(3)Semi-Austenitic Hazo Hardening Bakin Karfe, wato, hazo tsaka-tsaki yana taurare bakin karfe, mai dauke da abin da bai gaza 12% chromium ba. Yana da ƙarancin abun ciki na carbon, da aluminum a matsayin babban ɓangaren hazo mai ƙarfi. Irin wannan hazo hardening bakin karfe yana da kyakkyawan aiki gabaɗaya fiye da hazo mai taurin bakin karfe.
(4)Austenitic Hazo Hardening Bakin Karfebakin karfe ne mai tsayayyen tsarin austenite a cikin jihohin da aka kashe da kuma tsufa. Abubuwan da ke cikin nickel da abun ciki na manganese suna da girma, kuma abun ciki na chromium ya fi 13% don tabbatar da juriya mai kyau da kuma juriya na iskar shaka. A lokaci guda, austenitic hazo hardening bakin karfe yawanci ƙara titanium, aluminum, vanadium ko phosphorus a matsayin hazo hardening abubuwa, da kuma ƙara kadan adadin boron, vanadium, nitrogen da sauran abubuwa don samun ingantattun kaddarorin.
Hazo hardening bakin karfe ana amfani da ko'ina a ci-gaba masana'antu. Misali, ana iya amfani da yanayin hazo mai taurin bakin karfe 17-4PH don yin tsarin da ke ƙasa da 370 ° C waɗanda ke buƙatar juriya na lalata, juriya, da ƙarfi mai ƙarfi.
