Conclusions
-
1.
The wear resistance of 5KhNT dies pressed during crystallization is close to that of forged dies.
-
2.
The high wear resistance and durability of 5KhNT dies pressed during crystallization are due to the favorable arrangement of crystals in relation to the operating stresses.
-
3.
The strength of steel 5KhNT pressed during crystallization is higher than that of dies cast in sand molds and approximates that of forged dies.
