(1) 718H=P20H+1% Ni.
(2) The hardness of 718H steel is 4HRC higher than that of P20H.
(3) P20H is generally used as a less demanding plastic mold or plastic lower mold.718H Good polishing performance Generally used as a plastic mold with polishing requirements.
(4) The 718H die steel is in the annealed state at the factory and the hardness is HB290-310.
(5) The Addition Cure Silicone Material with Concrete Mold is in a pre-hardened state at the factory, and its hardness is HRC28-36.

4.Characteristic
Medium-carbon high-strength carbon structural steel with high strength and hardness after quenching, the steel has mediummachinability, low cold deformation plasticity, poor weldability, no temper brittleness during heat treatment, but lowhardenability, and critical diameter in water 13 * 30mm, and there is a tendency to crack during water quenching. This steel isusually used after heat treatment such as normalizing or quenching and tempering, or high-frequency surface quenching.
