Applicability and limitations
ASTM A576-17 applies to hot-worked bars of quality carbon steel; Table 1 gives ladle chemistry. It must not be assumed to guarantee wire-rod supply or finished cold-heading properties. Table 1 note C: Si, when needed, is agreed at order; common options are ≤0.10, 0.10–0.20, 0.15–0.35 or 0.20–0.40%. Without agreement, do not assign a fixed Si value. Table 1 note D: Cu ≥0.20% may be specified when required; this is conditional. Notes E/F/G: Pb, B and Bi/Ca/Se/Te apply when specified; do not automatically add Pb or a B minimum to all grades. Clause 7.1 requires reporting Cu/Cr/Ni/Mo/V/Nb contents; a reporting requirement does not mean Table 1 sets limits for these elements. Clause 5.1 allows other chemical ranges to be agreed under Table 2; Table 2 is not a mandatory set of additional limits for every Table 1 grade.
