Problems solved by technology

Commonly used blades are made of stainless steel. There are many types of stainless steel. According to the structure of steel, there are austenite, martensite, ferrite, and duplex. There are many subdivided brands for these four categories, such as commonly used Austenitic stainless steel includes 304, 309, 310, 316, 304L, 316L, etc., which can be used to make knife handles. Commonly used materials for scalpels include a few high-strength stainless steels such as 6Cr13 and 440C, but the sharpness of stainless steel blades is slightly worse. , the surgical wound is relatively large, resulting in slow healing
