Kuzimitsidwa kwa galasi ndikutenthetsa galasi mpaka kutentha kwa T, pamwamba pa 50 ~ 60 C, ndiyeno mofulumira komanso mofanana kuziziritsa mu sing'anga yozizira (monga quenching sing'anga) (monga mpweya utakhazikika quenching, madzi utakhazikika quenching, etc.) Chosanjikiza ndi pamwamba chimapanga kutentha kwakukulu, ndipo kupsinjika komwe kumabwerako kumakhala kosavuta chifukwa cha kutuluka kwa galasi, kotero kutentha kwa galasi koma palibe kupsinjika maganizo kumapangidwa. Mphamvu yeniyeni ya galasi ndi yotsika kwambiri kuposa mphamvu zongoyerekeza. Malingana ndi makina ophwanyidwa, galasi ikhoza kulimbikitsidwa popanga kusanjikiza kopanikizika pagalasi (yomwe imadziwikanso kuti tempering ya thupi), zomwe zimakhala chifukwa cha makina omwe amagwira ntchito yaikulu.
Pambuyo kuzirala, kutentha kwa kutentha kumachotsedwa pang'onopang'ono, ndipo kupanikizika kosasunthika kumasandulika kukhala kupsinjika kwabwinoko, zomwe zimapangitsa kuti pakhale kugawanika kwapang'onopang'ono pa galasi pamwamba pa galasi. Ukulu wa kupsinjika kwamkati uku kumagwirizana ndi makulidwe a mankhwala, kuzizira kwa kutentha ndi coefficient yowonjezera. Choncho, akukhulupirira kuti pamene galasi woonda ndi galasi ndi otsika kukulitsa coefficient ndi zovuta kuzimitsa zozimitsa galasi mankhwala, structural zinthu zimagwira ntchito yaikulu; , ndi chinthu cha makina chomwe chimagwira ntchito yaikulu. Mpweya ukagwiritsidwa ntchito ngati sing'anga yozimitsira, umatchedwa kuzimitsa kwa mpweya; pamene zamadzimadzi monga girisi, manja silikoni, parafini, utomoni, phula, etc. ntchito monga sing'anga quenching, amatchedwa madzi-utakhazikika quenching. Kuphatikiza apo, mchere monga nitrates, chromates, sulfates, ndi zina zotere zimagwiritsidwa ntchito ngati zozimitsa media. Chitsulo chozimitsira chitsulo ndi ufa wachitsulo, waya wachitsulo wofewa burashi, etc.
