GAS Quenching – Understanding , Controlling and Optimizing the Process – I

Performance, safety and environmental considerations can make gas quenching an attractive alternative to conventional oil, polymer and water quenching. But up to now, it has not experienced wide spread implementation due to some issues restricting introduction of this technology. Compared with liquid quenching, the specific advantages of gas quenching include cleaner product surfaces, avoidance of need for washing the parts after quenching, and minimization of environmental problems associated with the handling and disposal of liquid quenching fluids, all these lead to lower the operating costs of a hardening process.
