Aloyi ya 17-4PH ndi chitsulo chosapanga dzimbiri cholimba chomwe chimapangidwa ndi mkuwa, niobium, ndi tantalum. Makhalidwe: Pambuyo potenthetsera, mankhwalawa amakhala ndi mphamvu zabwino zamakina, zomwe zimapangitsa kuti mphamvu yake ikhale yolimba mpaka 1100-1300 MPa (160-190 ksi). Mtundu uwu suyenera kugwiritsidwa ntchito kutentha kopitilira 300º C (572º F) kapena kutentha kotsika kwambiri. Umasonyeza kukana dzimbiri bwino m'malo okhala ndi asidi kapena mchere wochepa, wofanana ndi 304, komanso wapamwamba kuposa chitsulo cha ferritic 430.

Magiredi Othandizira Kutentha ndi Kusiyanitsa kwa Magwiridwe Antchito: Mbali Yodziwika ya17-4PHNdi kosavuta kusintha mphamvu zake kudzera mu kusintha kwa njira zochizira kutentha. Kusintha kukhala martensite ndi kukalamba kwa mvula ndiyo njira yayikulu yolimbikitsira. Mitundu yodziwika bwino yochizira kutentha pamsika ndi H1150D, H1150, H1025, ndi H900.Makasitomala ena amanena kuti kufunikira kwa zinthu za 17-4PH panthawi yogula, zomwe zimafuna chithandizo cha kutentha. Popeza mitundu yosiyanasiyana ya chithandizo cha kutentha imasiyanasiyana, mikhalidwe yosiyanasiyana yogwiritsira ntchito ndi zofunikira pakukhudzidwa ziyenera kudziwika bwino. Chithandizo cha kutentha cha 17-4PH chimaphatikizapo magawo awiri: chithandizo cha yankho ndi ukalamba. Kutentha kwa chithandizo cha yankho ndi kofanana kuti kuziziritse mwachangu, ndipo ukalamba umasintha kutentha ndi kuchuluka kwa nthawi yokalamba kutengera mphamvu yofunikira.
Mapulogalamu:
Chifukwa cha mphamvu zake zabwino kwambiri zopewera dzimbiri ndi makina, 17-4PH imagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta, mphamvu ya nyukiliya, ndege, asilikali, zapamadzi, zamagalimoto, ndi zamankhwala. M'tsogolomu, ikuyembekezeka kukhala ndi chiyembekezo chabwino pamsika chofanana ndi chitsulo cha duplex.
