Inconel 600 Alloy Round Bar (Ni-Cr-Fe Alloy)
Engineered for aerospace, chemical processing, and nuclear applications demanding exceptional corrosion resistance and thermal stability, Inconel 600 alloy round bar combines a nickel-chromium-iron matrix (Ni-72%, Cr-15.5%, Fe-8%) to deliver superior resistance to oxidation, carburization, and chloride stress corrosion cracking (Cl-SCC) up to 1,100°C (2,012°F). Certified to AMS 5666, ASTM B166, and ASME SB166, this alloy outperforms stainless steel 310 and Incoloy 800 in aggressive environments, offering 2x the lifespan in acidic or high-temperature oxidizing conditions.
