Basic Introduction of Inconel Alloy 601
INCONEL nickel-chromium-iron alloy 601 (UNS N06601/W.Nr. 2.4851) is a general-purpose engineering material for applications that require resistance to heat and corrosion. An outstanding characteristic of INCONEL alloy 601 is its resistance to hightemperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined and welded. The limiting chemical composition of INCONEL alloy 601 is listed in Table 1. The composition is a facecentered-cubic solid solution with a high degree of metallurgical stability. The alloy’s nickel base, in conjunction with substantial chromium content, provides resistance to many corrosive media and hightemperature environments. Oxidation resistance is further enhanced by the aluminum content.
