Even 5 microns of zinc ( ASTM B633 [affil. link to spec at Techstreet] "Mild" service condition) will deliver 96 hours to white rust if the chromate conversion coating is done well. But selecting the zinc plating thickness based on salt spray hours may be wrong thinking.

For 600 Hours to RED rust you would look at a system that will fail to white rust in 200 to 300 Hours applied over at least 35 to 40 microns of regular zinc plate from an alkaline zinc bath. This column does not permit use of proprietary information.

Our Class 3 & Class 4 plated fasteners also tested in ASTM B117-03 Salt Spray Test. The salt spray test result indicates that there is no significant sign of Red rust at 1,000 hours. This is due to the nature of the sealers rather than the base metal protection. Please note that Salt Spray Testbears no reflection to real world performance.

Additionally, compared to hot-dip galvanizing, mechanical plating does not require threads to be chased after plating. At Chem-Plate Industries, we offer a wide range of mechanical plating processes including Standard Zinc Plating and Galvanizing, Silver Plating, Zinc Aluminum coatings, Tin Coatings, and our CP 2000 process which is a quad metal coating with salt spray …

shall show no surface corrosion products after 96 hours (20%) salt spray exposure. Parts with hardness greater than RC-40 shall be stress- relieved before cleaning and plating. Parts subject to flexure (springs) over RC-40 hardness shall be given a 375F post-bake. Excellent for plating

If you wanted some chromated zinc-plated parts to pass 96 hours in salt spray to white rust, the exact same part is expected to reach anywhere between 61 and 131 hours if placed in two different chambers. So, unless your part averages 150 hours in salt spray, on average, half your parts will fail and half your parts will get to 96 hours and above.
