MS JN/HBW555XCr27 Heat Treatments
- Typical heat treatments are hardening, tempering, soft annealing and annealing.
A typical hardening cycle is: slowly heating up to a temperature within the range of 900°C to 1050°C, holding for a determined period of time and then rapidly cooling.
A typical tempering cycle involves: slowly heating up to a temperature within the range of 200°C to 550°C, holding for a period of time appropriate to the thickness, followed by air or furnace cooling.
If casting hardness below HBW 378 is required (e.g. to facilitate machining), soft annealing can be carried out. An example of a soft annealing method is: slowly heating up to a temperature within the range of 920°C to 975°C, holding for at least 1 h, then slowly cooling down in the furnace to about 810°C and then further cooling down to 600 °C at a rate not exceeding 55 K/h, followed by air or furnace cooling.
If castings require annealing then a typical annealing involves slowly heating up to a temperature of 700 °C to 750 °C for a minimum of 4 h, and then slowly cooling in the furnace to 600 °C, following by air or furnace cooling.
