Heat treatment for the test pieces of 708M20 forged parts:
Soft Annealing
Heat to 680-700c, cool slowly ib furnace. This will produce a maximum Brinell hardness of 207.
Normalizing
Normalizing temperature: 860-900c.
Hardening
Harden from a temperature of 850-880c followed by oil or water quenching. Hardness afterquenching is 39-47 HRC.
Tempering
Tempering temperature: 595-700c.
