WebMay 1, 2024 · 1. To obtain a high case hardness it is necessary to reach, during carburizing, a saturation degree in excess of 2% C. Carburizing must be conducted at 950 or 100° C for 15 or 5 hrs. to obtain a total case depth of 1 to 1.2 mm, respectively. 2. The thickness of the layer with over 58 R c depends then on the subsequent heat treatment. WebAug 28, 2014 · The standard carburizing steel 18CrNiMo7-6 is often used when high hardenability is required. Because of its highly fluctuating price, there has always been an incentive to develop Ni-free steel grades. The 23MnCrMo5-5-2 or Jomasco 23mod has been developed for this purpose. ...

WebJun 14, 2006 · Stainless steel components can be cryogenically treated before tempering to transform retained austenite, particularly where dimensional stability is important (e.g. 440C). Temperatures in the range of -100°F (-75°C) to -150°F (-100°C) are common, and ... Carburizing and Nitriding WebJan 31, 2024 · The formation of expanded austenite phase (S-phase) by low-temperature nitriding and carburizing of stainless steels was developed 35 years ago. Initially, this method was applied to austenitic stainless steels, but it has been extended to duplex stainless steels and martensitic precipitation-hardening stainless steels. http://www-eng.lbl.gov/~shuman/NEXT/MATERIALS&COMPONENTS/Pressure_vessels/stainless-steel_heat_treat-article.pdf development of chewing patterns
