Comments
Material is produced in the “Cold Rolled” / Annealed condition. After coiling springs should be aged to the H 900 condition. Rockwell C should average 44 R^c with an 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.
