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.

DIN 1652-3: 1990 / Bright steel made from case hardening steel; technical delivery conditions
Heat Treatments
- Carburizing at 880 - 980°C. Core-hardening at 860 - 900°C, case hardening at 780 - 820°C, quenching. Tempering at 150 - 200°C.
- End quench test: Quench from 900°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: 860 to 900°C; Case hardening: 780 to 820°C; Tempering: 150 to 200°C (as a guide, for 1 hour minimum).
