Amavuta ya HastelloyC ni Ni-Cr-Molybdenum-Tungsten ivanze itanga uburyo bwiza bwo kurwanya ruswa muri rusange kurusha izindi Ni-Cr-Molybdenum-Hastelloy C276, C4 na 625.
Amavuta ya Hastelloy C afite imbaraga zo kurwanya imyobo, kwangirika kwangirika no guturika.
Ifite imbaraga zo kurwanya okiside itangazamakuru ryamazi, harimo chlorine itose, aside nitric cyangwa uruvange rwa aside irike irimo ioni ya chloride.
Muri icyo gihe, ibinyobwa bya Hastelloy C nabyo bifite ubushobozi bwiza bwo kurwanya kugabanuka no gukwirakwiza ibidukikije byahuye nabyo mugihe cyibikorwa.
Hamwe nubu buryo bwinshi, burashobora gukoreshwa mubidukikije bitera ibibazo, cyangwa mu nganda kubikorwa bitandukanye byo gukora.
Amavuta ya Hastelloy C afite imbaraga zidasanzwe zo kurwanya ibidukikije bitandukanye, harimo ibintu bikomeye bya okiside, nka chloride ferric, chloride y'umuringa, chlorine, umuti w’umwanda w’umuriro (organic or organic), acide formic, acide acike, anhydride ya acetike, amazi yinyanja hamwe numuti wumunyu.
Amavuta ya Hastelloy C afite ubushobozi bwo kurwanya imvura igwa ku mbibi z’imvura muri zone yibasiwe n’ubushyuhe, ibyo bigatuma ibera ubwoko bwinshi bwimiti ikoreshwa muburyo bwo gusudira.

1.Kurwanya ruswa ya acide sulfurike yumuti wibintu byose kugeza 70 ℃, igipimo cya ruswa hafi 0.1mm / a.
2.Igipimo cyo kwangirika kwubwoko bwose bwa acide hydrochloric acide ntabwo iri hejuru ya 0.1mm / a mubushyuhe bwicyumba, munsi ya 0.5mm / a kugeza kuri 65 ℃ .Umwuka wa ogisijeni wuzuza aside hydrochlorike ugira uruhare mukurwanya ruswa.
3.Igipimo cya ruswa kiri munsi ya 0,25mm / a muri aside hydrofluoric, hejuru ya 0,75mm / a mubihe bya 55% H3PO4+ 0.8% HF mubushyuhe butetse.
4.Kurwanya ruswa kugirango igabanye aside nitricike yibitekerezo byose mubushyuhe bwicyumba cyangwa ubushyuhe bwo hejuru, igipimo cyayo ni nka 0.1mm / a, irwanya ruswa nziza yibintu byose bya acide chromic na acide organic nibindi bivanga kugeza 60 kugeza 70 and, na igipimo cya ruswa kiri munsi ya 0.125mm / a na 0.175mm / a.
5.Bimwe mubikoresho bike bishobora kurwanya ruswa ya chlorine yumye kandi itose, irashobora gukoreshwa mugihe cya ruswa ihinduranya gaze ya chlorine yumye kandi itose.
6.Kurwanya gaze ya HF yubushyuhe bwo hejuru, igipimo cya ruswa ya gaze ya HF ni 0.04mm / a kugeza 550 ℃, 0.16mm / a kugeza 750 ℃.
