Inconel 601 (UNS N06601) seamless and welded pipes are extensively utilized in thermal processing, industrial furnaces, radiant tubes, and petrochemical equipment. Due to its balanced nickel-chromium composition supplemented with aluminum, the alloy forms a tightly adherent oxide scale that resists spalling even under severe thermal cycling conditions.
