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.
These processes involve heating of materials to a specific temperature, where the filling material becomes a liquid while joining metals remain as solids. The key difference between these two methods is the heating temperature; brazing uses a higher temperature above 450Â°C, and soldering uses a temperature below 450Â°C. What is Soldering? Soldering is used to join two or more metal materials together using filler solder material.
