  • Heat Treatment Of Sheet Steel (AREA)

Abstract

PURPOSE: To manufacture the cold rolled steel sheet possessing excellent press formability and baking hardenability, by applying the specified heat treatment and temper rolling processes to the steel possessing the specified composition after carrying out the hot rolling, the pickling and the cold rolling.
CONSTITUTION: The steel is specified to possess following composition; 0.003W 0.02% C, 0.2% or less Si, 0.03W0.25% Mn, 0.03W0.2% P, 0.02W0.15% Sol.Al, 0.002W0.015% N, and the balance Fe; this steel is hot rolled, pickled, and cold rolled in this order, and the cold rolled steel sheet is prepared. Next, this cold rolled steel sheet is treated for the recrystallization annealing at ≥600°C temperatures; hereafter, the cooling process is carried out so as to keep the average cooling rate at 10W250°C/h over 400W200°C the temperature region. Hereafter, this steel sheet is subjected to the temper rolling process.
