Nickel 601 Alloy equivalent
Other names for Nickel Alloy 601 (UNS N06601) include Werkstoff Nr. 2.4851, EN 2.4851, NiCr23Fe, and trade names such as Inconel 601, Pyromet 601, and Nicrofer 601. All of these refer to the same nickel-chromium-iron alloy, which conforms to standards such as ASTM B166/B168 (for plates/bars/tubes) and possesses excellent high-temperature strength and oxidation resistance.
What is the composition of 601 alloy?
601 alloy is a nickel alloy, primarily composed of nickel and chromium, and containing small amounts of aluminum, silicon, copper, and manganese.
What is Alloy 601 / INCONEL 601?
Nickel 601 is a nickel-based alloy containing a high percentage of chromium (approximately 25%) and added aluminum, specifically designed to resist high-temperature oxidizing atmospheres during metal and material heat treatment processes. It is one of the most commonly used materials for thermocouple protection tubes and oxygen injection tubes in the metal and glass manufacturing industries.
