Inconel 617 Alloy Round Bar (Ni-Cr-Co-Mo Alloy)
Engineered for aerospace, energy, and nuclear applications demanding extreme thermal stability and creep resistance, Inconel 617 alloy round bar combines a nickel-chromium-cobalt-molybdenum matrix (Ni-52%, Cr-22%, Co-12.5%, Mo-9%) to deliver exceptional oxidation resistance, carburization resistance, and mechanical strength up to 1,100°C (2,012°F). Certified to AMS 5887, ASTM B166, and ASME SB166, this alloy outperforms Inconel 625 and Haynes 230 in high-stress, high-temperature environments, offering 3x the creep rupture life of 310S stainless steel at 950°C (1,742°F).
