Technological properties

Name The value
Features of production Bars and stripes on the other 14-1-2394-78 are supplied in the annealed condition with hardness not more than 285 HB (indentation diameter - not less than 3.6 mm). To check the hardness after quenching and tempering, the samples are subjected to hardening with 1240-1260 °C. the samples were Then subjected to two or three times the release at a temperature of 560-580 °C with exposure for 1 hour (for every time).
Features of heat treatment To determine the depth bezoperatsionnogo layer M2 according to the method GOST 1763 samples subjected to heat treatment in the following mode: Annealing with 1240-1260 °C water (the temperature of the 1st bath 190-220 °C, 10 minutes exposure) + Vacation (temperature 2nd bath 580-600 °C, exposure time 10 minutes).
Redness The red hardness of steel should provide a hardness of at least HRC 58 after a four-hour tempering at the temperature of 640 °C.
