I-alloy 28 yintsimbi exutywe kakhulu ye-austenitic enikezela ukuxhathisa kwiindidi zeendaba ezibolileyo.Ngenxa yeziqulatho zayo ze-chromium kunye ne-molybdenum, i-alloy inikezela ukuxhathisa kuzo zombini i-oxidizing kunye nokunciphisa i-acids kunye neetyuwa.Ubukho bobhedu kwandisa ukuchasana kwayo ne-asidi ye-sulfuric.I-alloy isetyenziswa kushishino lwemichiza kunye ne-petrochemical processing.Iityhubhu zealloyi zisetyenzwa ukuya kutsho kumanqanaba aphezulu omelela kwinkonzo yomngxuma kumngxuma ophakathi kwimithombo yerhasi emuncu.
