Material Notes:
MP159 is an alloy of the Multiphase family of alloys possessing the unique combination of ultra-high strength, ductility and corrosion resistance. Through work strengthening and aging, MP159 alloy exhibits ultimate tensile strength levels in excess of 265,000 psi while maintaining reduction of area values greater than 30%. Excellent strength and ductility are also evident at elevated temperatures up to 1100 - 1200 °F. MP159 alloy is produced by vacuum induction melting followed by VAC-ARC remelting to provide optimum control of chemistry and preferred ingot solidification.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
