♦I-Material: Ingxubevange A286( UNS 66286)
♦Usayizi: M10-M120
♦Ibanga: AAA Ibanga
♦Sikhiqiza futhi Sinikezela ngebhawodi ye-a286 Alloy, Isikulufu, Amantongomane njengosayizi wezindinganiso zamazwe omhlaba nawo angakhiqiza njengomdwebo wamakhasimende ngamunye.
I-Incoloy A286iyi-Fe-25Ni-15Cr esekelwe ku-superalloy eqiniswe ngokwengezwa kwe-molybdenum, i-titanium, i-aluminium, i-vanadium ne-trace boron.Ngaphansi kuka-650 ℃, inamandla okukhiqiza aphezulu, amandla ahlala isikhathi eside futhi anyakazayo, i-plasticity enhle yokucubungula nokusebenza okwanelisayo kokushisela. ilungele ukwakhiwa kwezinjini ezinokushisa okuphezulu ezithwala izingxenye ze-aero-injini ezisebenza ngaphansi kuka-650 ℃ isikhathi eside, njenge-turbine disc, i-press disc, i-rotor blade ne-fastener, njll. njengamapuleti, ama-forging, amapuleti, izinduku, izintambo kanye nezingxenye ze-annular.
