Suggestions For Handling High-speed Steels






Category: HIGH-SPEED STEEL

The following suggestions for handling high-speed steels are given
by a maker whose steel is probably typical of a number of different
makes, so that they will be found useful in other cases as well.
These include hints as to forging as well as hardening, together
with a list of dont's which are often very useful. This applies
to forging, hardening of lathe, slotting, planing and all similar
tools.


and larger is usually mild finished, and can be cut in a hack saw.
If cut off hot, be sure to heat the butt end slowly and thoroughly
in a clean fire. Rapid and insufficient heating invariably cracks
the steel. If you want to stamp the end with the name of the steel,
it is necessary that this is done at a good high orange color heat,
as it is otherwise apt to split the steel. (Take your time, do
not hurry.)]
