Hauj lwm lawm
Nickel alloy 718
Alloy 718 (UNS N07718/W.Nr. 2.4668)yog lub zog siab, corrosion-resistant nickel-chromium khoom siv ntawm -423 degree rau 1300 degree F.
Lub hnub nyoog-hardenable alloy tau yooj yim fabricated, txawm nyob rau hauv complex qhov chaw. Nws cov yam ntxwv welding, tshwj xeeb tshaj yog nws tsis kam mus rau tom qab vuam tawg, yog qhov zoo heev.
Qhov yooj yim thiab kev lag luam uas INCONEL alloy 718 tuaj yeem tsim tau, ua ke nrog zoo tensile, qaug zog, creep, thiab rupture lub zog, tau ua rau nws siv nyob rau hauv ntau yam kev siv. Piv txwv ntawm cov no yog cov khoom siv rau cov kua roj foob pob hluav taws, lub nplhaib, cov khoom siv, thiab ntau yam ntawv hlau tsim rau cov dav hlau thiab cov av-raws li cov roj turbine xyaw, thiab cov tankage cryogenic. Nws kuj yog siv rau fasteners thiab instrumentation qhov chaw.

CORROSION RESISTANCE
INCONEL alloy 718 muaj corrosion kuj zoo heev rau ntau yam xov xwm. Qhov kev tiv thaiv no, uas zoo ib yam li lwm cov nickel-chromium alloys, yog ib txoj haujlwm ntawm nws cov muaj pes tsawg leeg. Nickel pab txhawb rau corrosion kuj nyob rau hauv ntau inorganic thiab organic, uas tsis muaj zog oxidizing, tebchaw thoob plaws ntau yam ntawm acidity thiab alkalinity. Nws kuj tseem muaj txiaj ntsig zoo hauv kev tawm tsam chloride-ion kev ntxhov siab-corrosion tawg. Chromium imparts muaj peev xwm tiv thaiv kev tawm tsam los ntawm oxidizing media thiab sulfur compounds. Molybdenum paub tias yuav pab tiv thaiv pitting nyob rau hauv ntau yam xov xwm.
Muaj cov khoom siv thiab cov lus qhia tshwj xeeb
INCONEL alloy 718 yog tsim los ntawm UNS N07718, UNS N07719, thiab Werkstoff Nr. 2.4668 ib. Nws muaj npe hauv NACE MR01-75 rau kev pabcuam roj thiab roj. Alloy 718 yog muaj nyob rau hauv cov yeeb nkab, raj, ntawv, sawb, phaj, puag ncig bar, tiaj tus bar, forging Tshuag, hexagon, hlau thiab extruded seem.
