    Type: Application
    Filed: February 11, 2026
    Publication date: August 13, 2026
    Inventors: Elizabeth Nicometo, Maarten De Jong, Cagatay Yanar, James A. Curran, Ethan E. Currens, Zechariah D. Feinberg, Brian M. Gable, Abhijeet Misra, James A. Yurko, Hossein Seyedrezai, Herng-Jeng Jou
  • Steel compositions and solution nitriding of stainless steel thereof
    Patent number: 11021782
    Abstract: The disclosure provides methods of making iron-based alloys, as well as resulting alloys. An iron-based alloy containing a small amount of nickel (e.g., 0.5 to 2.0 wt %) is annealed and machined. The alloy is sufficiently ductile to reduce the likelihood of cracking, while not sufficiently high to result in a hardened alloy. After the alloy is shaped, the alloy is hardened by nitriding.
    Type: Grant
