X65Cr13 & X68Cr13 are martensitic stainless steel with high carbon content. It can reach high hardness while maintaining corrosion resistance. X65Cr13 & X68Cr13 are typically used for blades (knifes, Scalpels, Razor blade, Machine Knives). We have introduced razor blade application in our blog. Depending on the heat treatment method, the hardness can reach beyond 790HV or 64HRC.
Below table demonstrates comparison of chemical compositions among similar steel grades of X65Cr13 & X68Cr13.

For the sharpness of the blades, hardness after heat treatment (quenching and tempering) is essential. For the hardness, how small and evenly distributed the carbon is important. If carbon particle (carbide) is big, “large tipping (loosing a big tip of the blade)” may happen and heat treatment must be more slowly. If carbide is not evenly distributed, the hardness may be uneven and some deforms during heat treatment may happen. The removal of impurities is also important for stable hardness after heat treatment.
