IN-129/IN-129S is a medical precipitation hardening stainless steel with ultra-high strength and high toughness. Unlike traditional martensitic stainless steel, which achieves high strength by quenching to obtain high carbon martensite, this steel uses Cu, Mo, Ti, Al, Co and other strengthening elements, adopts ultra-low carbon design, and uses second phase aging precipitation to achieve excellent toughness, corrosion resistance, and welding performance while obtaining high strength. At the same time, the material has passed the Vitro (cytotoxicity) test and does not have any potential cytotoxicity, so it can safely come into contact with human tissues, body fluids, or blood, meeting the requirements of all relevant allergy and skin irritation test standards. At present, it is mainly used for surgical medical instruments such as suture needles, surgical blades, biopsy forceps, drills, scissors, files, clamps, punches, and guides.
