Alloy 20iri anaustenitic simbi isina tsvinayakagadzirirwa zvikumbiro zvinosanganisirasulfuric acid. Kuramba kwayo kwekuora kunowanawo zvimwe zvinoshandiswa mumakemikari,petrochemical,kugadzirwa kwemagetsi,uyemapurasitikimaindasitiri. Alloy 20 inopikisapittinguyechloride ionngura, nani pane304simbi isina tsvina uye inoenderana ne316Lsimbi isina ngura. Yayo mhangura inodzivirira kubva kune sulfuric acid. Alloy 20 inowanzosarudzwa kugadzirisastress corrosion crackingmatambudziko, anogona kuitika ne316L isina tsvina. Alloy yezita rimwe chete rine zita rekuti "Cb-3" rinoratidzacolumbiumstabilized.
