The aim of this study was to study the relationship between metallic elements migrated from AISI304 and AISI321stainless steel grades into simulant solutions (3%, 6% and 9% acetic acid in double-distilled water) at 22, 28 and 34°C by statistical methods. The migration of Cr, Mn, Fe and Ni ions from AISI304 stainless steel grade, Ti, Cr, Mn, Fe and Ni from AISI321stainless steel grade respectively was studied. The correlation between variables - ions which migrate from stainless steel samples - based on Pearson correlation matrix was analyzed to fulfill its purpose and Principal Component Analysis (PCA) statistical method was used to explain the similarities or differences between them.The results indicate on one hand a strong corelation between Cr, Fe and Mn ions migrated from AISI304 stainless steel samples and on the other hand a strong one between Mn and Fe ions migrated from AISI321 stainless steel samples into simulant solutions. |
