Hastelloy C-4
Tlhaloso e Khutšoanyane:
Hastelloy C-4 (UNS NO6455)
Hastelloy C-4 Likarolo le Kakaretso ea Likopo:
Alloy ke motsoako oa austenitic low-carbon nickel-molybdenum-chromium alloy. Phapang e ka sehloohong pakeng tsa Nicrofer 6616 hMo le li-alloys tse ling tsa lik'hemik'hale tse tšoanang tse entsoeng pejana ke carbon e tlaase, silicon, tšepe le tungsten. Sebopeho sena sa lik'hemik'hale se fana ka botsitso bo babatsehang ho 650-1040 ° C le ho ntlafala ho hanyetsa ho bola ha intergranular, ho qoba ho ba le monyetla oa ho senya le ho senya HAZ tlas'a maemo a loketseng a tlhahiso. Alloy e sebelisoang lits'ebetsong tsa flue gas desulfurization, pickling le acid regeneration plant, acetic acid le tlhahiso ea lik'hemik'hale tsa temo, tlhahiso ea titanium dioxide (mokhoa oa chloride), electrolytic plating.
