I-alloy engu-17-4PH iyinsimbi engagqwali ye-martensitic eqina, eyenziwe ngethusi, i-niobium, ne-tantalum. Izici: Ngemva kokwelashwa kokushisa, umkhiqizo ubonisa izakhiwo ezithuthukisiwe zemishini, ufinyelela amandla okucindezela afinyelela ku-1100-1300 MPa (160-190 ksi). Leli banga alifanele ukusetshenziswa emazingeni okushisa angaphezu kuka-300º C (572º F) noma emazingeni okushisa aphansi kakhulu. Ibonisa ukumelana okuhle kokugqwala ezindaweni ezinomoya kanye ne-acid noma usawoti oncibilikisiwe, okuqhathaniswa no-304, futhi ungcono kunensimbi ye-ferritic engu-430.

Amabanga Okwelashwa Kokushisa kanye Nokuhlukaniswa Kokusebenza: Isici esihlukanisayo se17-4PHKulula kwayo ukulungisa amazinga amandla ngokusebenzisa ukushintshashintsha kwezinqubo zokwelapha ukushisa. Ukuguqulwa kube yi-martensite kanye nokuguga kokuqina kwemvula kuyindlela eyinhloko yokuqinisa. Amazinga avamile okwelapha ukushisa emakethe afaka phakathi i-H1150D, i-H1150, i-H1025, kanye ne-H900.Amanye amakhasimende acacisa isidingo sezinto ezingu-17-4PH ngesikhathi sokuthenga, okudinga ukwelashwa kokushisa. Njengoba amazinga okwelashwa kokushisa ehlukahluka, izimo zokusetshenziswa ezahlukene kanye nezidingo zomthelela kumele zihlukaniswe ngokucophelela. Ukwelashwa kokushisa okungu-17-4PH kuhilela izinyathelo ezimbili: ukwelashwa kwesisombululo kanye nokuguga. Izinga lokushisa lokwelashwa kwesisombululo liyafana ekupholiseni okusheshayo, futhi ukuguga kulungisa izinga lokushisa kanye nenani lemijikelezo yokuguga ngokusekelwe emandleni adingekayo.
Izicelo:
Ngenxa yezakhiwo zayo ezinhle kakhulu zokumelana nokushisa nokugqwala, i-17-4PH isetshenziswa kabanzi ezimbonini ezifana namakhemikhali kaphethroli, amandla enuzi, izindiza, ezempi, ezolwandle, ezimoto, kanye nezindawo zezokwelapha. Esikhathini esizayo, kulindeleke ukuthi ibe nombono wemakethe othembisayo ofana nensimbi ye-duplex.
