Hastelloy Castings & Forgings
Hastelloy Ni-Mo and Ni-Cr-Mo alloys offer strong resistance to oxidizing and reducing acids, mixed chemistries and severe pitting environments. Monmet supplies Hastelloy in cast and wrought form.
Quick answer
Hastelloy Ni-Mo and Ni-Cr-Mo alloys resist oxidizing and reducing acids, mixed chemistries and severe pitting in chemical reactors, FGD scrubbers and sour-service valves. Grade choice depends on whether the process chemistry is oxidizing or reducing. Monmet supplies Hastelloy castings and forgings, solution-annealed and water-quenched to preserve corrosion resistance.
Grade Selection
Grades are selected for the specific corrosive environment — wet chlorine and FGD scrubbers, oxidizing acids, or hydrochloric and sulfuric acid service. We will help match a grade to your application.
Castings
Hastelloy castings are solution-annealed and water-quenched to retain corrosion resistance.
Applications
FGD scrubber internals, pulp-bleach equipment, chemical reactors, evaporators, sour-service valves and tubular components.
