Hastelloy is the general name of the commercial grades of nickel-based corrosion-resistant alloys produced by the United States Hastelloy International. Hastelloy alloy is a nickel molybdenum chromium superalloy that has tungsten added into the composition. It is very resistant to pitting corrosion and crevice corrosion. Including nickel-molybdenum-based Hastelloy B-2, Hastelloy C-22, Hastelloy X, Hastelloy C-276 ect.
HT PIPE provide several types of Hastelloy Pipes for the Oil and Gas, Petrochemical and Power Industries.
