HASTELLOYC4waa daawaha ka kooban nikkel, chromium, iyo molybdenum. Waxaa aad loogu tixgaliyaa inay tahay daawaynta ugu badan ee la dagaallanka daxalka. Daawaha Tani waxay muujinaysaa iska caabin ah in formation of hadhuudh soohdinta soo da'aya marka lagu sakhiray kulaylka alxanka, taasoo ka dhigaysa mid ku haboon codsiyada hababka kiimikada kala duwan ee ay xaalad alxanka. Intaa waxaa dheer, AlloyC4waxay muujisaa iska caabin heersare ah oo u adkaysta godadka, dildilaaca-daxalka, iyo hawada oksaydhaynta ilaa 1900°F. Waxay leedahay iska caabin gaar ah oo ay u leedahay deegaan kiimiko oo kala duwan.
CODSIGA:
1.Warshad waraaqo ah: Dheejiyeyaasha iyo dhirta warankiilada.
2. Bey'adaha gaaska dhanaan: Qaybaha soo gaadhay gaaska dhanaan.
3.Flue-gas desulfurization dhirta: Qalabka loo isticmaalo dhirta desulfurization flue-gas.
