The Passivation process is a method of removing metal oxides, heat treat scale, and other foreign materials from stainless steel, leaving the surface chemically clean and prepared for further processing. Passivation restores the original corrosion resistant surface by forming a thin, transparent oxide film on the part. Parts that are to be soldered or brazed should be passivated before, but not after, these operations.
We offer the following: Passivation CRS Types II, VI, VII and VIII to QQ-P-35 and Passivation CRS class F, H and I to ASTM A380, and Passivation CRS Nitric types 1, 2 and 4 per specification ASTM A967.
