Medical stainless steel part:

Stainless Steel as Biomedical Material is an iron-based corrosion-resistant alloy and one of the earliest biomedical alloys developed. It is characterized by easy processing and low price. The corrosion resistance and yield strength can be improved through cold working to avoid fatigue fracture. Stainless steel can be divided into: austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, precipitation hardened stainless steel, etc. according to the microstructure. It is used to make medical devices: knives, scissors, hemostats (Figure 1), needles, It is also used to make artificial joints, fracture fixators, dental orthopedics, artificial heart valves and other devices. Among them, austenitic ultra-low carbon stainless steels 316L and 317L are most widely used in medical applications.
