  • High manganese 3generation advanced high strength steels
    Patent number: 11136656
    Abstract: A high strength steel comprises up to about 0.25 wt % C, up to about 2.0 wt % Si, up to about 2.0 wt % Cr, up to 14% Mn, and less than 0.5% Ni. It preferably has an Ms temperature less than 50° C. The high strength steel may have a tensile strength of at least 1000 MPa and total elongations of at least about 25% after hot rolling. It may have a tensile strength of at least 1200 MPa and total elongations of at least about 20% after hot rolling.
    Type: Grant
    Filed: May 20, 2016
    Date of Patent: October 5, 2021
    Assignee: Cleveland-Cliffs Steel Properties Inc.
    Inventors: Luis Gonzalo Garza-Martinez, Grant Aaron Thomas, Amrinder Singh Gill
  • COLD ROLLED ENAMELING SHEET STEEL WITH ENHANCED FORMABILITY AND PROCESS FOR MANUFACTURING SAME
    Publication number: 20210130938
    Abstract: A cold-rolled enameling sheet steel has equivalent or better properties than the prior art Type 1 enameling sheet steel and approaches the formability of a Type 3 enameling sheet steel.
    Type: Application

  • Reduction at elevated temperature of coated steels containing metastable austenite
    Patent number: 10711320
    Abstract: Warming a metastable steel after coating and before or during cold rolling suppresses the transformation of austenite to martensite, resulting in lower mill loads and higher amounts of reduction at similar loads. As-warm rolled steel has enhanced mechanical properties when compared to steel reduced the same amount by cold rolling at room temperature.

    Assignee: AK Steel Properties, Inc.
    Inventors: Amrinder Singh Gill, Erik James Pavlina, Paul Valdas Janavicius
  • REDUCTION AT ELEVATED TEMPERATURE OF COATED STEELS CONTAINING METASTABLE AUSTENITE
    Publication number: 20190284655
    Abstract: Warming a metastable steel after coating and before or during cold rolling suppresses the transformation of austenite to martensite, resulting in lower mill loads and higher amounts of reduction at similar loads. As-warm rolled steel has enhanced mechanical properties when compared to steel reduced the same amount by cold rolling at room temperature.

  • WARM ROLLING OF STEELS CONTAINING METASTABLE AUSTENITE
    Publication number: 20170204493
    Abstract: Warming a metastable steel before or during cold rolling suppresses the transformation of austenite to martensite, resulting in lower mill loads and higher amounts of reduction at similar loads. As-warm rolled steel has enhanced mechanical properties when compared to steel reduced the same amount by cold rolling. Warm rolling followed by subsequent annealing also results in better mechanical properties than those achieved in material cold rolled the same amount and then annealed.
