Hauv kev lag luam superalloys,Inconel 625 thiab 718yog ob tug loj players, tab sis lawv yog haum rau txawv daim ntaub ntawv. Rau kev yuav cov thawj coj thiab cov neeg tsim qauv, qhov teeb meem nyuaj tshaj plaws yog cov khoom siv tsis ua haujlwm vim ib puag ncig tsis sib haum.
Teeb meem:VimIb 625's lub koob npe nrov li "superalloy," nws raug xaiv rau siab -ceev rotating turbine shafts, tsuas yog pom tias nws deforms nyob rau hauv load.
Risk:Xaivib 718rau offshore brine reactors ua rau muaj kev puas tsuaj pitting corrosion nyob rau hauv lub hlis vim nws tsis tshua muaj tshuaj lom neeg muaj pes tsawg leeg piv rauIb 625.
Xaiv ntawmInconel 625 (UNS N06625) thiab Inconel 718 (UNS N07718)yog qhov tseem ceeb ntawm kev lag luam - tawm ntawm cov khoom thauj khoom thiab tshuaj lom neeg corrosion.
