Depending on the geometry and the steel-grade of the quenched component, either helium or nitrogen is used.See all results for this question
High pressure gas quenching is an environmentally friendly and low distortion quench process compared to liquid quenching such as oil, polymer or water. The dry gas quenching has the following advantages compared to liquid quenching:See all results for this questionSingle-Piece, High-Volume, and Low-Distortion Case high pressure gas quenchingdistortion analysis in gearsAfter the appropriate shape is obtained using a variety of CNC machines, each gear is case hardened to impart the right mechanical properties: hard, wear-resistant teeth and a ductile, impact- and load-bearing core. In most cases, the heat treatment used is carburizing, quenching, and tempering , . The most common steels for carburizing are the EN 16MnCr5 or 20MnCr5 grades (AISI/SAE 5115, 5120, 8620), their equivalents, oSee more on thermalprocessing high pressure gas quenchingdistortion analysis in gearsReducing Distortion in Heat-Treated Gears | Gear Solutions high pressure gas quenchingdistortion analysis in gearsOf these factors, those resulting from transformation during heating and cooling (Figure 2) produce internal stress/strain induced by volumetric changes due to these transformations and result in localized deformation and general part distortion. Part design/geometry, steel production methods, and steel quality are important as well. The shape of the part, or the design geometry, dictates to a large extent the post heat treat distortion results. Most often this parameter is fixed for a given application.

Jul 01, 2007 · While better than some mediums such as water or brine, other mediums such as salt or high pressure gas quenching tend to produce less overall distortion. A key consideration, however, is the uniformity/repeatability of the distortion profile, and oil quenching has the ability to produce a very consistent profile.LOW-PRESSURE CARBURIZING HIGH-PRESSURE GAS pressure carburizing plus high-pres-sure gas quenching has become the standard process for diesel fuel injec-tors and premium transmission gears in Europe. This influenced North American manufacturers such as Caterpillar Inc., which in 1999 led the way and started to vacuum carburize and 20-bar gas quench their diesel fuel injector components.Some results are removed in response to a notice of local law requirement.

In order to increase the load carrying capacity of hardened gears, the distortion of gear teeth caused by quenching must be removed by precision cutting (skiving) and/or grinding. In the case of large gears with large modules, skiving by a carbide hob is more economical than grinding when the highest accuracy is not required.See all results for this questionHow does HPGQ help in the hardening of steel?By enhancing gas pressure and gas velocity as well as through the development of separate quench chambers, or so called cold chambers, HPGQ has become established also for the hardening of low alloyed casehardening steels and quenched and tempered steels.See all results for this questionHigh pressure gas quenching: Distortion analysis in gears high pressure gas quenchingdistortion analysis in gearsDec 15, 2012 · The analysis of distortions, hardness level and microstructure of the surface layers of the toothed gears after low pressure carburizing and high pressure gas quenching is presented in this paper.
