Let’s get into what makes our 17-4PH stainless steel tube for medical devices so special. This precipitation-hardening alloy is a powerhouse, packing 15-17.5% chromium for top-notch corrosion resistance, 3-5% nickel for toughness, and 3-5% copper plus 0.15-0.45% niobium for that extra strength boost. With carbon kept below 0.07%, it’s compliant with ASTM A564, offering a unique combo of high strength and corrosion resistance. We produce these tubes in diameters from 0.8mm to 10mm, with wall thicknesses down to 0.1mm, perfect for applications like laparoscopic tools or dental handpieces. Heat treatment allows us to dial in hardness levels, hitting tensile strengths up to 1380 MPa, so these tubes can take a beating without buckling.

Our manufacturing process is dialed in for precision. We cold-draw tubes to tolerances of ±0.01mm, ensuring they fit seamlessly into complex devices like biopsy needles or retractors. Electropolishing gives them a silky-smooth Ra <0.3µm finish, cutting down on bacterial adhesion and making sterilization a snap. Unlike softer alloys, 17-4PH’s high yield strength—up to 1170 MPa—means our tubes hold up under torque and flexing, critical for tools in robotic surgeries. We also run rigorous fatigue tests, mimicking thousands of use cycles, to ensure they last through years of heavy-duty procedures. While slightly magnetic, they’re still safe for most imaging setups, adding versatility.
