Grain Size Fine grain steel shall have an austenite grain size of 5 or finer. Sampling and sample preparation shall be as specified in ISO 643. The grain size shall be determined from a carburized specimen. Carburization shall be achieved by maintaining the specimen in carburizing powder at 950°C ± 10°C for 6 h. This is generally done by keeping the carburizing chamber at 950°C ± 10°C for 8 h, including a preheating period. In most cases, a carburized layer of approximately 1 mm is obtained.; Grain size of 5 or finer in accordance with ISO 653.; Steel shall have an austenite grain size of 5 or finer in accordance with ISO 643. view details

Heat Treatments

  • Core-hardening at 830 - 870°C, case hardening at 780 - 820°C, quenching. Tempering at 150 - 200°C.
  • End quench test: Quench from 860°C Carburizing: 880 to 980°C; NOTE: If steels are direct hardened, in general, a carburizing temperature of 950°C is not exceeded. For special procedures, for example under vacuum, higher temperatures (for example 1020 to 1050°C) are not unusual. Core hardening: 830 to 870°C; Case hardening: 780 to 820°C; Tempering: 150 to 200v (as a guide, for 1 hour minimum).
