Ngemva kokucisha nokushisa kwamapayipi angenamthungo, izingxenye ezikhiqizwayo zinezakhiwo ezinhle eziphelele zemishini futhi zisetshenziswa kabanzi ezingxenyeni ezihlukahlukene ezibalulekile zesakhiwo, ikakhulukazi lezo zinduku zokuxhuma, amabhawodi, amagiya namashafu asebenza ngaphansi kwemithwalo eshintshanayo. Kodwa ubulukhuni bobuso buphansi futhi abukwazi ukumelana nokugqoka. I-Tempering + surface quenching ingasetshenziswa ukuthuthukisa ubulukhuni bobuso bezingxenye.

Ukwakheka kwamakhemikhali ayo kuqukethe i-carbon (C) okuqukethwe okungu-0.42~0.50%, okuqukethwe kwe-Si okungu-0.17~0.37%, okuqukethwe kwe-Mn okungu-0.50~0.80%, nokuqukethwe kwe-Cr<=0.25%.
Izinga lokushisa elinconyiwe lokwelashwa: ukwenza kujwayelekile okungu-850°C, ukucisha okungu-840°C, ukushisa okungu-600°C.

Amapayipi ensimbi angenamthungo avamile ngokuvamile enziwa ngensimbi yesakhiwo sekhabhoni ephezulu, engenzima kakhulu futhi kulula ukuyisika. Kuvame ukusetshenziselwa isikhunta ukwenza izifanekiso, amathiphu, okuthunyelwe komhlahlandlela, njll, kodwa ukwelashwa kokushisa kuyadingeka.

1. Ngemuva kokucisha nangaphambi kokuthukuthela, ubulukhuni bensimbi bukhulu kune-HRC55, efanelekile.
Ukuqina okuphezulu kakhulu kokusebenza okusebenzayo yi-HRC55 (i-high frequency quenching HRC58).

2. Ungasebenzisi inqubo yokwelapha ukushisa kwe-carburizing kanye nokucisha insimbi.
Ngemva kokucisha nokushisa, izingxenye zinezakhiwo ezinhle ezibanzi zemishini futhi zisetshenziswa kabanzi ezingxenyeni ezihlukahlukene ezibalulekile zesakhiwo, ikakhulukazi lezo zinduku zokuxhuma, amabhawodi, amagiya namashafu asebenza ngaphansi kwemithwalo eshintshanayo. Kodwa ubulukhuni bobuso buphansi futhi abukwazi ukumelana nokugqoka. I-Tempering + surface quenching ingasetshenziswa ukuthuthukisa ubulukhuni bobuso bezingxenye.

Ukwelashwa kwe-Carburizing ngokuvamile kusetshenziswa ezingxenyeni ezisindayo ezinobuso obungagugi kanye nomongo omelana nomthelela, futhi ukumelana kwayo nokugqokwa kuphakeme kunokucisha kanye nokushisa + ukucisha indawo. Okuqukethwe kwekhabhoni ebusweni kungu-0.8-1.2%, kanti umongo ngokuvamile ungu-0.1-0.25% (0.35% usetshenziswa ezimweni ezikhethekile). Ngemuva kokwelashwa kokushisa, indawo engaphezulu ingathola ubulukhuni obuphezulu kakhulu (HRC58–62), kanti umnyombo unobulukhuni obuphansi kanye nokumelana nomthelela.
