Sep 03,2014·The carburizing process is characterized by the following key points.It is applied to low carbon steels.Low carbon steel is in contact with a high-carbon gas,liquid or solid.It produces a hard steel surface by increasing the carbon content of the surface.The increase in surface hardness results in enhanced wear and fatigue resistance.Case hardening steel - IMOAHigh-performance NiCrMo case-carburizing steels provide deep hardening ability and possess high fatigue resistance.Currently,the grade 18CrNiMo7-6 is the standard gear steel for windmill gearboxes.With respect to further optimizing carburizing steels for large and heavily loaded gears,the following priorities can be defined:Cited by 18Publish Year 2000Author Dennis W.HetznerLOW-PRESSURE CARBURIZING PROCESS DEVELOPMENTand produce the required carburized surface.These baseline cycles were completed using standard carburizing steels (AISI 1018 and AISI 9310).Car - burizing parameters for these initial cycles were selected using values common to industry practices for these grades of steel.While the required carburizing re-sults were achieved in the furnace,
