347 Urupapuro rwicyuma, Coil na Bar - AMS 5512, 5646
347 ibyuma bidafite ingese ni columbium / tantalum ituje ya austenitis chromium-nikel ibyuma bitagira umwanda. Ibi bikoresho bihamye kurwanya chromium karbide hiyongereyeho columbium na tantalum. Kubera ko ibyo bintu bifitanye isano ya karubone kuruta chromium, karbide ya columbium-tantalum igwa mu ngano aho gushinga imipaka. 347 igomba gutekerezwa kubisabwa bisaba gushyuha rimwe na rimwe hagati ya 800ºF (427ºC) na 1650ºF (899ºC) cyangwa gusudira mu bihe bibuza anneal nyuma yo gusudira. 347 ntabwo ari magnetique.
