Overview

INCONEL® alloy 603XL (patent applied for) is a Ni-Cr alloy with the addition of silicon, molybdenum and rare earth elements. The outstanding characteristics of INCONEL alloy 603XL are its resistance to high temperature oxidation and nitridation. The alloy has high mechanical strength and is readily formed, machined and welded.

The unique combination of high temperature properties make the alloy suitable for many thermal processing applications such as furnace muffles, fixtures, radiant tubes, strand annealing tubes, furnace mesh belts and refractory anchors.

The excellent resistance to oxide spalling make INCONEL alloy 603XL an excellent choice for applications where oxide contamination can not be tolerated such as the electronics, glass and ceramics / tableware industries. Its excellent resistance to nitridation can provide a longer service life in high temperature nitrogen based atmospheres, such as in furnace mesh belts utilized in the powder metal sintering industry and other thermal processing applications.

Oxidation Resistance

INCONEL alloy 603XL has excellent oxidation resistance to 1250°C (2282°F) with the alloying additions promoting excellent oxide scale adherence and reducing the rate of mass change in both static and cyclic conditions.

Nitridation Resistance

INCONEL alloy 603XL has excellent resistance to nitridation up to 1180°C (2150°F). Lacking the alloying elements such as Nb or Al that form internal nitrides INCONEL alloy 603XL exhibits freedom from microstructural degradation in nitrogen based atmospheres.
