Stainless Steel Passivation Solution

PASSIVE 8 restores the chromic oxide surface film on stainless steel, rendering it inert and restoring it to ‘food-grade’ status. PASSIVE 8 is a concentrated nitric acid solution that is applied to freshly cleaned stainless steel vessels by fogging or spraying. After the recommended contact time and rinsing, the metal is ready for use. PASSIVE 8 can be used on all grades of AlSl 300 Stainless Steels, including 304, 304L, 316, 316L, 316T, and 321.
