Rod cobalt alloy 35N™

platefor the aerospace industry

ATI 35N is a multi-phase nickel-cobalt-chromium-molybdenum alloy that can be heat treated to achieve very high strength, while maintaining excellent low temperature toughness, ductility and corrosion resistance. To achieve tensile strength levels of 260 to 300 ksi (1793 to 2069 MPa), the alloy is cold worked and precipitation hardened. ATI 35N alloy has excellent corrosion resistance in various chloride environments, as well as mineral acids (nitric, hydrochloric and sulfuric). Additionally, the alloy has exceptional resistance to crevice corrosion in seawater and sulfide stress cracking in severe downhole environments. Typical applications are found in medical, aerospace, oil & gas, and chemical processing. A maximum service temperature of 750F (400°C) is suggested.

AMS 5845 - VIM-VAR Bar, Solution heat treated at 1900-1925°F 1040-1050°C) for 4 to 8 hours, Work Hardened plus Aged at 1000-1200°F (538-649°C) for 4 hours. NACE MR0175 / ISO 15156 – Petroleum and Natural Gas Industries ASTM F-562 - Surgical Implant Applications BS 7252-6 Surgical Implant Applications ISO 5832-6 Surgical Implant Applications HEAT TREATING After solution annealing at 1900-2000F (1038-1093°C) followed by working hardening, ATI 35N alloy can be precipitation hardened in the temperature range of 800-1500°F (427-816°C). For higher strength mechanical properties, cold worked ATI 35N alloy can be aged at 1000-1050°F (538-566°C) for 4 hours, followed by air cooling.
