347 Xaashiyaha Biraha Aan-Aabaha ahayn, Gariiradda iyo Bar - AMS 5512, 5646
347 birta aan dahsoon waa kolumbium/tantalum degenaansho austenitic chromium-nickel steel. Maaddadan waxaa lagu dejiyaa ka-hortagga samaynta karbohaydraytyada chromium iyadoo lagu darayo kolumbium iyo tantalum. Maadaama walxahan ay leeyihiin xidhiidh ka xoog badan kaarboonka marka loo eego chromium, kolumbium-tantalum karbides waxay ku da'ayaan gudaha badarka halkii ay ka samayn lahaayeen xuduudaha badarka. 347 waa in loo tixgeliyo codsiyada u baahan kuleyl dhexdhexaad ah inta u dhaxaysa 800ºF (427ºC) iyo 1650ºF (899ºC) ama alxanka marka la eego xaaladaha ka hortagaya soo laabashada alxanka kadib. 347 waa non-magnetic.
