Name Number 16MnCr5 1.7131 870 880~980 860~900 780~820 150~200 ① Time for austenitizing as a guide: 30 to 35 minutes.
② The carburizing temperature will depend on the chemical composition of the steel, the mass of the product, and the carburizing medium. If the steels are direct hardened, in general, a temperature of 950 °C is not exceeded. For special procedures, for example under vacuum, higher temperatures (for example 1020 °C to 1050 °C) are not unusual.
③ When applying the single quench method, the steel is to be quenched from the carburizing temperature or a lower temperature. The lower hardening temperatures are in each case to be preferred, in particular when there is risk of distortion.④ The kind of quenching agent depends on, for example, the shape of the products, the cooling conditions and the amount of furnace filling.
⑤ Time for tempering as a guide: 1 h minimum.
