CADMIUM PLUS CLEAR CHROMATE ( CI )
Applicable Industry Spec: ASTM B766, CLASS 5, TYPE III
QQ-P 416 Class 3 Type I & clear Chromate

• The parts shall be capable of passing a 12 hour salt spray test to white corrosion and a minimum of a 100 hour salt spray test to red rust per ASTM B117.
• Typically, cadmium plus clear chromate offered by PEM is .0002″ minimum of cadmium applied to all significant surfaces. Significant surfaces exclude such features as threads, holes, deep recesses and bases of angles.
• A clear chromate conversion coating is applied after cadmium plating.
• Steel parts requiring embrittlement relief after plating are baked according to industry standards.

• The parts shall be capable of passing a 12 hour salt spray test to white corrosion and a minimum of a 100 hour salt spray test to red rust per ASTM B117.
• Typically, cadmium plus metric blue chromate offered by PEM is .0002″ minimum of cadmium applied to all significant surfaces. Significant surfaces exclude such features as threads, holes, deep recesses and bases of angles.
• A clear chromate conversion coating with blue dye is applied after cadmium plating.
• Steel parts requiring embrittlement relief after plating are baked according to industry standards.
