347 is niobium-ine autenitic simbi isimbi, nepo 347h iri yakakwira kabhoni kabhoni. Panyaya yekuumbwa,347Inogona kuoneka seiyo lloy inotorwa kubva pakuwedzera niobium kusvika pachigadziko che304 simbi isina tsvina. Niobium chinhu chisingawanzo chinhu chinogadziriswa icho chinoshanda nenzira yakafanana kune Titanium. Kana zvakawedzerwa kune alloy, inogona kunatsa zviyo zviyo, ramba kuwirirana Corroson, uye kusimudzira zera.
