A286 (ASTM A638) ni superalloy yicyuma gikomeza imbaraga nyinshi hamwe no kurwanya okiside igera kuri $ 700 ^ ∘C $. Kugumana impeta muri turbine, iruta ibyuma bitagira umwanda kuko idatakaza 'ubushyuhe bwayo' mubushyuhe bwo gukora. Ibikoresho birakomeye kugirango imvura igere kuri MPa 700-1000. Coefficente yo kwagura ubushyuhe nayo ihuzwa cyane na nikel nyinshi ishingiye kuri nikel ivanze, bigabanya ibyago byimpeta gutakaza imbaraga zayo kubera kwaguka gutandukanye kwinshi. Gutunganya bikubiyemo igisubizo kivura $ 980 ^ ∘C $ gikurikirwa no gusaza $ 720 ^ ∘C $ amasaha 16 kugirango ugabanye icyiciro cya $ \ gamma '.
