Tšobotsi ea Alloy

SS316L ke austenitic chromium-nickel tšepe e sa jeleng paate e nang le molybdenum le khabone e tlase.

Khanyetso ea Corrosion
Li-acids tse phelang maemong a holimo le mocheso o itekanetseng.
Li-inorganic acid, mohlala, phosphoric le sulfuric acid, maemong a itekanetseng le mocheso.Tšepe e ka boela ea sebelisoa ka sulfuric acid ea concentrations ka holimo ho 90% mocheso o tlase.
Metsoako ea letsoai, mohlala, sulphates, sulfide le sulphites.

Libaka tsa Caustic
Litšepe tsa Austenitic li kotsing ea ho senyeha ha corrosion.Sena se ka etsahala ka mocheso o ka holimo ho 60 ° C (140 ° F) haeba tšepe e le tlas'a khatello ea maikutlo 'me ka nako e ts'oanang e kopana le litharollo tse itseng, haholo-holo tse nang le chloride.Ka hona, maemo a joalo a ts'ebeletso a lokela ho qojoa.Maemo ha limela li koetsoe le tsona li tlameha ho nahanoa, kaha li-condensate tse theoang ka nako eo li ka ba le maemo a lebisang khatellong ea khatello ea maikutlo le ho phunyeha ha likoti.
SS316L e na le khabone e tlase mme ka hona e hanyetsana hantle le ho bola ha intergranular ho feta litšepe tsa mofuta oa SS316.
