... Abstract Two slitting saw blades were delivered for the purpose of determining the cause of damage. One had cracked while the other one came from a prior sheet delivery, that had less tendency to crack formation according to the manufacturer. The blades were supposed to have been stamped out...

... in the throughthickness direction; saw-cuts parallel to the surfaces were made along the ends of strips cut from the back plate, into which a chisel was inserted in order to try to split the plate. No pronounced weakness in this direction was revealed, the two portions of the plate bending at the end of the saw-cuts...

..., mechanical properties, and fine fracture features are altered by tempering, a very hard piece should not be tempered to facilitate saw cutting. Rather, abrasive blade cutting or some other techniques should be used that will not alter the as-received condition. Burning (i.e., oxyacetylene or plasma arc...
