Cutting-off Steel From Bar






Category: HIGH-SPEED STEEL

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 to
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.
