Izakhiwo Ezibalulekile Zensimbi Engagqwali engu-17-4 PH
1.Amandla Ayingqayizivele: Iletha amandla ahlaba umxhwele asukela ku-1000 kuya ku-1400 MPa, okuyenza ibe ilungele izinhlelo zokusebenza ezinomthwalo omkhulu.
2.I-Superior Corrosion Resistance: Uma iqhathaniswa nensimbi engagqwali engu-304, nokho inikeza ukuvikeleka okuthuthukisiwe ekuqhekekeni kokucindezeleka-ukugqwala ezindaweni ezinokhahlo.
3.I-Flexible Heat Treatability: Izakhiwo zikagesi zingalungiswa ngokunembile ngezinqubo zokuqina kwemvula ezifana ne-H900, H1025, ne-H1150.
4.Ukuqina Okuvelele: Igcina ubuqotho besakhiwo ngisho nangaphansi kwamazinga okushisa aphezulu nezimo zesevisi eziyinselele.
Ukwelashwa Kokushisa kanye Nokuqina Kwemvula
Okuhlukanisa ngo-17-4 PH insimbi engagqwali amandla ayo amangalisayo okwenza imvula ibe lukhuni—inqubo yokwelapha ukushisa ethuthukisa kakhulu ukusebenza kwayo komshini. Ngokushisisa ingxubevange emazingeni okushisa anembayo alandelwa ukuguga okulawulwayo, izakhiwo zayo zingacushwa kahle.Izimo ezijwayelekile eziphethwe ukushisa zihlanganisa:
• I-H900: Inikeza amazinga aphezulu wamandla.
• I-H1150: Inikeza ukumelana nokugqwala okuphakeme nokuqina okukhulayo.
Lokhu kuzivumelanisa nezimo kwenza onjiniyela bakwazi ukuhlanganisa izici zezinto ezibonakalayo ukuze bahlangabezane nezidingo ezithile zezinhlobonhlobo zezinhlelo zokusebenza zezimboni.
Izicelo ze-17-4 PH Stainless Steel
Izakhiwo eziphakeme zensimbi engagqwali engu-17-4 PH ziyenza ilungele uhla olubanzi lwezinhlelo zokusebenza:
• I-Aerospace: Isetshenziswa emibuthanweni yesakhiwo, izingxenye ze-turbine, nezixhumi ezisebenza kahle kakhulu.
• Inkambu Yezokwelapha: Ilungele amathuluzi okuhlinza anembayo kanye nemishini yokufakelwa eqinile.
• Ukucutshungulwa Kwamakhemikhali: Kusetshenziswa kuma-reactor namathuluzi abekezelela ukuchayeka kumakhemikhali anolaka.
• Uwoyela Negesi: Kuvamile kuma-pump shafts, amavalvu, nezinye izingxenye ezingaphansi kwengcindezi ephezulu kanye nemithombo yezindaba ebolayo.
• Umkhakha Wezokuvikela: Wethembekile ekukhiqizeni izingxenye eziqinile kuhardware yezinga lezempi.
Lezi zinhlelo zokusebenza zigcizelela ukwethembeka kwazo ezindaweni eziyinselele lapho kokubili amandla nokuphila isikhathi eside kubalulekile.
Kungani Khetha i-17-4 PH Stainless Steel?
I-17-4 PH insimbi engagqwali iba yisixazululo esithandwayo lapho izicelo zibiza:
• Amandla emishini akhethekile okumelana nemithwalo esindayo kanye nengcindezi.
