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 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.
