I-alloy ye-17-4PH yintsimbi engagqwaliyo ye-martensitic eyenziwe ngobhedu, i-niobium, kunye ne-tantalum. Iimpawu: Emva konyango lobushushu, imveliso ibonisa iimpawu zoomatshini eziphuculweyo, ifikelela kumandla okucinezelwa ukuya kuthi ga kwi-1100-1300 MPa (160-190 ksi). Olu hlobo alufanelekanga ukusetyenziswa kumaqondo obushushu angaphezulu kwe-300º C (572º F) okanye kumaqondo obushushu aphantsi kakhulu. Ibonisa ukumelana okuhle nokugqwala kwiindawo ezinomoya kunye ne-asidi okanye ityuwa enyibilikisiweyo, efana ne-304, kwaye ingcono kunentsimbi ye-ferritic 430.
17-4PHI-alloy yintsimbi engenasici ye-martensitic eqina ngokwemvula, eyenziwe ngobhedu, i-niobium, kunye ne-tantalum.

Amanqanaba okuNyangwa koBushushu kunye noKwahluka kokusebenza: Uphawu olwahlulayo lwe17-4PHyindlela elula yokulungisa amanqanaba amandla ngokusebenzisa iindlela ezahlukeneyo zonyango lobushushu. Utshintsho kwi-martensite kunye nokuguga kokuqina kwemvula zezona ndlela ziphambili zokuqinisa. Amanqanaba aqhelekileyo onyango lobushushu kwimarike aquka i-H1150D, i-H1150, i-H1025, kunye ne-H900.Abanye abathengi bachaza imfuneko yezinto eziyi-17-4PH ngexesha lokuthenga, nto leyo efuna unyango lobushushu. Njengoko amanqanaba onyango lobushushu ahluka, iimeko ezahlukeneyo zokusetyenziswa kunye neemfuno zempembelelo kufuneka zahlulwe ngononophelo. Unyango lobushushu lwe-17-4PH lubandakanya amanyathelo amabini: unyango lwesisombululo kunye nokuguga. Ubushushu bonyango lwesisombululo buyafana ekupholiseni ngokukhawuleza, kwaye ukuguga kulungisa ubushushu kunye nenani lemijikelo yokuguga ngokusekelwe kumandla afunekayo.
Izicelo:
Ngenxa yeempawu zayo ezintle zoomatshini kunye nokumelana nokugqwala, i-17-4PH isetyenziswa kakhulu kumashishini afana neekhemikhali zepetroli, amandla enyukliya, inqwelo moya, umkhosi, ulwandle, iimoto, kunye namacandelo ezonyango. Kwixesha elizayo, kulindeleke ukuba ibe nembono yemarike ethembisayo efana nentsimbi ye-duplex.
