Nickel-Cobalt Alloy 556 Bar
Nickel-Cobalt Alloy 556 Bar (UNS R30556) is a solid-solution-strengthened alloy designed for outstanding resistance to oxidation and sulfidation at elevated temperatures. This alloy combines the strength of cobalt and nickel with the corrosion resistance of chromium and molybdenum, making it ideal for high-temperature industrial environments.
