Abstract

PURPOSE: To produce die steel for diecasting which, due to its low carbon content and Ni contained in it, indicate low carbon precipitation in crystal boundary and high toughness after annealing even at a low cooling rate as in box-hardening. Co contained in the steel leads to a high matrix strength and high heat fatigue strength.
