Inconel® 718 (Alloy 718) UNS N07718 Txuj:
Inconel 718 (Nickel 718) Sawb, Coil, Ntawv Nyiaj, Hlau, AMS 5596, AMS 5597, ASTM B670, WESTINGHOUSE NFD310021 (Nuclear), UNE N07718
piav
UNS N07718 yog nickel-chromium alloy nrog nag lossis daus hardenable zog thiab siab creep rupture lub zog ntawm qhov kub txog li 1300 degree F (700 degree). Lub hnub nyoog tsis zoo hardening teb ntawm Alloy 718 tso cai rau annealing thiab welding yam tsis muaj spontaneous hardening thaum cua sov thiab txias. Cov hlau muaj qhov zoo tshaj plaws weldability piv rau cov nickel-based superalloys hardened los ntawm txhuas thiab titanium.

Inconel® 718 (Alloy 718) UNS N07718 Heat Treatment Capabilities
Ob qhov kev kho cua sov feem ntau yog siv rau UNS N07718: kev daws teeb meem ntawm 1700-1850 degree F ua raws li kev ua kom txias sai, feem ntau hauv dej, ntxiv rau nag lossis daus hardening ntawm 1325 degree F rau 8 teev, qhov cub txias rau 1150 degree F, khaws cia ntawm Total Lub sijhawm laus yog 18 teev ntawm 1150 degree F, ces cua txias. Cov tshuaj yog annealed ntawm 1900 - 1950 degree F, ces txias sai heev, feem ntau yog nyob rau hauv dej, ntxiv rau nag lossis daus hardened ntawm 1400 degree F rau 10 teev, rauv txias rau 1200 degree F, tuav ntawm 1200 degree F rau tag nrho cov laus lub sij hawm. 20 teev, tom qab ntawd dhau los ntawm huab cua txias.
Kev kho cua sov
UNS N07718 tuaj yeem ua kom tawv los ntawm: lub hnub nyoog ua haujlwm txias txias ua haujlwm txias ua haujlwm raws li hnub nyoog hardening
