  • Wroughtable, chromium-bearing, cobalt-based alloys with improved resistance to galling and chloride-induced crevice attack
    Patent number: 12577640
    Abstract: A chromium-bearing, cobalt-based alloys amenable to wrought processing has improved resistance to both chloride-induced crevice corrosion and galling. The alloy contains up to 3.545 wt. % nickel, 0.242 to 0.298 wt. % nitrogen, and may contain 22.0 to 30.0 wt. % chromium, 3.0 to 10.0 wt. % molybdenum, up to 5.0 wt. % tungsten, up to 7 wt. % iron, 0.5 to 2.0 wt. % manganese, 0.5 to 2.0 wt. % silicon, 0.02 to 0.11 wt. % carbon, 0.005 to 0.205 wt. % aluminum, and the balance is cobalt plus impurities.
