Featured snippet from the web
A311 Class B StressProof® Cold Finished Steel Bar is produced using a proprietary process that draws the bar through a special die under heavy draft. A311 Stressproof® Bar is a medium carbon free machining steel. The bar is then stress relieved in a precisely controlled furnace. The result is a steel bar product that meets stringent standards that provide a wide variety of benefits, including:
Improved wearability without case hardening
Strength without heat treating
Exceptional surface quality
Excellent machinability
Extended tool life
Resistance to fatigue and stress
Balanced working
Minimized warpage and distortion
Controlled low stresses
StressProof® is electro-magnetically tested using eddy currents. Although it also can be induction hardened, it should be watched for quench cracks.
