347 Ishiti leNsimbi elingenaStainless, iKhoyili kunye neBar – AMS 5512, 5646

I-347 insimbi engenasici yi-columbium / tantalum ezinzile i-austenitic chromium-nickel yensimbi engenasici. Esi sixhobo sizinzile ngokuchasene nokwakheka kwe-chromium carbide ngokongezwa kwe-columbium kunye ne-tantalum. Kuba ezi zinto zinobudlelwane obunamandla bekhabhoni kune-chromium, i-columbium-tantalum carbides idlula ngaphakathi kweenkozo endaweni yokubumba kwimida yengqolowa. I-347 kufuneka ithathelwe ingqalelo kwizicelo ezifuna ukufudumeza okwethutyana phakathi kwe-800ºF (427ºC) kunye ne-1650ºF (899ºC) okanye i-welding phantsi kweemeko ezithintela i-post-weld anneal. I-347 ayinamagnetic.
