Notes and Changes:
CFW requested the following changes:
Changed heat treat from HRD to Stress Relieved. (Note that the UTS remains the same)
Changed Minimum Cast at 12" from 12" to 8". This defines the minimum coiled diameter when the wire is uncoiled. The wire probably won't be any worse than the last deliveries but rather CFW doesn't want to be right at the tolerance limit.
