Press-formed article, and manufacturing method for same

2013 
When manufacturing a molded article by using a metal mold having a punch and a die to press mold a steel sheet, after heating the steel sheet to a temperature which is at least equal to an Ac 1 transformation point, by initiating molding after the sheet has cooled to 650°C or less and keeping the friction coefficient between the metal mold and the steel sheet during molding at 0.3 or less, this method can be used to manufacture a press-formed article having such excellent moldability that deep-drawing processing is possible.
