Inconel 718 yog dab tsi?
Cov khoom siv tseem ceeb rau Inconel 718 yog UNS N07718, nrog rau lwm cov npe xws li W.Nr. 2.4668 (Werkstoff) thiab ntau yam AMS (Aerospace Material Specification) cov lej xws li AMS 5662, 5663, lossis 5596, nyob ntawm daim ntawv thiab mob (xws li, bar, ntawv, forged).
Cov khoom siv twg yog 2.4668 sib npaug?
Khoom siv 2.4668 (Werkstoff Nr. 2.4668) yog German tus qauv tsim rau siab - zog, corrosion-resistant Nickel Alloy 718, tseem hu ua Inconel 718, nrog rau UNS lub npe N07718, dav siv nyob rau hauv aerospace thiab roj / roj rau siab{7.}
Dab tsi yog cov qauv rau Inconel 718?
Inconel 718 tus qauv qhia nws cov muaj pes tsawg leeg (nickel-chromium- hlau superalloy, muaj niobium/titanium) thiab cov khoom, thiab yog tswj los ntawm cov koom haum xws li ASTM, SAE (AMS 5662/5663), API, thiab NACE. Cov qauv no txhais tau tias nws lub zog muaj zog (tsawg kawg tensile lub zog 1275 MPa, yield zog 1034 MPa), corrosion tsis kam (ua haujlwm rau qaub roj corrosion), siab - kub creep zog (txog li 700 degree), thiab ua cov txheej txheem (kev kho thiab hnub nyoog hardening tshav kub kev kho mob), ua rau nws haum rau aerospace thiab roj thiab roj thiab roj.
