Our 17-4PH stainless steel tube is a game-changer for high-precision medical equipment, delivering the strength and reliability that surgeons and manufacturers demand. This isn’t just any tubing—it’s a precipitation-hardening alloy crafted for top-tier performance in critical applications. With its stellar corrosion resistance and mechanical strength, our 17-4PH tube is perfect for surgical instruments, endoscope shafts, and catheter tubing that need to perform flawlessly in the operating room. We’ve optimized our production to meet ASTM F899 standards, ensuring every tube supports devices that save lives.
What makes our 17-4PH stainless steel tube stand out is its robust composition. Packed with 15-17.5% chromium, 3-5% nickel, and 3-5% copper, with carbon below 0.07%, it’s engineered for high strength and durability. Heat treatment pushes its tensile strength to 930-1100 MPa and hardness to 30-44 HRC, making it ideal for equipment that faces heavy stress. Its yield strength of 725-860 MPa ensures it holds up under repetitive use. We extrude and polish each tube with precision, achieving wall thicknesses as low as 0.1mm and diameters from 1mm to 10mm, perfect for intricate medical designs.

Corrosion resistance and biocompatibility are non-negotiable for medical equipment, and our 17-4PH tube delivers. The high chromium and copper content forms a strong passive oxide layer that resists pitting from sterilization chemicals and body fluids. While it’s not suited for permanent implants due to slightly higher ion release than 316LVM, it’s ideal for temporary-use devices, with studies showing minimal tissue reactivity. Our electropolishing process creates a mirror-smooth surface, reducing bacterial adhesion by up to 25%, per clinical data, which lowers infection risks in surgical settings.
