Description

Hastelloy® X is a nickel-chromium-iron-molybdenum alloy that possesses an exceptional combination of oxidation resistance, formability and high temperature strength. It has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications. Alloy X exhibits good ductility after prolonged exposure at temperatures of 1200, 1400, 1600 °F for 16,000 hours. It has excellent formability and welding characteristics.

Refer to NACE (National Associate of Corrosion Engineers) for recommendations.

Finishes

#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. #2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D. #BA - Bright annealed cold rolled and bright annealed
#CBA - Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled
#2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished - Various grit finish for specific polish finished requirements.

* Not all finishes are available for all alloys - Contact Ulbrich Sales for more information.

Wire Finishes

XC - Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease - Ultra bright finish (for decorative applications) Soap - Soap coating on tempered wire to act as lubricant.

* Contact Ulbrich Wire for custom wire finishes.

Heat Treatment

Hastelloy® X cannot be hardened heat treating.
