601
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.
