| ◎ a=air; o=oil; w=water. ◎ The temperatures of annealing should be agreed for simulated heat treated test pieces. ① Solution annealing in the range specified followed by sufficiently rapid cooling to avoid precipitation of deleterious phases is essential after hot forming these steets. ② If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded. |
