Hastelloy C-4
Ibisobanuro bigufi:
Hastelloy C-4 (UNS NO6455)
Hastelloy C-4 Ibiranga hamwe na Porogaramu Incamake:
Amavuta ni austenitike make-karubone nikel-molybdenum-chromium.Itandukaniro nyamukuru hagati ya Nikrofer 6616 hMo nandi mavuta avanze yimiti isa mbere yakozwe ni karubone nkeya, silikoni, fer na tungsten.Iyi miti itanga imiti ihamye kuri 650-1040 ° C kandi ikarwanya kurwanya ruswa hagati y’umubiri, irinda kwangirika kwangirika kwangirika no kwangirika kwa HAZ mugihe gikwiye cyo gukora.Amavuta akoreshwa muri sisitemu ya gaz desulfurisiyasi, uruganda rutunganya aside na acide, acide acetike hamwe n’imiti ikomoka ku buhinzi, umusaruro wa dioxyde de titanium (uburyo bwa chloride), gufata amashanyarazi.
Hastelloy C-4 Ibiranga bisa:

Ibikorwa bya Hastelloy C-4 nibisabwa:
1. n'umwanda.Hasi ya sulfure yibiri muri lisansi nibyiza, ibirimo sulfure ya gaze naturel igomba kuba munsi ya 0.1%, sulfure yamavuta aremereye igomba kuba munsi ya 0.5%.Gushyushya itanura ry'amashanyarazi ni amahitamo meza, kubera ko itanura ry'amashanyarazi rishobora kugenzura neza ubushyuhe kandi gaze y'itanura ikagira isuku.Niba gaze ya gaze ya gaz isukuye bihagije, urashobora guhitamo.
2, ivanga ubushyuhe bwo gutunganya ubushyuhe buri hagati ya 1080 ℃ ~ 900 ℃, uburyo bwo gukonjesha bwo gukonjesha amazi cyangwa ubundi bukonje bwihuse.Kugirango habeho kurwanya ruswa neza, kuvura ubushyuhe bigomba gukorwa nyuma yo kuvura ubushyuhe.
