Incoloy 330

PRODUCT DESCRIPTION

Incoloy 330 (UNS N08330; W. Nr. 1.4886) is an austenitic alloy with good high-temperature strength and corrosion resistance. It has a solid solution composition and is not hardenable by heat treatment. Its high nickel and chromium provide good resistance to oxidation and carburization. Its oxidation resistance is enhanced by the silicon content.
Incoloy 330 strength and oxidation resistance at elevated temperatures make it a useful material for industrial heating furnaces; for muffles, retorts, conveyor systems, baskets and boxes, and various fixture
Incoloy 330 is an alloy comprising of nickel-iron-chromium with silicon as an additive. Using silicon as an additive gives the alloy enhanced oxidation resistance. This alloy exhibits good strength at high temperatures and good resistance to oxidation and reduction environments.
Incoloy 330 The microstructure of the alloy maintains its stability even after being exposed to high temperatures for long durations. The standard forms in which the alloy is available are forging stock, pipe, tube, round bar, flat bar, hexagon and wire.
