Ground Flat Stock
Precision ground flat stock / gauge plate can be produced. Subject to size suitability and availability of raw material pieces can be produced in approximately 2 to 3 weeks. Standard and non-standard sizes are available.
Forging
Pre heat slowly and uniformly to 850-900°C. The heat should then be increased more quickly to the forging temperature of 1050-1150°C. If during the forging the temperature of the material drops below 880-900°C, re heating will be necessary. Cool the component very slowly after forging.
Annealing
Annealing is recommended after hot working and before re hardening. Heat to 850°C at a rate of no more than 220°C per hour. Always hold at temperature for one hour per 25mm of thickness (with two hours being minimum). Furnace cool slowly. The annealed hardness achieved should be 248 Brinell or lower.
Stress Relieving
If tools are heavily machined or ground it is recommended to stress relieve after machining and prior to hardening to minimise the possibility of distortion. To stress relieve heat the component to 675-725°C and soak well (approx 2 hours), then cool in air. The 1.3343 tools can be finish machined before heat treatment.
Hardening
Pre heat the component in two steps; 450-500°C then 850-900°C. Continue heating to the final hardening temperature of 1200-1250°C and ensure that the component 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 tools 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. 1.3343 high speed steel is also suitable for vacuum hardening.
