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. @ 1300ºF) 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.
