| Electroless
Nickel Plating
Similar
to stainless steel in color. Plates uniformly in recesses
and cavities (does not build up on edges). Corrosion
resistance is good for coatings over .001” thickness.
Electroless nickel is used
extensively in salvage of mismachined parts. Also, for
inside dimensions and irregular shapes (where assembly
tolerances need uniformity provided by electroless process).
This spec does not specify the phosphorous content in
the EN deposit provided it passes 100 hours salt spray
test at 1.0 mil for AL and 1.5 mil for steel. Please
note: This specification has been re-instated. Rein.
