    Name The value
    Macrostructure and pollution The macrostructure of the steel on the other 14-1-1893-76 on cross etched templeto cut from billets and forgings should not have shrinkage, porosity, bubbles, cracks and inclusions that are visible without using the magnifying devices.
    Corrosion resistance Arbitration test steel to intergranular corrosion produced in plavochek control according to GOST 6032 method AMU, if the duration of boiling of the samples for 24 hours, after heat treatment of the samples in regime: Quenching in water from 1030-1050 °C (aging 1 HR) + provoking Subsequent heating to 650 °C (aging for 1 h), air cooling.
