◎ Temperatures of solution annealing shall be agreed for simulated heat-treated test-pieces. ① If heat-treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded. ② After martensitic transformation.Solution annealing at 1025℃ to 1055℃ will be necessary before precipitation hardening. |
