I-17-4PH i-alloy yi-precipitation-hardening, i-martensitic stainless steel eyenziwe ngobhedu, i-niobium, kunye ne-tantalum.Iimpawu: Emva kokunyanga ubushushu, imveliso ibonisa iipropathi eziphuculweyo zomatshini, ukufezekisa amandla oxinzelelo ukuya kwi-1100-1300 MPa (160-190 ksi).Eli bakala alifanelekanga ukusetyenziswa kumaqondo obushushu angaphezu kwe-300º C (572º F) okanye amaqondo aphantsi kakhulu.Ibonisa ukuxhathisa okulungileyo kokuhlwa kwi-atmospheric kunye ne-asidi edibeneyo okanye indawo yetyuwa, xa ithelekiswa ne-304, kwaye iphezulu kune-ferritic steel 430.
17-4PHingxubevange yimvula-eqinisayo, intsimbi ye-martensitic eyenziwe ngobhedu, i-niobium, kunye ne-tantalum.Iimpawu: Emva kokunyanga ubushushu, imveliso ibonisa iipropathi eziphuculweyo zomatshini, ukufezekisa amandla oxinzelelo ukuya kwi-1100-1300 MPa (160-190 ksi).Eli bakala alifanelekanga ukusetyenziswa kumaqondo obushushu angaphezu kwe-300º C (572º F) okanye amaqondo aphantsi kakhulu.Ibonisa ukuxhathisa okulungileyo kwe-corrosion kwi-atmospheric kunye ne-asidi edibeneyo okanye indawo yetyuwa, xa ithelekiswa ne-304, kwaye iphezulu kune-ferritic steel 430.
AmaBanga oNyango loBubushushu kunye neNtsebenzo yeNtsebenzo: Uphawu olwahlulayo lwe17-4PHkukulula kwayo ukulungelelanisa amanqanaba amandla ngokuhlukahluka kwiinkqubo zonyango lobushushu.Inguqu kwi-martensite kunye nokuqina kwemvula egugayo zezona ndlela ziphambili zokuqinisa.Amabanga aqhelekileyo onyango lobushushu kwiimarike abandakanya i-H1150D, i-H1150, i-H1025, kunye ne-H900.Abanye abathengi bacacisa imfuno yezinto ze-17-4PH ngexesha lokuthengwa, ezifuna unyango lokushisa.Njengoko amabakala okunyanga ukushisa ahluka, iimeko ezahlukeneyo zokusetyenziswa kunye neemfuno zempembelelo kufuneka zihlulwe ngokucophelela.Unyango lokushisa kwe-17-4PH lubandakanya amanyathelo amabini: unyango lwesisombululo kunye nokuguga.Ubushushu bonyango lwesisombululo bufana nokupholisa ngokukhawuleza, kunye nokuguga kulungelelanisa ubushushu kunye nenani lemijikelo yokuguga esekelwe kumandla afunekayo.
Usetyenziso:
Ngenxa yeepropathi zayo ezigqwesileyo zoomatshini kunye ne-corrosion-resistant, i-17-4PH isetyenziswa kakhulu kumashishini afana neekhemikhali zepetroli, amandla enyukliya, i-aerospace, emkhosini, elwandle, ezeemoto, nakwimimandla yezonyango.Kwixesha elizayo, kulindeleke ukuba ibe nembono yemarike ethembisayo efana nentsimbi ye-duplex.
