Abstract

Предложен способ термообработки толстостенных поковок, включающий в себя нагрев низколегированной стали до температуры аустенизации, при этом низколегированная сталь содержит углерод в количестве приблизительно 0,05-0,2 мас.%, марганец в количестве приблизительно 0,3-0,8 мас.% и никель в количестве приблизительно 0,25-1,0 мас.%. Способ дополнительно включает в себя закалку низколегированной стали в закалочной среде и последующий отпуск низколегированной стали в течение менее приблизительно тридцати минут на дюйм толщины критического сечения плюс приблизительно 2 ч.
