COMMENTS:

Material is produced in either the solution annealed or solution annealed/aged condition.    This specification only requires that minimum strength values be met.  If necessary check with a Suhm representative to obtain actual capabilities for tensile and yield.  Aging time and temperatures are extensive (20 Hrs. @ 1300F) to produce the required strengths.

Bar lengths in general will average 12 to 14; however, Suhm maintains a stocking arrangement to
have available 10 - 20 lengths on some sizes. Some sizes are available in lengths up to 35'.  Check with a Suhm representative to verify sizes and lengths.

 

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.
