Incoloy 330 Round Bars

Product Details

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, conveyor systems and heat-treating baskets and fixtures.

STANDARD PRODUCT FORMS
Tube, sheet, strip, plate, round bar, forging stock,
hexagon, wire, and wire rod.
