STRESSPROOF® is made by a patented process which consists of drawing the bar through a special die under heavy draft, then stress relieving it. This severe cold working combined with the stress relieving results in a high strength bar with good stability and exceptional machinability. STRESSPROOF® can often replace heat treated alloy steel for machined parts requiring hardness in the range 23-30 HRC. It can be induction hardened but should be watched for quench cracks because of the high sulfur and manganese content. Welding is not recommended. STRESSPROOF® exceeds ASTM A311, Class B.
