COMMENTS:

There is currently not a standard/specification which covers tensile/yield strength values for spring tempered wire.  Tensile strength should be comparable to Inconel X750, however please check with a Suhm representative for actual strength values.  Larger sizes can be attained in the spring tempered conditions.  Also bar stock is available in the solution annealed/aged condition.  Check with a Suhm representative for further information.

 

These data are provided as a reference guide only and are not intended for design purposes.  Strength values and sizes are subject to change.  Please check with a Suhm Spring representative for confirmation.
