♦Khoom siv: Alloy A286 (UNS 66286)
♦Loj: M10-M120
♦Qib: AAA Qib
♦Peb tsim thiab muab a286 Alloy ntsia liaj qhov rooj, Ntsia Hlau, Ceev raws li thoob ntiaj teb cov qauv loj kuj tuaj yeem tsim raws li cov neeg siv khoom kos duab
Incoloy A286yog Fe-25Ni-15Cr raws li superalloy ntxiv dag zog los ntawm kev sib ntxiv ntawm molybdenum, titanium, aluminium, vanadium thiab kab boron. Nyob rau hauv 650 ℃, nws muaj siab yield zog, ruaj thiab creep zog, zoo ua plasticity thiab txaus siab vuam kev ua tau zoo. haum rau kev tsim cov kub kub bearing qhov chaw ntawm aero-engines ua hauj lwm nyob rau hauv 650 ℃ rau ib ntev lub sij hawm, xws li turbine disc, xovxwm disc, rotor hniav thiab fastener, thiab lwm yam.The alloy yuav siv tau los tsim deformation khoom ntawm ntau yam duab, xws li daim hlau, forgings, daim hlau, rods, xov hlau thiab annular qhov chaw.
