A yanayin zafi na cryogenic (misali, $-320 ^{\circ}F$), 302/304 bakin karfe na iya jurewa wani juzu'i na martensitic canji, wanda zai iya ƙara maganadisu da brittleness. A286 (AMS 5525) wani babban ƙarfe ne na ƙarfe wanda ya kasance cikakke austenitic da ductile a yanayin zafi na cryogenic. A286 yana ba da ƙarfin yawan amfanin ƙasa fiye da 300-jerin bakin ruwa ta hanyar hazo mai ƙarfi, yana sa ya dace da bawuloli masu ɗaukar nauyi na cryogenic. Yayin da 302 ya fi tsada-tsari kuma gama gari don amfanin masana'antu na gabaɗaya, A286 shine ma'aunin fasaha don tsarin LH2 (Liquid Hydrogen) ko LNG (Liquefied Natural Gas) inda tauri da kaddarorin magnetic ke da mahimmanci.
