Munkhaniyi mwatsatanetsatane,SAKYSTEELakufotokoza zakusiyana kwakukulu pakati pa chitsulo chosapanga dzimbiri cha 15-7PH ndi 17-4PH, kuthandiza mainjiniya, opanga zinthu, ndi oyang'anira kugula kusankha zinthu zoyenera kwambiri pazosowa zawo.
1. Chiyambi cha Zitsulo Zosapanga Dzimbiri Zouma ndi Kuuma kwa Mvula
Zitsulo zosapanga dzimbiri zouma ndi kuuma kwa mvula (PH) zimapeza mphamvu zawo kudzera mu njira ziwiri:
-
Chithandizo cha yankho (kunyowetsa)kupanga kapangidwe kofanana.
-
Kukalamba (kuuma kwa mvula)kupanga tinthu tating'onoting'ono tomwe timaletsa kuyenda kwa zinthu zomwe zimasokoneza malo, zomwe zimawonjezera mphamvu ndi kuuma.
Njirayi imalola zitsulo zosapanga dzimbiri za PH kukwaniritsamphamvu yamakina yokwera kwambirikuposa magiredi wamba a austenitic (monga 304 kapena 316), pamene akusungakukana dzimbiri bwinondikusinthasintha kwa kupanga.

Njira yothira madzi yochokera ku aluminiyamu iyi imaperekamphamvu ndi kuuma kwakukulu kwambirindi kukana dzimbiri bwino.
3.2 17-4PH: Aloyi wa Martensitic Wolimba ndi Mkuwa
17-4PH imalimbikitsidwa ndimitsinje yabwino kwambiri yokhala ndi mkuwaZopangidwa panthawi ya ukalamba. Chitsulocho chimatsalabemartensiticpambuyo pa chithandizo cha mankhwala ndi ukalamba, ndipo imadziwika chifukwa chakusinthasintha kwabwino kwambiri komanso kosavuta kukonza.
Ngakhale kuti imapereka mphamvu zochepa kuposa 15-7PH, imaperekakukana bwino dzimbirindikulimba kwapamwamba.
4. Kuyerekeza kwa Katundu wa Makina
| Katundu | 15-7PH | 17-4PH |

-
Kusintha kukhala Martensite (Mkhalidwe TH1050):Ntchito yozizira kenako n’kutenthetsa pa 565°C kwa ola limodzi.
-
Kukalamba (Mkhalidwe RH950):510°C kwa maola 4, mpweya uzizire.
Njira yochiritsira imeneyi imapanga kapangidwe ka martensitic kamphamvu kwambiri.
6.2 17-4PH
-
Chithandizo cha Mayankho:1040°C kwa mphindi 30–60, mpweya uzizire.

9. Kuyerekeza kwa Mapulogalamu
15-7PH Zogwiritsira Ntchito Zitsulo Zosapanga Dzira
-
Zigawo zamlengalenga(masika, mabelu, ma diaphragm)
-
Mitsempha yamagazi yothamanga kwambirindi ma valve
