Ingxubevange 20yiintsimbi ye-austeniticiphuhliselwe izicelo ezibandakanyaiasidi yesulfuric. Ukunganyangeki kwayo kwe-corrosion iphinda ifumane ezinye izinto ezisetyenziswayo kwiikhemikhali,petrochemical,ukuveliswa kwamandla, kwayeiiplastikiamashishini. I-alloy 20 iyaxhathisaukugqobhozakwayeikloridi ionumhlwa, ngcono kuno304insimbi engenasici kwaye ihambelana nayo316Lyenziwe ngentsimbi eshayinayo. Umxholo wayo wobhedu ukhusela kwi-asidi ye-sulfuric. I-alloy 20 ihlala ikhethwa ukusombululaukuqhekeka kwe-corrosion yoxinzeleloiingxaki, ezinokuthi zenzeke nge-316L engenasici. Ingxubevange yegama elifanayo negama elithi "Cb-3" libonisaColumbiumuzinzisiwe.
