our tubes are cold-drawn to tolerances of ±0.01mm, ensuring they fit perfectly into complex surgical tools like biopsy forceps. The passivated Ra <0.4µm finish resists corrosion from blood and saline, making cleaning and sterilization a breeze. We test for wear resistance, simulating thousands of cutting cycles to confirm tools stay sharp and durable. Magnetic properties are no issue for most surgical applications, but we optimize surface treatments to minimize interference in imaging-heavy procedures. We also offer custom laser-cutting and sharpening, tailoring tubes to specific tool designs for optimal performance.
