I-alloy 28 iyinsimbi engagqwali ene-alloyed ye-austenitic enikeza ukumelana nezinhlobo zemidiya ezonakalisayo.Ngenxa yokuqukethwe kwayo kwe-chromium ne-molybdenum, i-alloy inikeza ukumelana nakho kokubili oxidizing nokunciphisa ama-acids nosawoti.Ukuba khona kwethusi kwandisa ukumelana kwayo ne-sulfuric acid.Ingxubevange isetshenziswa embonini yamakhemikhali kanye ne-petrochemical processing.Amashubhu engxubevange asetshenziswa ukubanda aze afike emazingeni aphezulu amandla ensizakalo yokukhipha amanzi emithonjeni yegesi emuncu egqwalile.
