Salt spray life of zinc plating with chromate



2002

Dear sir,

Please provide the salt spray resistance (ASTM ASTM B117 [affil. link to spec at Techstreet] ) achievable with various chromate passivation on zinc plated components with respect to white rust formation. In our practical tests we have achieved up to 250 hours white rust salt spray life for green and yellow passivation.

Thank you,

You're doing fine, Siva. Olive drab should do 150 hours, yellow 96 hours.
