The hardness out of factory is 35~39HRC
Features: 718H is alloy steel including Cr, Ni, and Mu which melt in the vacuum State. They haven’t other hot treat deformation risk. They can cut down the cycle of mould making .And mould is easy to amend.
The main usage of 718H: The large scale longevity injection mould. Like consumer electronics. Computer crust and so on .Some high smooth finish plastic mold.
Blow mould, due to the high hardness, can be used for slider in the plastic mould, Forming tools, compression - braking mode (bay trigger mode), (depending on production needs can be applied flame hardening or nit riding process), some tectonic components and axis.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
