ASTM B166 UNS N06600 Nickel Alloy Bright Annealed Bar
ASTM B166 UNS N06600 Nickel Alloy Bright Annealed Bar
ASTM B166 UNS N06600 is a high-strength nickel-chromium alloy bar with good oxidation resistance and excellent resistance to chloride stress corrosion cracking, suitable for high-temperature and corrosive environments such as chemical plants and nuclear power plants. A bright annealed surface refers to a bright, polished surface obtained through a bright annealing process, which improves surface finish and reduces absolute roughness.
What is the maximum operating temperature of Inconel 600?
2000°F
Inconel 600 (AMS 5540) is a nickel-chromium alloy designed for low-temperature and high-temperature environments up to 2000°F (1093°C).
Inconel 600 round bars are a nickel-based alloy with good carburizing properties and excellent high-temperature corrosion resistance. Inconel 600 round bars effectively resist dry chlorine and many other gases at moderately high temperatures. Alloy 600 bars are a nickel-chromium alloy with good high-temperature oxidation resistance and resistance to decomposition cracking under chloride pressure, corrosion from high-cleanliness water, and acid oxidation. Inconel 600 flat bars are also a nickel-chromium-iron alloy with good high-temperature corrosion resistance and resistance to rapid corrosion under chloride ion pressure, corrosion from high-cleanliness water, and combustion corrosion.
The chemical composition of this nickel-based steel alloy is carefully designed to provide excellent resistance to a variety of corrosive environments. Inconel 600 is a standard engineering material with excellent heat and corrosion resistance. Inconel 601 also features high strength, good machinability, excellent metallurgical stability, and high resistance to carburizing. Inconel 600 is hardened and strengthened through cold working processes.
