The main requirement for heat treatment of die-cast steels is the ability to harden, resulting in the purchase of the required hardness, mechanical strength — compression, tensile, bending, as well as resistance to abrasion, dynamic and shock loads.
Hardenability
Hardening increases the hardness of the material, which is retained after tempering, while reducing brittleness. The hardenability depends on the amount of residual austenite that remains in the structure during the pearlite and intermediate transformations. Of particular importance is the rate of martensitic transformation, which is determined by the presence of certain alloying elements. The hardenability also depends on the dimensions of the workpiece and the depth of heating of the surface.
Perlite and bainitic transformation
The condition for increasing the hardening of stamped steels is the prevention of pearlitic and bainitic transformations. To do this, set a certain minimum quenching rate, which depends on the amount of carbon in the composition, as well as the degree of doping of the austenite. For low-alloyed stamped steel grades, the critical quenching rate should be at least 250… 400 deg / s, for medium-alloy grades 35… 40 deg / s, and for high-chromium and high-alloy steels — not less than 10… 15 deg / s.
