Instructions For Working High-speed Steel






Category: HIGH-SPEED STEEL

Owing to the wide variations in the composition of high-speed steels
by various makers, it is always advisable to follow the directions
of each when using his brand of steel. In the absence of specific
directions the following general suggestions from several makers
will be found helpful.

The Ludlum Steel Company recommend the following:

CUTTING-OFF.--To cut a piece from an annealed bar, cut off with
a hack saw, milling cutter or circular saw. Cut clear through the
bar; do not nick or break. To cut a piece from an unannealed bar,
cut right off with an abrasive saw; do not nick or break. If of
large cross-section, cut off hot with a chisel by first slowly
and uniformly heating the bar, at the point to be cut, to a good
lemon heat, 1,800 deg.-1,850 deg.F. and cut right off while hot; do not nick
or break. Allow the tool length and bar to cool before reheating
for forging.
