MP35N STA Cold Drawn is a cobalt-nickel-chromium-molybdenum superalloy in solution-treated and aged condition with cold-drawing, used primarily in high-temperature aerospace fasteners and springs requiring exceptional strength retention to 600°C and excellent corrosion resistance in oxidizing and seawater environments. The cold-drawn condition provides increased yield and tensile strength with controlled ductility, making it suitable for applications demanding both mechanical performance and fatigue resistance at elevated temperatures.
