New steel is a general-purpose steel for cold work dies with low hardenability and high carbon steel with a carbon mass fraction above
.
.New The advantages of this steel are good processability, high hardness and toughness, but low hardenability and large quenching deformation. Because steel contains few alloying elements, its tempering resistance is low, and its hardened layer is shallow, so its load-bearing capacity is low. It has high hardness and wear resistance, and is less sensitive to grain growth.
