Forging High-speed Steel






Category: THE FORGING OF STEEL

Heat very slowly and carefully to from 1,800
to 2,000 deg.F. and forge thoroughly and uniformly. If the forging
operation is prolonged do not continue forging the tool when the
steel begins to stiffen under the hammer. Do not forge below 1,700 deg.F.
(a dark lemon or orange color). Reheat frequently rather than prolong
the hammering at the low heats.

After finishing the forging allow the tool to cool as slowly as
possible in lime or dry ashes; avoid placing the tool on the damp
ground or in a draught of air. Use a good clean fire for heating.
Do not allow the tool to soak at the forging heat. Do not heat any
more of the tool than is necessary in order to forge it to the
desired shape.
