Cadmium olive drab chromate
The same protection as yellow chromate, in the olive drab finish required by military and aerospace specifications.
Olive drab meets specifications that call for this finish for identification or as a camouflage requirement. The electrolytic base is the same as the yellow, with the chromate swapped.
The designation is the same as the yellow — ASTM B766 class 12 type II — and so is the performance: 1,000 hours of salt spray to red rust, with an ASTM B117 report from an ISO/IEC 17025 accredited laboratory. What changes is the chromate.

The applications that come here.
Identification requirement
A specification that tells the finish by its color, to separate a lot or system at goods-in.
Camouflage requirement
Component where a dark, matte finish is part of the design.
Same class as the yellow
Where the standard calls for ASTM B766 class 12 type II and color is the only open variable — performance does not change.
What specifiers usually ask.
Does olive drab protect less than yellow?
No. The designation is the same — ASTM B766 class 12 type II — and so is the performance: 1,000 hours of salt spray to red rust, with an ASTM B117 report from an ISO/IEC 17025 accredited laboratory. What changes is the chromate.
When is olive drab specified instead of yellow?
When the requirement is visual identification or camouflage, not protection. The electrolytic base is identical; the choice lies in the conversion finish.
