347 iyo 347H labaduba waa darajooyin bir aan lahayn austenitic kuwaas oo lagu xasiliyay kolumbium (niobium) waxaana badanaa loo isticmaalaa codsiyada heerkul sare. "H" ee 347H waxay u taagan tahay "kaarboon sare", taas oo muujinaysa inay leedahay kaarboon sare marka loo eego heerka 347 birta aan lahayn.
