Hauv kev xav tau ntawm aerospace propulsion thiab siab -voltage zog tshuab,hwv 4169yog vajntxwv uas tsis muaj kev sib cav. Raws li kev lees paub thoob ntiaj teb kev sib npaug ntawmInconel 718 (UNS N07718 / 2.4668), no nag lossis daus -nickel hardening-chromium alloy tau hloov kho niaj hnub engineering.
Vim li cas nws thiaj li zoo heev?Vim nws tuav lub zog tshwj xeeb ntawm qhov kub thiab txias siab li650℃(1200℃F), thaum tseem nthuav tawm superior weldability piv rau lwm yam siab - kub alloys. Rau cov neeg tsim qauv,hwv 4169muab "zero-kev pheej hmoo" kev daws teeb meem rau cov khoom siv uas yuav tsum tiv taus cov khoom siv hluav taws xob loj thiab cov thermal loads.
