Ground Flat Stock
Precision ground flat stock / gauge plate can be produced. Subject to the size suitability and availability of raw material pieces can be produced in approximately 3 to 4 weeks. Standard and non-standard sizes can be produced.
Forging
Pre heat slowly to 850-900°C. The heat should be increased more quickly to the forging temperature of 1050-1150°C. If during the forging the temperature of the steel drops below 880-900°C then re heating will be necessary. After forging cool the component very slowly.
Annealing
Annealing is always recommended after hot working and before re hardening. Heat the steel to 850°C at a rate of no more than 220°C per hour. Hold at temperature for one hour per 25mm of thickness (with two hours being the minimum). Furnace cool slowly.
Stress Relieving
After heavy machining and prior to hardening it is recommended to stress relieve to minimise the possibility of distortion. To stress relieve the steel heat the component to 675-725°C and soak well (approx 2 hours), then cool in air.
Hardening
Pre heat the component to 450-500°C then up 850-900°C. Continue to heat to the final hardening temperature of 1200-1250°C and ensure that the steel is heated through. Care must be taken to not allow the component to remain too long at the hardening temperature. Quench in warm oil or salt. If quenching in salt allow the components to equalize, then complete the quench in air. If quenching in oil remove the component from the oil at about 500°C and then air cool. It is also suitable for vacuum hardening.
