Tempering – flame hardening
Tempering – flame hardening
During flame hardening the surface of the product is heated through heavy duty gas jets then water quenched.
The hardened layer is of 1.5-5 mm thickness. This method is usually used for surfaces exposed to wearing.
The advantage is that this technique is cost-effective and quick even by small number of pieces.
In the case of small and precision components the vacuum hardening or plasma nitriding is recommended.
