Inconel 601 (UNS N06601) Seamless Pipes & Tubes
Alloy 601 (Inconel 601, UNS N06601) is a nickel-chromium alloy with aluminum addition that provides outstanding oxidation resistance to 1250C. The aluminium content forms a tightly adhering oxide scale that resists spalling under thermal cycling conditions.
