1, Kuchepetsa kupsinjika
Kuchepetsa kupsinjika, komwe kumadziwikanso kuti kutsika kwa kutentha (kapena kutenthetsa), komwe kumagwiritsidwa ntchito kwambiri kuthetsa kuponyedwa kwa annealing, forging, kuwotcherera, kugudubuzika, zidutswa zotsalira zotsalira ndi zina zotero. Ngati si kuthetsa mavuto amenewa adzachititsa chitsulo patapita nthawi, kapena mapindikidwe kapena ming'alu mu wotsatira Machining ndondomeko.

2, Kuthamanga kwa mpira
Mpira annealing makamaka ntchito HYPEREUTETOID mpweya zitsulo ndi aloyi chida zitsulo (monga kupanga zida kudula, zida kuyeza, zisamere nkhungu ntchito zitsulo). Cholinga chake chachikulu ndi kuchepetsa kuuma kwa machinability, ndi kuumitsa kukonzekera m'tsogolo.

3, Kuwotcha kwathunthu ndi kutenthetsa kwapakati
Imadziwikanso kuti annealing recrystallization annealing, yomwe nthawi zambiri imatchedwa annealing, annealing imagwiritsidwa ntchito kwambiri popanga sub-eutectoid yamitundu yosiyanasiyana ya carbon ndi alloy steel cast, forging and hot-rolling profiles, nthawi zina pakupanga welded. Kawirikawiri monga ena a kulemera kwa workpiece si komaliza kutentha mankhwala, kapena monga chisanadze kutentha mankhwala ena mwa workpiece.
