Materials Used for Orthopedic Instruments

STAINLESS STEEL Most instruments are fabricated from stainless steel which contains a minimum of 12% chromium for satisfactory corrosion resistance. The selection of a stainless steel is based on several factors, such as design and function. Stainless steel used for orthopedic implants or instruments are classified according to composition and microstructure. The most versatile compositions are the straight chromium alloys with a martensitic microstructure and the chromium-nickel alloys with an austenitic microstructure. Other types of stainless steel known as ferritic…
