What can Expanite be used for?


ALL stainless steel alloys:

Increase WEAR, GALLING or CORROSION resistance of stainless steel

AUSTENITIC and DUPLEX stainless steel:

  • Replace known processes such as Kolsterising® from Bodycote and NV Pionite® Air Water Inc. Typically outcome; faster lead-time, cost reduction and improved corrosion resistance
  • Replace hard-chrome plating/coatings. Typically outcome; replace the coatings with diffusion – no issues with spalling and inhomogenous layers
  • Replace plasma nitriding. Typically outcome; improved corrosion resistance

FERRITIC and MARTENSITIC stainless steel:

  • Replace conventional heat treatment/vacuum hardening with ExpaniteHigh-T or SuperExpanite®.Typically outcome; significant increase in wear and corrosion resistance
