Ingxubevange 20yi-insimbi engagqwali ye-austeniticyakhelwe izicelo ezibandakanyai-sulfuric acid. Ukumelana nokugqwala kwayo kuthola okunye ukusetshenziswa ku-amakhemikhali,i-petrochemical,ukukhiqiza amandla, futhiamapulasitikiizimboni. Ingxubevange 20 ukumelanaumgodifuthii-chloride ionukugqwala, kangcono kune304insimbi engagqwali futhi ihambisana nayo316Linsimbi engagqwali. Okuqukethwe kwayo kwethusi kuyivikela ku-sulfuric acid. I-alloy 20 ivame ukukhethwa ukuxazululai-stress corrosion crackingizinkinga, ezingase zenzeke nge-316L engenasici. Ingxubevange yegama elifanayo negama elithi “Cb-3″ libonisaColumbiumuzinzile.
