Abstract | : | In order to evaluate the effect of relative humidity (RH) and kind of chlorides on pitting in atmosphere of SUS304 and SUS430 stainless steel, pitting test were carried out in RH controlled environment by surface of specimens deposited sea water or NaCl and MgCl_2 solutions for 6 months.
It was concluded that pitting occured at low RH, such as RH 33%, rather than high RH as a whole. Because it became higer concentration of chlorides in low RH under the thin layer of electrolyte. The tendency of occurrence on pitting in case of attached sea water governed by MgCl_2 which is sub element of sea water. |
