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.

Applicability and limitations
Table 1: UNS G10700 corresponds to SAE 1070; heat analysis, wt%. Si is not a universally mandatory constituent. When specified, common limits for bars/semi-finished products are ≤.10, .10–.20, .15–.35, .20–.40 and .30–.60%; wire rod also has the .07–.15% option. This record does not select a range without agreement. When Cu is required, ≥.20% is generally specified; this is neither a universal upper limit for Cu nor a default requirement. Addition of Pb at .15–.35% requires the L designation and a change to UNS; addition of B at .0005–.003% requires the B designation. These treatments are not included in ordinary grades. Lower P/S limits for certain qualities/products require separate verification against J411; agreement values from later editions are not imported. A requirement to report additional elements does not establish universal limits in this table. Unspecified Si/Cr/Ni/Mo and other elements are not assigned zero. Product-analysis deviations under J409 require separate verification.

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.

Nippon Steel wire rod catalogue EXE203 (historical material, 2008.3), PDF p. 7
printed p. 10, SAE J403 NOV.2001. The source table does not specify the analysis type. Manufacturer-range data, not a standard-guaranteed value or heat-lot test, and not a representation of our supply. Condition: Si is an optional value subject to agreement as stated in the source; do not select by default or merge into one broad range. Until selected, do not use it in a complete calculation or assessment. Pb 0.15–0.35 and B 0.0005–0.0030 are optional additions with L/B designation; do not add them automatically to ordinary grades. Special low-P/S quality requires separate agreement verification.
Composition conditions
- Original catalogue mass percentages, historical manufacturer data from 2008.3; Referenced standard names and editions follow the original document; this does not establish that the official texts of those standards have been obtained and verified.
- A dash or blank must not be treated as 0; only chemical composition has been checked in this batch. Mechanical properties and actual supply require separate verification under the applicable conditions.
- Si follows the agreed options in the original text; no option is selected by default, and the options are not merged into one wider range; If not selected, it is excluded from complete calculations or assessments.
- Pb 0.15–0.35 and B 0.0005–0.0030 are options requiring an additional L/B designation and are not automatically included in ordinary grades in the original table; Special-quality low P/S requires separate verification of the agreement.
Verification notes
Grouped tables were expanded in full and checked against original images and notes. Ordinary, residual and conditional elements are kept separate; suffix tables lacking complete base-steel composition are excluded.1070 · CHINA STEEL CORPORATION · Bars and Wire Rods Product Catalogue 2014-C1 / 7.1.15 SAE · Carbon steels (Edition unspecified)

IIW / CEV：0.7500–0.9000Known-element contribution; incomplete value; missing Cr, Mo, V, Ni, Cu; ordering or conditional requirements remain unresolved CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15; an engineering estimate of welding cold-cracking susceptibility for carbon and low-alloy steels.
Pcm（Ito–Bessyo）：0.6800–0.7950Known-element contribution; incomplete value; missing Si, Cu, Cr, Ni, Mo, V, B; ordering or conditional requirements remain unresolved Pcm = C + Si/30 + (Mn + Cu + Cr)/20 + Ni/60 + Mo/15 + V/10 + 5B; mainly used for low-carbon low-alloy steels, particularly modern low-carbon pipeline steels; more relevant when C is approximately no higher than 0.11%.

Applicability and limitations
China Steel bar and wire rod catalogue CAT.NO.3-BD-01-2014-C1, PDF p. 22
printed p. 20, §7.1.15 SAE carbon steels (edition not marked). The source table does not specify the analysis type. Historical manufacturer range data, not a standard-guaranteed value or heat-lot test, and not a representation of our supply. Conditions: Si is an agreement-based option, with separate options for bar and wire rod; B is not automatically added to the ordinary grades in the source table. Where Cu is specified, it is generally ≥0.20%; this is not a default Cu minimum for all steels.
Composition conditions
- Historical manufacturer 2014-C1 catalogue, bars/wire rod; Where the referenced standard edition is not identified, a year is not borrowed from another catalogue; a catalogue is not upgraded to the official standard text.
- A dash or blank must not be treated as zero. Composition data do not establish completeness or applicability of a formula; mechanical properties and supply require separate verification.
- Si is an optional agreement condition, with separate options for bars and wire rod; B is not automatically added to ordinary grades. Where Cu is required, it is usually ≥0.20%; this is not a default Cu minimum for all grades.
Verification notes
Merged cells in all 28 catalogue tables were reconstructed geometrically, with no missing cells. Original images, continuation pages and notes are recorded; disputed conditions are withheld.1070 · ASTM A29/A29M-2020
