Description
Стали могут быть использованы и без добавок никел при незначительном снижении их пластичности.Steel can be used without the addition of nickel with a slight decrease in their plasticity.
Оптимальным режимом термообработки вл етс закалка с температуры 1000-1020° в масло с последующим отпуском при 550° li охлаждением на воздухе.The optimal mode of heat treatment is hardening from a temperature of 1000-1020 ° to oil with subsequent tempering at 550 ° li by air cooling.
В результате сопротивление разрыву при 600° составило OKOJD 160 , т. е. почти в 2 раза выще, чем у стали ЗХ2В8- Твердость при комнатной температуре составл ет 56Rc, а после выдержки а)и 500° вAs a result, the tensile strength at 600 ° was OKOJD 160, i.e., almost 2 times higher than that of steel ZX2B8. The hardness at room temperature is 56Rc, and after a) and 500 ° c
течение 256 час снижаетс до 34-43 Re. Но в том и другом случае твердость предлагаемых марок сталей превышает значение этого 11араметра дл известных сталей.the 256 hour period is reduced to 34-43 Re. But in either case, the hardness of the proposed steel grades exceeds the value of this 11 parameter for known steels.
