About Alloy
NIMONIC alloys consist of nickel and chromium as the principal components. High-temperature low creep and good corrosion resistance are some of the characteristics of these alloys. Additives like carbon, titanium and aluminium enhances the toughness of the alloy. Some of the NIMONIC alloys available commercially are NIMONIC 75, NIMONIC 80A, 81, 86 and NIMONIC PE11 and 16.
NIMONIC alloy 86 is an alloy of nickel-chromium-molybdenum. It exhibits good weldability, workability, ductility and creep. It also exhibits excellent oxidation resistance at high temperatures. The additive for this alloy is cerium, a rare-earth. This alloy is available in the form of sheet, strip, round, extruded section and wire.
Alloy 86 has good formability and weldability with exceptional resistance to oxidation and scaling to 1050°C (1920°F). Alloy 86 is quite rare due to its "Cerium" addition although it is widely used in afterburners and heat treating furnaces.
