The endothermic gas carburizing method, where air and methane, propane or butane gas are mixed and generated, has been operated for over 40 years at least. The mechanism of the endothermic gas carburizing method has already been solved and is known. The other method, the direct carburizing method by flowing hydrocarbon gas into a carburizing furnace directly without using the gas generator, has been recently adopted and popular from the point of saving energy.
