In the manufacturing of skin stapler metal parts, stainless steel is the most widely adopted material due to its combination of corrosion resistance, biocompatibility, strength, and ease of sterilization. Medical staplers require metal staples that can be safely implanted in human tissue for temporary wound closure and later either naturally expelled or manually removed.
Then, we have a question: What grade of stainless steel material is utilized in the manufacturing of skin stapler metal components? Or, Which medical-grade stainless steel material is used to produce the metal parts of skin staplers?
Types of stainless steel for Skin stapler metal parts
In the production of skin staplers, two types of stainless steel material are widely used.
