The high-carbon high-chromium steel have been widely used for punching dies of silicon steel plates and other mild steel plates, and also used for materials of precise gauges, because of their small distortion characteristics after heat treatments. This feature is resulted from the fact that these steels are fully hardened by air cooling.
From the general fact that the higher the quenching temperature, the larger the distortion ratio becomes, quenching temperature to get equal quenched hardness must be as low as possible. Standing on this view point, the authors studied the effect of nickel addition to such steel and found that about 0.5% addition of Ni was most effective.
