Inconel 601 is a nickel-chromium alloy, that is highly resistant to
oxidation through 2200°F. 601 alloy develops a tightly adherent
oxide scale which resists spalling even under severe thermal
cycling. The alloy has good high temperature strength, and retains
its ductility after long service exposure. 601 alloy has good hot
corrosion resistance under oxidizing conditions. 601 alloy is not
suggested for use in strongly reducing, sulfur bearing
environments.
For maximum oxidation resistance, 601 alloy should be welded with
matching composition 601 alloy GTAW wire. The weld fillers
developed for RA 602 CA can also provide a weld which is stronger
and more oxidation resistant than the 601 alloy base metal. 601
alloy is more difficult to machine than 304 stainless steel. Its
machinability rating is 15-21% relative to AISI B1112 steel.
