Alloy Steel, Chrome-Moly Steel, Tool Steel, Nitralloy, Hastelloy, Nickel Alloy's, Tool Steels (D2, H13, & CPM 9V) Stainless Steels, High Temperature Alloys and many others. Hardening on screw flights may be accomplished by flame hardening or hard facing such as Stellites or Colmonoys. Corrosion protection may be provided by Ion Nitriding, Nitriding, Chrome or Nickel Plating, or other Carbide Coatings to suit any application.

 

Standard flight hard facing materials include Stellite (#6,12), Colmonoy (#56,83) and corrosion coatings including Standard Hard Chrome, Triple Chrome and Nickel Plating.  (Standard Ion-Nitriding and Flame Hardening are also available.
