Abstract

Fremgangsmåte for varmebehandling av tykkveggede smistykker som inkluderer oppvarming av et lavlegert stål til en austenitiseringstemperatur, hvori det lavlegerte stålet omfatter omtrent 0,05-0,2 vekt-% karbon, omtrent 0,3 til 0,8 vekt-% mangan og omtrent 0,25 til 1,0 vekt-% nikkel. Fremgangsmåten inkluderer videre bråkjøling av det lavlegerte stålet i et bråkjølingsmedium, og deretter bråkjøling av det lavlegerte stålet i mindre enn omtrent 30 minutter per tomme av kritisk snitt-tykkelse pluss omtrent 2 timer.
