Tool Or Crucible Steel






Category: ANNEALING

Crucible steel can be annealed either in muffled furnace or by
being packed. Packing is by far the most satisfactory method as it
prevents scaling, local hard spots, uneven annealing, or violent
changes in shape. It should be brought up slowly to just above
its calescent or hardening temperature. The operator must know
before setting his heats the temperature at which the different
carbon content steels are hardened. The higher the carbon contents
the lower is the hardening heat, but this should in no case be
less than 1,450 deg.F.
