I-17-4ph Halloy iyinhlangano yemvula - inzima, i-martensitic yensimbi engenacala eyakhiwe ngethusi, i-niobium, ne-tantalum. Izici: Ngemuva kokwelashwa okushisa, umkhiqizo ukhombisa izici ezithuthukisiwe zemishini, uzuze amandla acindezelayo afinyelela ku-1100-1300 MPA (160-190 KSI). Leli banga alifanele ukusetshenziswa emazingeni okushisa adlula amazinga okushisa adlula ama-300º c (572º f) noma amazinga okushisa aphansi kakhulu. Kukhombisa ukumelana kahle kokugqwala emkhathini nasekunciphiseni i-acid noma ezindaweni ezisawoti, kuqhathaniswa nama-304, futhi kunophakeme kune-Ferrititic Steel 430.
17-4phI-Alloy iyindlela yokuqina yemvula - enzima, i-martensitic yensimbi eyakhiwe ngethusi, i-niobium, ne-tantalum.

Kukhombisa ukumelana kahle kokugqwala emkhathini nasekunciphiseni i-acid noma ezindaweni ezisawoti, kuqhathaniswa nama-304, futhi kunophakeme kune-Ferrititic Steel 430.
Ukushisa amamaki kanye nokuhlukaniswa kokusebenza: Isici esihlukanisayo se17-4phIngabe ukukhululeka kwamazinga okulungisa amandla ngokuhlukahluka kwezinqubo zokwelashwa kokushisa. Ushintsho ku-Martensite kanye nokuqina kwethala kuyindlela eyinhloko yokuqiniswa. Amamaki okushisa ajwayelekile emakethe afaka i-H1150D, H1150, H1025, ne-H900.Amanye amakhasimende acacisa isidingo sezinto ezi-17-4ph ngesikhathi sokuthengwa kwempahla, edinga ukwelashwa okushisa. Njengoba amamaki okushisa avutha ahlukahlukene, izimo zokusetshenziswa ezahlukahlukene kanye nezidingo ezinomthelela kumele zihlukaniswe ngokucophelela.Indlela yokushisa ka-17 -4ph kufaka izinyathelo ezimbili: Isixazululo sokwelashwa kwesisombululo kanye nokuguga. I-Solution Treatment Temperature iyafana ngokupholisa okusheshayo, kanye nokuguga kuguqula izinga lokushisa kanye nenombolo yemijikelezo yokuguga esuselwa emandleni adingekayo.
Izicelo:
Ngenxa yezakhiwo zayo zokungamelana kahle nemishini yokulwa nokugqwala, 17-4ph isetshenziswa kabanzi ezimbonini ezifana nama-petrochemicals, amandla enuzi, ama-aerospace, amasosha amasosha, izimoto, kanye nezokwelapha. Esikhathini esizayo, kulindeleke ukuthi kube nokubuka kwemakethe okuthembisayo okufana ne-Duplex Steel.
