Silver Steel Hardening.

  • Heat slowly to 760 - 800°C using the upper end of the temperature range for lower carbon contents and lower end of the temperature range for higher carbon contents.
  • Austenitize until the temperature is uniform. Quench into well-agitated water.
  • The approximate quench hardness is 65 to 69 Rc.

Silver Steel Tempering.

  • Temper immediately after hardening preferably before the tool reaches room temperature.
  • Temper for a minimum of 1 hour at temperatures between 180 - 350°C, dependent upon the final hardness required.
