P20+Ni steel also can be called DIN 1.2738 steel. It has great mechanical property and processability. And it is great choice for the production of the hot work mold base. It always is used for plastic mold base. By the way, the special preheat will make it get better hardness after the production fished on the factory. That will increase the productivity effect of the mold base, make the business get better. You can check P20+Ni steel round bar chemical composition as below.
