Special Metals INCOLOY® Alloy 330
Categories:	Metal; Superalloy; Iron Base
Material Notes:	A nickel-iron-chromium alloy with an addition of silicon for enhanced oxidation resistance. It has good strength at high temperatures and excellent resistance to carburizing and oxidizing atmospheres. The alloy's austenitic microstructure remains stable during long-time exposure to high temperature. Used in industrial heating for furnace muffles, retorts, and conveyor systems and for heat-treating baskets and fixtures. Standard product forms are round, flats, forging stock, plate, sheet, strip, and wire. Data provided by the manufacturer, Special Metals.
Key Words:	SAE AMS 5592, 5716; SAE J405, J412, UNS N08330; ASTM B 511, B 512, B 535, B 536, B 546, B 710; ASME SB-511, SB-536, SB-710, Boiler Code Sections I, VIII, IX
