Abstract (en)
[origin: DE102007039013B3] The production process involves creating the strip from heat-treated steel, heating it while wound as an open coil within austenitizing temperature limits, keeping it incandescent in a carbon-free atmosphere for at least 90 minutes, in which the atmosphere absorbs carbon from the steel, and cooling at an accelerated rate.
