Because of this, the tool steel used in these dies becomes extremely important in the die life and productivity rates of these specialized stamping lines. Over the past few years, some tool steel suppliers have taken their generic hot work tool steels and marketed them for hot stamping applications. These will work in some cases but will not result in maximized performance of the tooling. Dörrenberg Steel has developed two tool steel grades specifically for these hot stamping applications. Each grade has unique characteristics to increase wear resistance, thermal conductivity and tool life. giving the customer the best option to meet their line objectives. Both grades are in use in hot stamping lines around the world with customers speaking highly of the results achieved.
