I-SUS347 (347/S34700/0Cr18Ni11Nb) iwuhlobo lwensimbi ene-austenitic stainless steel ukumelana kahle nokugqwala kwekristalu.
Inokumelana nokugqwala okuhle ku-asidi, i-alkali noketshezi lukasawoti, futhi inokumelana okuhle ne-oxidation kanye nokushisela emoyeni ngaphansi kuka-800 °C.Insimbi engagqwali engu-347 inokwephulwa kwengcindezi yokushisa okuphezulu kakhulu (Ukuqhekeka Kwengcindezi) kanye nokushisa okuphezulu kokumelana nengcindezi izakhiwo zemishini zingcono kunensimbi engagqwali engama-304.Isetshenziswa kabanzi kwezokundiza, ukukhiqiza amandla, ikhemistri, i-petrochemical, ukudla, iphepha neminye imikhakha.
