| StressProof® is made by a patented process which consists of drawing the bar through a special die under heavy draft, then stress relieving it in a precisely controlled furnace. StressProof® offers wearability without case hardening, strength without heat treating, plus excellent machinability and tool life. Other benefits include resistance to fatigue and stress, balanced working, and minimum warpage and distortion. StressProof® can also be induction hardened but should be watched for quench cracks, and, being a resulfurized steel, a magnetic particle inspection operation should be performed after heat treating.Information provided by Niagra LaSalle Corporation |
