I-17-4PH ingxubevange iwukuqina kwezulu, insimbi engagqwali ye-martensitic eyenziwe ngethusi, i-niobium, ne-tantalum.Izici: Ngemva kokwelashwa kokushisa, umkhiqizo ubonisa izakhiwo ezithuthukisiwe zemishini, ukufeza amandla okucindezela afika ku-1100-1300 MPa (160-190 ksi).Leli banga alifanele ukusetshenziswa emazingeni okushisa angaphezu kuka-300º C (572º F) noma amazinga okushisa aphansi kakhulu.Ibonisa ukumelana nokugqwala okuhle endaweni esemkhathini kanye ne-dilute acid noma usawoti, uma kuqhathaniswa no-304, futhi iphakeme kune-ferritic steel 430.

Amabanga Okwelashwa Kokushisa kanye Nokwehluka Kokusebenza: Isici esihlukanisayo se17-4PHukuba lula kwayo ukulungisa amazinga wamandla ngokuhlukahluka kwezinqubo zokwelapha ukushisa.Ukuguqulwa ku-martensite kanye nokuqina kwemvula eguga kuyindlela yokuqala yokuqinisa.Amabanga ajwayelekile okwelapha ukushisa emakethe afaka i-H1150D, H1150, H1025, ne-H900.Amanye amakhasimende acacisa isidingo sezinto ezibonakalayo ezingu-17-4PH ngesikhathi sokuthenga, ezidinga ukwelashwa okushisa.Njengoba amamaki okwelapha ukushisa ehluka, izimo zokusetshenziswa ezihlukene kanye nezidingo zomthelela kufanele zihlukaniswe ngokucophelela.Ukwelashwa kokushisa kwe-17-4PH kuhilela izinyathelo ezimbili: ukwelashwa kwesixazululo nokuguga.Izinga lokushisa lokwelapha isixazululo liyafana ekupholiseni okusheshayo, futhi ukuguga kulungisa izinga lokushisa kanye nenani lemijikelezo yokuguga ngokusekelwe emandleni adingekayo.
Izicelo:
Ngenxa yezindawo zayo ezinhle kakhulu zokukwazi ukumelana nokugqwala, i-17-4PH isetshenziswa kakhulu ezimbonini ezifana namakhemikhali e-petrochemicals, amandla enuzi, i-aerospace, ezempi, olwandle, ezezimoto kanye nezinkundla zezokwelapha.Ngokuzayo, kulindeleke ukuthi kube nombono wemakethe othembisayo ofana ne-duplex steel.
