Alloy 617 yog ib qho kev daws teeb meem, npib tsib xee-chromium-cobalt-molydenum alloy nrog kev sib xyaw tshwj xeeb ntawm lub zog kub kub thiab oxidation tsis kam.Lub alloy kuj muaj kev tiv thaiv zoo heev rau ntau qhov chaw corrosive, thiab nws tau yooj yim tsim thiab welded los ntawm cov txheej txheem pa.Lub siab nickel thiab chromium cov ntsiab lus ua rau cov alloy resistant rau ntau yam ntawm ob qho tib si txo thiab oxidizing xov xwm.Cov txhuas, ua ke nrog cov chromium, muab oxidation tsis kam ntawm qhov kub thiab txias.Kev daws teeb meem muaj zog yog muab los ntawm cobalt thiab molydenum.

Alloy nyob rau hauv lub tshav kub corrosion ib puag ncig xws li sulfide, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig mus txog 1100 ℃ circulating oxidation thiab carbonization, muaj zoo heev corrosion kuj.Qhov corrosion kuj ua ke nrog zoo heev mechanical zog, ua rau nws tshwj xeeb tshaj yog haum rau high kub teb.zoo transient thiab lub sij hawm ntev mechanical zog mus txog 1100 ° C.
Kev sib xyaw ua ke ntawm lub zog siab thiab oxidation tsis kam ntawm qhov kub siab tshaj 1800 ° F ua rau alloy 617 yog ib qho khoom siv zoo nkauj rau cov khoom xws li ducting, combustion cans, thiab transition liner nyob rau hauv ob lub dav hlau, thiab av raws li roj turbines.Vim nws tsis kam mus rau qhov kub-kub corrosion, alloy yog siv rau catalyst-grid txhawb nyob rau hauv zus tau tej cov nitric acid, rau tshav kub-kho baskets, thiab txo cov nkoj hauv refining molybdenum.Alloy 617 kuj muaj cov khoom txaus nyiam rau cov khoom siv hluav taws xob tsim hluav taws xob, ob qho tib si fossil-fueled thiab nuclear.
