Forming gas treatment of metals, because it reduces oxides on the metal surface. Forming gas Forming gas is a mixture of hydrogen (mole fraction varies) and nitrogen. It is sometimes called a "dissociated ammonia atmosphere" due to the reaction which generates it: It can also be manufactured by thermal cracking of ammonia, in an ammonia cracker or forming gas generator. Forming gas is used as an atmosphere for processes that need the properties of hydrogen gas. Typical forming gas formulations (5% H2 in N2) are not explosive. It is used in chambers for gas hypersensitization, a process in which photographic film is
Endothermic gas gas in the endothermic atmosphere is combined with an additive gas including natural gas, propane (CH) or air and is then used to improve the surface chemistry work positioned in the furnace. There are two common purposes of the atmospheres in the heat treating industry: Principal Components of Endothermic Gas Generators : Chemistry of Endothermic Gas Generators: Applications of Endothermic Gas Generators: It is relatively simple to operate and maintain endothermic gas generators, however, maintenance such as the burnout process is often overlooked. Troubleshooting the Endothermic Gas Generator (Cracking at 1040°C): Endothermic gas Endothermic gas is a gas that inhibits
