UltraOx® "P"

Advanced Heat Treat's UltraOx® "P" treatment gives all the benefits of UltraOx®, with masking capabilities! It can further improve the corrosion resistance properties attained by the nitriding cycle. This is a passivation process in which oxygen bonds with ferrous alloys at a low processing temperature.

Benefits of UltraOx® "P"

  • Improves corrosion resistance
  • Selective hardening can be achieved through masking capabilities
  • Reduces adhesive wear & increases fatigue strength
  • Outperforms and outlasts chromium and nickel plating, as well as powder coating
  • No surface pitting, flaking or hydrogen embrittlement
  • Produces aesthetic, smooth black finish
  • Easily surpasses salt spray test of 240 hours per ASTM B117
  • Achieves a minimum surface hardness of 55+ HRC (or equivalent)
  • Can be used on long parts
  • 100% part coverage
  • Produces thick compound zone (white layer) - up to 0.0015"+

In a salt spray test which was run by a third party metallurgical lab and conducted using ASTM B117 guidelines, the corrosion resistance looked good. It went 432 hours before any rust trails developed."
