Applicability and limitations
Original 2012 Table 1: ladle composition, mass fraction (wt%); applicability and deviations for product analysis must be checked separately under 4.3 and Table 5. Grade designations and product forms are retained as listed in the standard; cold-heading suitability is not implied. Note B: Si is an order-specific option; if not specified, it is unknown, not zero. Note C: Cu ≥0.20% applies only when ordered; no upper limit is invented, and ordinary orders do not automatically include Cu. Note D: Pb 0.15–0.35% applies only to an expressly designated leaded L grade; Pb is not added automatically to grades without L. Note F: additions of Bi/Ca/Se/Te are determined by agreement between purchaser and supplier; absent a specified value, they are not zero. Note E: boron treatment gives an expected content under specified conditions and is not a uniform B limit for all ordinary grades.

Applicability and limitations
ASTM A29/A29M-2023 original Table 1: base entries are ladle-analysis mass fraction wt%; product-analysis tolerances are checked separately under 4.3 and Table 5, not added to ladle limits. Orders by Table 1 grade must meet its ladle limits under 4.1.1; other ordered chemistries are separately agreed under 4.1.2 and Tables 3/4 and must not be mixed into this table. General hot-wrought bar requirements do not, by chemistry alone, establish cold-heading suitability, supply or mechanical properties. Note B: the Si range is a common option only when required by the order; Si is unspecified by default, not a universal range or zero. Note C: Cu≥0.20% applies only when expressly required by the order and has no added upper limit. Note D: leaded steel Pb is 0.15–0.35%; retain L as part of the grade identity, not ordinary grades. If lead is added to the ladle stream, its cast or ladle-analysis value cannot be determined. Note F: Bi/Ca/Se/Te are specified by buyer-supplier agreement; do not enter zero when no value is given. Note E: only for expressly specified boron treatment of killed steel, expected B is 0.0005–0.003%; where usual Ti addition is not permitted, up to 0.005% may be expected. These are not mandatory B limits for all ordinary grades.
