Flame Hardening
PROCESS DESCRIPTION
Flame hardening is the name given to short-term, localised heating and cooling of a component made of temperable steel. During heating, the austenitising temperature, and when cooling the so-called “critical cooling speed�?, must not be exceeded. Hardening/tempering changes the steel´s structure. Using an excessive fuel gas flame can achieve an additional carburisation of the surface.
MESSER SOLUTION
Fuel gas and oxygen are used to create the flame. Messer supplies gases and know-how for your requirements.
Advantages:
- Greater wear resistance
