AMS 5663 Inconel 718 cov khoom siv chaw tsim khoom,tiv tauj pebkom tau txais kev tsocai dawb thiab qauv!
Hauv kev lag luam aerospace thiab lub zog, cov khoom siv kev ntseeg siab yog lub hauv paus ntawm kev ua haujlwm zoo tshaj plaws.TIAB SA 5663yog qhov tseem ceeb aerospace khoom specification rauib 718(Alloy 718), txhais cov kev xav tau ntawm cov khoom siv hauv nws cov kev daws teeb meem - kho thiab nag lossis daus- mob hnyav.
AMS 5663 Specification yog dab tsi?
TIAB SA 5663yog ib qib siab - cov txheej txheem cov ntaub ntawv luam tawm los ntawm SAE International. Nws tshwj xeeb npog npib tsib xee- alloy tuav, forgings, rings, thiab Tshuag npaj rau cov khoom uas yuav tsum tau muaj zog thiab oxidation tsis kam.
