UltraOx® is Advanced Heat Treat Corp.'s heat treat process that provides an extra layer of corrosion and wear protection with a sleek black finish. It has been widely used to replace chrome plating, nickel plating, QPQ (quench-polish-quench) and melonite/salt bath.

I am pushing for all prints going forward to call out UltraOx®….it looks so much better than our current salt bath!

I had the sample bar that you sent me salt spray tested and the corrosion resistance looked good. It went 432 hours before any rust trails developed.
