Corrosion Resistance:Zoo heev; Cov ntsiab lus nickel siab ua rau muaj kev tiv thaiv muaj zog, tiv taus xeb thiab xeb, txawm tias nyob hauv cov chaw ntub dej / acidic / chlorinated.

Kev txwv:Cov nqi pib siab dua; qee qib (xws li 304) tseem yuav muaj kev txwv rau cov tshuaj chloride hnyav heev.

Qhov zoo tshaj plaws rau:Kev ua zaub mov, kev kho mob, marine, chemical industries, coj mus muag chav ua noj, thiab chaw ntub dej.
