COMMENTS:

Material is produced in the “Cold Rolled” / Annealed condition.  After coiling springs should be aged to the H 900 condition.  Bars with hardness value of HRC 44 will have estimated tensile of  200 KSI.  As a general rule, bar lengths are 12 feet long.  Some sizes are available up to 20 feet in length.
Check with a Suhm representative to verify lengths.
