HASTELLOYC4ke motsoako o entsoeng ka nickel, chromium, le molybdenum. E nkoa e le motsoako o feto-fetohang ka ho fetisisa bakeng sa ho loantša mafome. Motsoako ona o bontša ho hanyetsa ho thehoa ha li-precipitate tsa moeli oa lijo-thollo ha li chesetsoa mocheso, e leng se etsang hore e lokele lits'ebetso tse fapaneng tsa ts'ebetso ea lik'hemik'hale boemong ba eona ba ho tjheseletsa. Ho feta moo, Alloy C4 e bontša ho hanyetsa ho ikhethang ho ho taboha ha sekoti, ho petsoha ha khatello le mafome, le sepakapaka se etsang oxidize ho fihlela ho 1900°F. E na le khanyetso e ikhethang ho mefuta e mengata ea libaka tsa lik'hemik'hale.
LIKOPELO:
1. Indasteri ea pampiri: Li-digesters le limela tsa bleach.
2. Tikoloho ea khase e bolila: Likarolo tse pepesehetseng khase e bolila.
3. Difeme tsa ho tlosa sebabole ka khase e flue: Disebediswa tse sebediswang difeme tsa ho tlosa sebabole ka khase e flue.
4. Tikoloho tsa asiti ya sulfuriki: Di-evaporator, di-heat exchanger, di-filters, le di-mixer tse sebediswang ditikolohong tsa asiti ya sulfuriki.
5. Li-reactor tsa asiti ea sulfuric: Lisebelisoa tse sebelisoang li-reactor tsa asiti ea sulfuric.
6. Ts'ebetso ea chloride ea tlhaho: Lisebelisoa tse sebelisoang ts'ebetsong ea chloride ea tlhaho.
7. Mekhoa ea ho etsa li-catalyst tsa halide kapa asiti: Lisebelisoa tse sebelisoang lits'ebetsong tse sebelisang li-catalyst tsa halide kapa asiti.
