Heat treatment of 1.6587 steel:

Soft Annealing: Heat 17CrNiMo6 to 650-700℃, cool slowly in furnace. This will produce a maximum Brinell hardness of 229.

Normalizing: 850-880℃, air.

Hardening: Carburising: 880-980oC. Core Hardening: 830-870℃, water. Case Hardening: 780-820℃, water.

Tempering: Temperature: 150-200℃

Forging: Hot forming temperature: 1100-900℃.
