Cutlery: Kitchen knives, scissors, and other cutlery tools due to its ability to achieve a sharp edge and maintain reasonable corrosion resistance.
Razor Blades: Often used in the manufacture of razor blades thanks to its hardness after heat treatment.
Surgical and Beauty Instruments: Scalpels, tweezers, and beauty tools that benefit from its hardness and corrosion resistance in atmospheric conditions.
Automotive Parts: Certain mechanical parts where wear resistance is necessary.
Mechanical Components: Used in springs and other components that require strength and toughness.
