Abstract: A HIGH STRENGTH COLD ROLLED STEEL SHEET AND A METHOD OF MANUFACTURING THEREOF The present disclosure discloses a method of producing a high strength cold rolled steel sheet. The method includes casting a steel slab of desired composition, heating the steel slab and subjecting the steel slab to a hot working process to form a steel sheet. After hot rolling, quenching the steel sheet and coil it. After coiling, the steel sheet is cold rolled, followed by continuous annealing heat treatment. After annealing, the steel sheet is subjected to a first cooling process at a first predetermined cooling rate. Further, the steel sheet is held for a time period. Additionally, partitioning and quenching, the steel sheet to obtain the high strength cold rolled steel sheet. The high strength cold rolled steel sheet exhibits ultimate tensile strength (UTS) ranging from 1200 MPa to 2200 MPa. Figure. 1 is a reference figure
