Common Applications:

  • Cutlery (e.g., knife blades)

  • Valve components

  • Pump parts

  • Fasteners

  • Steam and gas turbine parts

  • Kitchen utensils

  • Dental and surgical instruments

Heat Treatment Process:

 

  • Annealing: 815–900°C, followed by slow furnace cooling

  • Hardening: 925–1010°C, followed by oil or air quenching

  • Tempering: 150–370°C, depending on required hardness/toughness balance

Limitations:

 

  • Less corrosion-resistant than austenitic stainless steels (like 304 or 316)

  • Can become brittle if not properly tempered after hardening

  • Prone to scaling and oxidation at high temperatures
