Uses
of Ground Flat Stock
O1 is a medium alloyed oil hardening steel with excellent cutting force
and toughness, the excellent dimensional stability reduces distortion
and the possibility of cracking during heat treatment.
Supplied in the annealed condition, the precision tolerances minimise
additional costly tool room machining.
Ground Flat Stock provides toolmakers with a decarburization free
surface, plus a high wear resistance after heat treatment, making
it ideal for a multitude of uses and applications: dies, press tools,
punches, gauges, cams, jigs, machine knives and marking devices.
Material & Technical Analysis
The material is supplied in the annealed condition,
free of decarburization on all machined surfaces.
