AS JN/HBW555XCr21 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, 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. 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.
