Heat Treatment Processes Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
Wetting of the base materials by the filler metals is enabled by the use of a suitable flux or by acoustic vibrations. The difference between soldering and brazing lies in the temperature of the heating process: soldering occurs at temperatures less than 450Â°C, and brazing occurs at temperatures over 450Â°C.
