I-Incons 718 iqukethe ngokuyinhloko i-nickel (52%). Izakhi zezabelo zifaka i-iron (19%), i-chromium (18%), i-niobium + tantalum (5%), i-aluminium (0.5%), ngaphezu kwezinye izindlela zokulandela umkhondo njengeBaron, iCobalt, i-MANnganese kanye ne-Silicon.

I-Inxotemensi 718 Alloy yayikhethwe ngokuyinhloko ngonjiniyela bokuqamba amandla ayo aphezulu ezimweni zokushisa ezedlulele kuwo womabili ama-Exs of the Spectrum. Ingasetshenziswa kusuka emazingeni okushisa aphansi yonke indlela eya ku-1300¡Ãf \ 704¡Ãc. Ibonisa isivuno esiphakeme kakhulu, i-Tensile ne-creep drupties yokwephungula kulo lonke uhla lonke. Iphinde ikhombise amandla amahle kakhulu we-Tensile kanye nomthelela.

I-Hastelloy C276 yaziwa ngokumelana kwayo okuhle kakhulu kokugqwala kwemidiya ehlukahlukene. Kubandakanya i-chloride ion, amakhompiyutha esibabule, njll. Ngaphezu kwalokho, le alloy inokumelana kahle nokugqwala kwama-crevice, ukugqwala okukhonkotha kanye nokuqhekeka kokugqwala kwengcindezi. Kuyasiza ukumelana nemiphumela elonakalisayo ye-chlorine emanzi, i-chlorine dioxide ne-hypochlorite. Lo mkhiqizo ulungele izinhlelo zokusebenza zamanzi olwandle.

I-C276 yakhiwa phakathi kuka-2250 \ 750 1230 \ 955oC) bese ifakwe emazingeni okushisa okushisa imizuzu engama-30 noma i-INGOT Isigaba Sokubucayi. Ukwenza kufanele kuqale ngokushesha, imali ekhokhiswayo isuswa esithandweni sokuhlaziywa kabusha, ukuncishiswa okungu-25 \ 40% kusiza ekutholeni ukushisa okungaphakathi ngangokunokwenzeka. Ukuze uthole ukumelana okuphezulu kokugqwala, izingxenye ezakhiwe kufanele zinqanyulwe kamuva. Bona ukwelashwa okushisa.

I-Hastelloy iyinhlangano ye-nickel engamelana ne-cororion equkethe ezinye izinto zamakhemikhali ezifana ne-chromium ne-molybdenum. Lokhu okuqukethwe kunokumelana okuphezulu kokushisa kanye nokuphikiswa okuhle kakhulu kokugqwala. I-Hastelloy C276 ingenye yamabanga aseHastelloy asetshenziswa embonini kawoyela negesi.

I-Alloy 600 \ I-Incontel 600 iyinhlanganisela ye-nickel chromium ne-iron enikeza impahla ejwayelekile embonini yamakhemikhali kanye nenjini yezimoto, injini ye-AERHO NE-AIRFrame. Ukwakheka okulawulwayo kwamakhemikhali kukhawulelwe ukusetshenziswa embonini yenuzi ukuqeda ubungozi bokuqhekeka kokuphazamiseka kokuqhekeka emanzini ahlanzeke kakhulu aqukethe ama-chloride ion.

Ukuguquguquka kwamanye amazwe kwe-Incon 600 Alloy kuyakuvumela ukuthi kusetshenziswe ezinhlobonhlobo zezicelo ezibandakanya amazinga okushisa aqhamuka emazingeni okushisa ama-cryogenic kuya ngaphezulu kwe-2000¡Ãf (1095¡Ãc (1095¡Ãc (1095¡Ãc).

Le alloy isetshenziswa kabanzi embonini yamakhemikhali ngamandla ayo nokuphikiswa kokugqwala. Izicelo zifaka ama-heater, namanje, amakholomu bubble, kanye nama-condenser ngokusebenza kwamafutha acid; Amashubhu we-Evaporator, amashidi we-tube, kanye namathrayidi aqediwe wokwenziwa kwe-sodium sulfide; nemishini yokucubungula i-abitic acid ekukhiqizeni i-pulp.

I-Alloy X yaziwa ngamandla ayo okushisa aphezulu kakhulu futhi ingamelana namazinga okushisa aze afike ku-2200¡ãf. I-alloy nayo ingahlelwa kalula ngezindlela zezincwadi nezizenzakalelayo ngokwakhiwa kanye nezakhiwo ze-welding. Ngaphezu kwalokho, i-Hastelloy X imelana nokugqwala, ukushisa kanye noxidation futhi ingamelana nokunciphisa noma ukungathathi hlangothi kanye ne-oxidation.

Ama-Superlloys ane-oxidation enhle nokumelana nokumelana okuhle futhi angaqiniswa ngezindlela ezinjengokuqina kwezulu, ikhambi lokuqina futhi usebenze kanzima. Bangasebenza futhi ngaphansi kwengcindezi emishini ephezulu kanye nokushisa okuphezulu nalapho kudingeka khona ukuqina komhlaba okuphezulu.
