Intended primarily for hot heated bolts but is of somewhat inferior quality, as to surface seams and cracks compared to forging quality, see X1. Wire shall be excluded from these requirements. Material is thermally treated to relieve the major portion of the internal stresses resulting from cold-working and may have a very thin light to medium oxide.
