6Cr13 is the national standard brand, which belongs to martensitic stainless steel. It is used to make knives, scissors (kitchen knives, scissors) and medical instruments, such as scalpels, hemostatic forceps, etc. The main brands of this type of martensitic stainless steel are 2Cr13, 3Cr13, 6Cr13, 7Cr17, etc. Because knives and scissors have the function of cutting objects, they must be sharp. To be sharp, they must have a certain hardness. This type of stainless steel must be heat treated to undergo internal structural transformation to form tempered martensite. Only after the hardness is increased can it be used for knives and scissors. It is magnetically permeable and can be attracted by magnets.

6Cr13 martensitic stainless steel

The function of knives and scissors to cut items must be sharp. The sharpness must be a certain hardness. Rust-like steel must be heat treated to transform its internal structure to increase the hardness. To make knives and scissors, the internal structure of stainless steel is fire martensite, which is magnetically conductive and attracts magnets
