Ground Flat Stock

Uses of Ground Flat StockO1 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 AnalysisThe material is supplied in the annealed condition, free of decarburization on all machined surfaces.A.I.S.I.
