Abstract: A method for forming a stainless steel sink bowl having a top edge, a sidewall and a bottom surface interconnected by smooth corner surfaces from a single sheet is provided. The method comprises drawing a stainless steel blank between a first draw die and a first forming die to form a first drawn blank having an unfinished bowl with a length, width and depth which are less than the finished length and width and generating a deformation warmth in the blank at the corner surfaces in proximity to the rim as the first drawn blank is being formed to a temperature of approximately 70.degree. C. to 90.degree. C. The first drawn blank is immediately removed from the first draw die and the first forming die and transferred to a finish draw die.
