Isebenzisa i-SS yezikhonkwane kunye neekhonkco zangaphandle, kunye neplastiki ekhethekileyo yobunjineli (i-matte emhlophe, i-POM okanye i-PA6) kwiikhonkco zangaphakathi, ukwenzela ukuxhathisa okungcono kwe-corrosion kunochungechunge oluqhelekileyo. Nangona kunjalo, cetyiswa xa ukhetha ukuba owona mthwalo uphezulu uvumelekileyo yi-60% yochungechunge oluqhelekileyo lwetsheyini.
