760 MPA Mos Kub Kub N07718 Nickel Alloy Inconel Steel
Kev piav qhia dav dav
Inconel 718 yog ib lub hnub nyoog-hardenable alloy uas yog heev corrosion resistant. Nws lub zog siab, corrosion kuj, thiab yooj yim ntawm weld fabrication tau ua alloy 718 qhov nrov tshaj plaws superalloy siv hauv kev lag luam.
Inconel 718 muaj kev tiv thaiv zoo rau cov organic acids, alkalies thiab ntsev, thiab dej hiav txwv. Kev ua haujlwm ncaj ncees rau sulfuric, hydrochloric, hydrofluoric, phosphoric, thiab nitric acids. Zoo heev rau oxidation, carburization, nitridation, thiab molten ntsev. Ncaj tsis kam rau sulfidation.
Hnub nyoog-hardenable Inconel 718 ua ke nrog lub zog kub txog li 700 ° C (1300 ° F) nrog corrosion kuj thiab zoo heev fabricability. Nws cov yam ntxwv welding, tshwj xeeb tshaj yog nws tsis kam rau postweld cracking, yog qhov zoo heev. Vim yog cov cwj pwm no, Inconel 718 yog siv rau qhov chaw rau lub dav hlau turbine cav; high-speed airframe qhov chaw, xws li lub log, thoob, thiab spacers; high-temperature bolts thiab fasteners, cryogenic tankage, thiab Cheebtsam rau roj thiab roj extraction thiab nuclear engineering.
