15-7M0Ph zitsulo aloyi akhoza kupirira mitundu yonse yozizira kupanga ndi kuwotcherera ndondomeko pansi chikhalidwe cha austenite.Ndiye kudzera kutentha mankhwala angapeze
mphamvu yapamwamba;Pansi pa 550 ℃ yokhala ndi mphamvu yotentha kwambiri, idapangidwa kuti ikhale yolimba kwambiri kuposa 17-4 PH.Aloyiyo ndi martensitic mu kapangidwe ka annealed ndipo imalimbikitsidwanso ndi kutentha kwapang'onopang'ono kutentha komwe kumapangitsa kuti pakhale mkuwa wokhala ndi gawo mu alloy.

•Ingathe kupirira mitundu yonse yozizira kupanga ndi kuwotcherera ndondomeko pansi pa chikhalidwe cha austenite.ndiye kudzera kutentha mankhwala angapeze apamwamba kwambiri
mphamvu, Pansi pa 550 ℃ ndi mphamvu yabwino kwambiri kutentha.
•Katundu wowotcherera magetsi: Chitsulocho chimatha kutengera kuwotcherera kwa arc, kuwotcherera kukana ndi kuwotcherera kwa arc otetezedwa ndi gasi, kuwotcherera kotetezedwa ndi gasi ndiye kwabwino kwambiri.
Kuwotcherera nthawi zambiri kumachitika muzinthu zolimba zochizira, ndipo siziyenera kutenthedwa musanawotchere.
Pamene kuwotcherera kumafuna mphamvu zambiri, 17-7 yokhala ndi m'munsi mwa δ- ferrite imasankhidwa makamaka, waya wowotcherera wa austenitic wosapanga dzimbiri angagwiritsidwe ntchito.
Amagwiritsidwa ntchito kupanga zida zopangira ndege zowonda-khoma, zotengera zamitundu yonse, mapaipi, masika, filimu ya valve, shaft ya ngalawa,
kompresa mbale, zigawo riyakitala, komanso zosiyanasiyana kapangidwe zigawo zikuluzikulu za zida mankhwala, etc.
