MP35N alloy steel bar is a nickel, chromium, cobalt alloy. MP 35N is non-magnetic and possesses an ultra-high tensile strength, and provides for good ductility. MP35N has a maximum 750 degree F temperature capability. In addition, it has excellent corrosion resistance as well to chloride solutions, mineral acids, and in hydrogen sulfides. The ability of MP35N to resist stress-corrosion and crevice corrosion often leads to to its selection as a fastener material, although its uses also include petrochemical equipment, racing engines and submersibles. This alloy is typically work-strengthened and aged to obtain strength levels of 260 to 300 ksi.
