MP35N® Alloy Steel Bar - AMS 5844
MP35N® alloy steel bar is a nickel, chromium, and cobalt alloy. This grade is non-magnetic and possesses an ultra-high tensile strength and provides for good ductility. This alloy has a maximum 750 degree F temperature capability. In addition, it has excellent corrosion resistance to chloride solutions, mineral acids, and in hydrogen sulfides.
The ability of MP35N® to resist stress-corrosion and crevice corrosion often leads to its selection as a fastener material, although its uses also include petrochemical equipment, racing engines and submersibles as well as medical devices and dental equipment. This alloy is typically work-strengthened and aged to obtain strength levels of 260 to 300 ksi.
