Composition based on ISO 4954:2018; the product edition is unspecified, so confirm the edition applicable to the contract.

ISO 4954:2018, Table B.2 gives heat analysis; A single value is a maximum; a dash is not zero. ; Product-analysis tolerances are listed separately under Table 2/3 of the standard and do not directly widen the heat-analysis composition ranges. ; Optional Al0.020–0.050% to improve cold-heading performance; this is not a universal mandatory minimum. ; Low Si may be agreed in the order, taking hardenability into account; Where hardenability is required, the standard permits limited deviations, except for P/S; C must not exceed 0.01%; see Table 2 for the other requirements.

Heat analysis mass fraction wt%; Allowable deviations for product analysis shall follow Table 4; this table shall not be expanded unconditionally.. ; Si may be agreed at a lower content or a specific range at the time of ordering; the default in this table is ≤0.30%.. ; To improve cold-heading performance, Al 0.020–0.050% may be optionally added (Note 3); Al is not mandatory for all grades. ; Small deviations for hardenability orders must satisfy Note 2 and Table 4.; P/S shall not be relaxed by this means; the default composition table shall not be automatically expanded.. ; Elements not listed shall not be intentionally added without the purchaser's consent (except additions needed to finish steelmaking); unspecified does not represent zero.. ; This standard is for cold-heading and cold-extrusion, but specific product supply still requires confirmation of dimensions, delivery condition, surface, and performance requirements..

Mass fraction wt%; Table B.2 heat analysis; see Table 2 separately for product-analysis tolerances. ; Note a: Al≤0.050% may be added to improve cold heading, but is not mandatory by default. ; Note c: A lower Si or a specified Si range may be requested by agreement; specific agreements have not yet been provided and shall not be filled in arbitrarily. ; When hardenability requirements exist, the small deviations permitted in Table B.6/B.7 must be verified separately according to Table 2 and conditions; the default composition range shall not be expanded. ; Elements not listed must not be intentionally added without purchaser consent, except additions needed to finish steelmaking; Unspecified values are not treated as zero. ; Mechanical properties/hardenability have not been supplemented in this batch; Cold heading applicability must be determined in conjunction with dimensions, state, and technical conditions.

The original webpage states DIN EN 10263-3-2018; The composition in this record was actually verified against DIN EN 10263-3-2002, Table 2; the edition is now identified as 2002 according to the original evidence; See the separate complete-table record for edition 2018. ; Original DIN EN10263-3 Februar2002 expressly adopts EN10263-3:2001; Composition follows PDF8, Table 2; 2017 is not applied across editions. ; Heat analysis wt%; Si≤.30; a lower content or specified range may be agreed at ordering, but no option is selected without an agreement. ; Note b: hardenability-based orders permit only small deviations, C .01 and the other elements in Table 3; P/S is not applicable; Default limits are not widened; product-analysis tolerances require separate verification. ; Note a: unlisted elements must not be intentionally added except to finish the heat; Residual elements must not impair mechanical properties or end use; unspecified values are not entered as zero. ; The historical table has no general optional Al range under 2017, note 3; the Al option from a later edition is not copied. ; This part covers carburizing steels for cold heading/cold extrusion; dimensions, delivery condition, surface and actual supply still require confirmation.

DIN EN 10263-3:2018-02 is the German-language edition of EN 10263-3:2017; Verified according to the heat analysis and notes of Table 3 in the German official version.. ; Table 3 of DIN EN 10263-3:2018-02 specifies the heat analysis mass fraction in wt%.; Allowable deviations for product analysis shall follow Table 4; this table shall not be expanded unconditionally.. ; Si may be agreed at a lower content or a specific range at the time of ordering; the default in this table is ≤0.30%.. ; To improve cold-heading performance, Note 3 of Table 3 allows the optional addition of Al 0.020–0.050%.; This composition variant shall be applied only when explicitly selected.. ; Small deviations for hardenability orders must satisfy Note 2 and Table 4.; P/S shall not be relaxed by this means; the default composition table shall not be automatically expanded.. ; Elements not listed shall not be intentionally added without the purchaser's consent (except additions needed to finish steelmaking); unspecified does not represent zero.. ; This standard is for cold-heading and cold-extrusion, but specific product supply still requires confirmation of dimensions, delivery condition, surface, and performance requirements..

Baosteel BEXG 021-2020, Table 1, row 84, PDF page 9; heat-analysis composition in wt%, hot-rolled wire rod. 2020 is the original edition available locally, with no claim that it is the company’s current latest edition. Special conditions and actual supply require separate confirmation.

Give priority to the published technical page on the Creation Group website. Use local reference ranges only as supplementary composition cross-checks; the applicable standard for that product page, the technical agreement and actual verification take precedence.
