ANNEALING can be done by heating to temperatures ranging from 1,290

to 1,380 deg.F. and cooling in air or quenching in water or oil. After

this treatment the forgings will have a hardness of about 200 Brinell

and a tensile strength of 100,000 to 112,000 lb. per square inch.

If softer forgings are desired they can be heated to a temperature

of from 1,560 to 1,650 deg.F. and cooled very slowly. Although softer

the forgings will not machine as smoothly as when annealed at the

lower temperature.
