Inconel 601 Alloy Coil (Ni-Cr-Fe-Al Alloy)

Engineered for aerospace, industrial furnace, and chemical processing applications demanding extreme oxidation resistance and thermal stability, Inconel 601 alloy coil combines a nickel-chromium-iron-aluminum matrix (Ni-60%, Cr-23%, Fe-14.5%, Al-1.4%) to deliver unmatched resistance to oxidation, carburization, and thermal fatigue up to 1,250°C (2,282°F). Certified to AMS 5713, ASTM B168, and ASME SB168, this alloy outperforms Inconel 600 and 310S stainless steel in high-temperature oxidizing environments, offering 3x the lifespan in cyclic thermal applications.
