Gears subjected to high stresses, diverse parts subject to wear and fatigue in service.? In the quenched and tempered condition: safety-critical parts.2. 1.6660 Characteristics? High mechanical properties.? Good fatigue strength.? After carburising, quenching and tempering, the surface hardness is around 730 HV.? Good toughness of the carburised layer.? For some carburising applications, oil quenching can be replaced with gas pressure quenching in order to minimise distortion due to the heat treatment.3.All Grades ComparisonDINEN1.666020NiCrMo13-44.Quality StandardEN 10084 2008 Case hardening steels5. 1.6660 Chemical Composition(%)CMnSiPSCrNiMo0.17-0.220.30-0.600.40 max0.025 max0.035 max0.80-1.203.00-3.500.30-0.506.Hardness requirements for products delivered in the conditionsProcessHardnesstreated to improve shearability277HB maxsoft annealed255HB maxtreated to hardness range207HB-255HBtreated to ferrite-pearlite structure and hardness range197HB-241HB7.Conditions for heat treating test bars and treatment of the steels:ProcessTemperatures (oC)End quench test850Carburizing880-980Core-hardening825-880Case-hardening800-850Tempering150-250 8.Mill′s test certificate:EN 10204/3.1 with all relevant data reg. chem. composition, mech. properties and results of testing.
