Waspaloy yog ib lub hnub nyoog npib tsib xee hardenable superalloy nrog zoo kub kub lub zog thiab zoo corrosion kuj, tshwj xeeb tshaj yog rau oxidation, ntawm kev pab cuam kub txog li 1200 ° F (650 ° C) rau cov ntaub ntawv tseem ceeb rotating, thiab mus txog 1600 ° F (870 ° C. ) rau lwm yam, tsawg demanding, daim ntawv thov.Lub alloy lub siab kub lub zog yog muab los ntawm nws cov khoom muaj zog cov ntsiab lus, molybdenum, cobalt thiab chromium, thiab nws cov hnub nyoog hardening ntsiab, txhuas thiab titanium.Nws lub zog thiab kev ruaj ntseg ntau dua li cov feem ntau muaj rau alloy 718.

Hnub nyoog hardening tshwj xeeb npib tsib xee-raws li alloy, muaj zog zoo nyob rau hauv 1400-1600 ° F.Zoo tsis kam rau oxidation siv nyob rau hauv roj turbine cav ntawm 1400-1600 ° F cua.Nyob rau hauv 1150-1150 ° F, Waspaloy creep rupture zog yog siab tshaj nyob rau hauv 718.
Ntawm qhov ntsuas ntawm 0-1350 ° F, kub tensile zog rau lub sij hawm luv luv yog phem tshaj 718 alloy
Waspaloy yog siv rau cov roj turbine engine Cheebtsam uas hu rau lub zog loj thiab corrosion kuj ntawm kev khiav hauj lwm kub.Tam sim no thiab muaj peev xwm siv xws li compressor thiab rotor discs, shafts, spacers, seals, rings thiab casings,fasteners thiab lwm yam khoom siv hluav taws xob sib txawv, airframe assemblies thiab missile systems.
