Passivation of Stainless Steel

QQ-P-35 Type II, VI, and VII, Mil-S-5002, ASTM A967
Passivation of Stainless Steel is a process which treats the surface of the metal to impede corrosion. The process has two primary functions. First to remove any iron on the surface of the part. Second to promote the growth of nickel and chrome oxides which give stainless steel its excellant corrosion resistant surfaces.
Passivation is used in many industries Also a broad sprectrum of nickel alloys can be passivated. These include 300 series, 400 series, inconel, hastelloy, 17-4, 13-8 and A286. It should be noted that if a stainless steel is improperly heat treated there is a risk of etching the parts in the passivation process - this mostly a concern for 400 series alloys.
