Analysis
| Carbon | 0.40-0.50% | Chromium | 1.20-1.50% |
| Manganese | 0.15-0.45% | Silicon | 0.10-0.40% |
| Sulphur | 0.03% max | Nickel | 3.80-4.30% |
| Phosphorous | 0.03% max | Molybdenum | 0.15-0.35% |
Forging
Heat the component slowly and uniformly to 1050°C. Re heat the X45NiCrMo4 as necessary and avoid working below a temperature of 850°C. After forging the steel cool slowly in furnace, thermoinsulating material.
Annealing
As this grade is supplied in the annealed and machineable condition re-annealing will only be necessary if the steel has been forged or hardened. Heat the steel uniformly to 630-650°C. Soak well then slowly cool in the furnace to approximately 600°C and then cool in air.
Stress Relieving
When dies produced in X45NiCrMo4 steel are heavily machined, it is recommended to stabilise just before finish machining in order to relieve machining strains. Heat to approximately 650°C soak well and allow to cool in air.
Hardening
Pre heat the steel slowly and uniformly to a temperature between 650-700°C and soak thoroughly. Continue heating the component to afinal hardening temperature of 840-870°C and allow the component to be heated through. Quench the steel in oil or cool in air.
Tempering
Slowly heat the steel component uniformly and thoroughly to the selected tempering temperatures and hold the X45NiCrMo4 component at heat for one hour per 25mm of thickness, but for a minimum of two hours. Cool in air. This grade of steel can be hardened by vacuum furnace and gas quench processes.
