347 Ishidi Lensimbi Engagqwali, Ikhoyili Nebha - AMS 5512, 5646
347 insimbi engagqwali iyi-columbium/tantalum ezinzile austenitic chromium-nickel insimbi engagqwali. Lokhu okubalulekile kuzinza ngokumelene nokwakheka kwe-chromium carbide ngokungezwa kwe-columbium ne-tantalum. Njengoba lezi zakhi zinokusondelana okunamandla kwekhabhoni kune-chromium, i-columbium-tantalum carbides igxuma phakathi kwezinhlamvu esikhundleni sokwakheka emingceleni yokusanhlamvu. 347 kufanele kucatshangelwe izinhlelo zokusebenza ezidinga ukushisisa kwezikhawu phakathi kuka-800ºF (427ºC) no-1650ºF (899ºC) noma ukushisela ngaphansi kwezimo ezivimbela i-post-weld anneal. I-347 ayiyona i-magnetic.
