Materialdesignation: Hastelloy C22 Hastelloy

US grade: UNS N06022

I. Overview of Hastelloy C22(N06022):

Hastelloy C22（N06022）is nickel-based superalloy which contain Nickel,molybdenum, cobalt, tungsten and other elements and its nickel content is about60%.

II. Chemical composition: SeeTable 1-1.

Table1-1 %

III. Physical properties: Density:8.9 g / cm3, melting point: 1325-1370 ℃

IV. Features:

Hastelloy C22 (N06022) is a versatilenickel-chromium-molybdenum-tungsten alloy that has better overall corrosionresistance than other existing nickel-chromium-molybdenum alloys. The alloy hasgood resistance to pitting, crevice corrosion and stress. Corrosion andcracking ability. It has excellent resistance to oxidizing aqueous media,including wet chlorine, nitric acid or mixed acids containing oxidizing acidscontaining chloride ions.

V. Application areas:

Acetic acid / acetic anhydride, acid leaching,cellophane manufacturing, chlorination system, complex mixed acid, galvanizedrollers, expansion bellows, flue gas cleaner system, geothermal well, hydrogenfluoride furnace cleaner, incinerator cleaner system, nuclear fuelregeneration, pesticide production, phosphoric acid production, picklingsystems, plate heat exchangers, selective filtration systems, sulfur dioxidecooling towers, sulfonation systems, tube heat exchangers, overlay weldingvalves.

VI. Specifications and   Ex-factory status:

1. Classification: Huacheng Jinyan can supplyin form of C22（N06022）seamless pipes, steel plates, roundsteel, forgings, flanges, rings, welded pipes, steel strips, wire andsupporting welding materials.

2. Ex-factory status: Seamless Tube: solidsolution + acid white, length can be fixed; Plate: solid solution, pickling,trimming; Welded Tube: solid solution acid white + RT% flaw detection; Forging:annealing + turning; the bar is delivered in the state of forging, surfacepolishing or lapping; the strip is delivered after cold rolling, solid solutionsoftening, and descaling; the wire is solid-dissolved and pickled in a disc orstraight strip, solid solution straight polished.
