A-286 (irin baƙin ƙarfe-nickel-chromium tushen superalloy, ASTM A638) yana da daraja don ikonsa na kiyaye ƙarfin ƙarfi da juriya na iskar shaka daga yanayin yanayin cryogenic ($-423 ^{\circ}F $) har zuwa $1300 ^{\circ}F$. Ba kamar wasu bakin karfe waɗanda suka zama gaggautsa a yanayin zafi na cryogenic, A-286 yana kula da ductility da taurinsa. A cikin maɓuɓɓugan ruwan raƙuman ruwa, wannan ya sa ya dace da kayan aikin ruwa na nitrogen ko iskar oxygen. Matsakaicin haɓakar haɓakar yanayin zafi shima yana da ɗan ƙaramin ƙarfi, wanda ke taimakawa ci gaba da ɗora kayan aikin bazara a lokacin matsanancin hawan zafi na gama gari a cikin abubuwan injin roka. Gudanarwa ya ƙunshi mataki na ƙarfafa shekaru (yawanci $ 1325 ^{\circ}F$ na awanni 16) don haɓaka matakin gamma-prime $
