Zinc Plated Dipped Dichromate Treatment

[FrancoisY]

Hello all,

It seems like there are quite the issue now and days with dichromate. Does anyone know what has replaced it in ASTM B633 standard? i do not have access to it. What has replaced it or equivalent that can pass Type VI with 120HR minimum Salt Spray pass?

There are inorganic zinc/aluminum flake products that are far superior to zinc chromate for corrosion resistance. An example trade name is Dacromet.
