E52100

Original SAE E52100 corresponds to UNS G52986; UNS is retained only as a search alias. ; Heat analysis wt%; Residual Cu≤.35%, Ni≤.25%, Cr≤.20% and Mo≤.06% are unspecified; explicit alloy ranges take precedence. ; Default and agreed P/S conditions are retained separately; Product-analysis tolerances under J409 require separate verification. ; Other Si ranges require agreement; Addition of Pb requires the L designation; ordinary grades do not include Pb. ; Required reporting of elements and reporting thresholds does not establish universal content requirements or zero content. ; Composition alone does not establish cold-heading suitability or supply availability. ; Note 2, electric-furnace steel; The E prefix and UNS number are retained as in the original table. ; In this original-table row, all P/S are ≤.025%; Agreed widening for ordinary rows is not applied automatically.

Ladle chemical composition, mass fraction wt%; product-analysis deviations are specified separately in Table 6 and are not added to ladle limits. Table 2 Note 1: for Cu/Ni/Cr/Mo not specified as alloy ranges, the respective maxima are 0.35/0.25/0.20/0.06%; an explicitly specified alloy range takes priority. Note A: the purchaser may specify Si ≤ 0.10% as a separate condition from the tabulated Si range; the conditions are not combined. Note 4: Pb at 0.15–0.35% applies only to a separately specified L leaded grade; Pb is not added to ordinary grades. This is a general requirement for hot-worked bars; chemical composition alone does not establish cold-heading suitability or supply.

Standard dated 2000-6, Table 1; ladle analysis, mass fraction wt%.; Product analysis deviations shall be verified separately according to SAE J409, and shall not directly expand the table values. Note 1: For elements neither specified nor required in the original table, residual upper limits apply: Cu/Ni/Cr/Mo respectively ≤0.35/0.25/0.20/0.06%; Explicit alloy ranges shall take priority. Pb 0.15–0.35% must be separately specified as L-grade; it is not automatically added to ordinary grades. Al, Ti, Nb, and V must be reported regardless of whether they are specified; Values below 0.008% may be reported as <0.008%; this is a reporting threshold, not a uniform composition upper limit. Grades with E prefix are electric furnace steels, with P/S upper limits of 0.025% respectively, separated from ordinary grades. Applicable to billets, slabs, plate, wire rod and hot-rolled/cold-worked bar products, among other forms.; Chemical composition itself does not guarantee suitability for cold heading.

Original ASTM A29/A29M-2023 Table 2: the basic table values are ladle-analysis mass fractions (wt%); product-analysis deviations must be checked separately under 4.3 and Table 6 and are not added to ladle limits. Under 4.1.1, an order for a grade in this table must meet its corresponding ladle limits; other ordered compositions are agreed separately under 4.1.2 and Tables 3/4 and are not silently mixed into this table. These are general requirements for hot-worked bars; chemistry alone does not establish suitability or supply for cold heading, or mechanical properties. Table 2 note 1: where no alloy range is specified, residual maxima are Cu/Ni/Cr/Mo 0.35/0.25/0.20/0.06%, respectively; ranges specified for the row take precedence. Table 2 note A: the purchaser may specify Si ≤0.10% as an alternative branch to the row’s Si range; the two are not combined. Table 2 note 4: Pb 0.15–0.35% applies only to a separately designated L grade. When lead is added to the ladle stream, its cast/ladle analysis cannot be determined; this does not automatically create a leaded grade or add Pb to ordinary grades.
