KORTECK Cormex-24 Special Plating- Electroless  nickel with silicon or boron particles. Cormex-24tm, double and triple industrial hard chrome plating available to eliminate all porosity. High polished and buffed surfaces as required.

Special O.D. Hardfacing- Example: Flitech 300 for extreme abrasive applications and FT/Mo-42 molybdemum where lubricity is required. Specialized hardfacing  for elevated temperatures, etc.

Mixing Sections- All types rebuilt, manufactured or retrofitted on existing screws..

Special Root Coatings, Weldments and Treatments- Heat treating, nitriding, stelite and Colmonoy Ceramic wearsurfacing. Kortung Nitratech and Diamond Flite.

Flights Added- Have dead area where material is hanging up and burning or degrading? Flights extended through this area, correcting the problem.

Pressure Tests- Screw pressure tested for clear cooling holes, root cracks, and proper tip and “O” ring fit.

Crammer Screws- Manufactured or rebuilt. Two piece sectioned and single.

Partial Flight Rebuilding- Have only certain area where flights wear and don’t want to pay for entire rebuilding cost? No problem; we’re out to save you money whenever possible. Two different hardfacing can be applied to the same screw, maximizing flight protection where necessary.

Hardfacing Thickness Increased- For extreme abrasive wear where units can still run with notable flight O.D. loss and where normal screws are unusable because of accelerating flight abase material wear.

Geometrical Profiling - for Feed screws. Root rebuilding, compression changes , and Korgardtm protective coatings for worn root diameters.
