A576 1044

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.

The chemical composition currently shown is transcribed from the original ASTM A576-2017; The original record cites ASTM A576-2025; that original edition remains unavailable, and differences between editions have not been confirmed. ASTM A576-17 applies to hot-finished bars of quality carbon steel; Table 1 specifies heat analysis; This must not be assumed to guarantee the performance of wire rod or finished cold-heading products.. ; Table 1 Note C: Si shall be according to order agreement when required, commonly ≤0.10, 0.10–0.20, 0.15–0.35, or 0.20–0.40%.; Do not enter a fixed Si value if not agreed upon. ; Table 1 Note D: When Cu is required, Cu≥0.20% may be specified, which is a conditional requirement.. ; Notes E/F/G: Pb, B, and Bi/Ca/Se/Te are all applicable only when specified.; Do not automatically add Pb/B lower limits to all grades. ; Clause 7.1 requires reporting the content of Cu/Cr/Ni/Mo/V/Nb; the reporting requirement is not equivalent to the provision of limits for these elements in Table 1.. ; Clause 5.1 allows other chemical ranges to be agreed upon according to Table 2.; Table 2 does not impose additional mandatory limits on every grade in Table 1..
