Heat analysis; see the source page for footnotes and agreement-based options. An unspecified range is not zero. The early temporary 2001 extraction has been replaced with the 2017 original. The website does not state an edition; this entry shows the edition of its source and does not establish contractual applicability.

ISO 4954:2018; heat analysis, mass fraction %; values without a stated range are upper limits; see the source page for complete table footnotes. The website does not specify the edition; the source edition is shown here and does not establish contractual applicability.

ISO 4954:2018, Table C.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. ; For C, a range of width 0.04% may be agreed; it does not replace the tabulated range by default.

EN10263-4:2017, Table 3, heat analysis, mass percent. ; Elements not listed shall not be filled as 0; they shall not be intentionally added without the consent of the purchaser, except additions needed to finish steelmaking. ; Note 2 allows the specification of small deviations when hardenability requirements exist, but this does not involve P/S; The default composition range is not expanded here; it must be combined with specific hardenability ordering conditions. ; Note 3 allows Al 0.020–0.050% to be listed separately; it shall not be defaulted as mandatory aluminum content. ; Mechanical properties and delivery conditions are to be verified separately; the standard range is not a guarantee for the forming of arbitrary parts. ; Note a: lower Si may be agreed upon, but the influence on properties such as hardenability must be considered; do not fill in if no specific agreement range is provided. ; Note b allows a C range of 0.04% width by agreement; the example .33–.37 is not a uniform range for all grades.

DIN EN10263-4:2002-02 adopts EN10263-4:2001; the edition relationship is expressly identified on the cover; Heat-analysis mass percentages. ; Historical Table 2/3 contains no optional Al addition note for 2017; newer-edition conditions are not applied. ; Table 2, note c permits an agreed carbon range of width .04%; tabulated defaults are unchanged without a specific agreement. ; Table 2, note d and Table 3, note c permit agreed lower Si, considering effects on properties/hardenability; no range is invented where none is specified. ; Unlisted elements are not entered as zero; Table 2, note a: intentional additions without purchaser consent are prohibited except to finish the heat; residuals may be present but must not impair properties. ; Table 2, note b permits specified deviations where hardenability is required, except for P/S; The default composition range is not widened here. ; Mechanical properties, delivery and hardenability require separate verification; suitability for forming a specific component requires separate confirmation.

Composition is based on Table 3 of EN10083-3:2006 in the official English text of DIN EN10083-3:2007-01, heat analysis wt%. ; Note a: Elements not listed shall not be intentionally added without the purchaser's consent, except for additions needed to finish steelmaking and to enable boron to act on hardenability.; Unspecified values shall not be treated as zero. ; Note b: Small deviations are permitted where hardenability or quenched-and-tempered mechanical-property requirements apply, except for C/P/S; permitted deviations for other elements must not exceed Table 4.; Default heat analysis range shall not be expanded. ; For non-boron steels in this standard, Note c permits steel with improved machinability to be supplied on request: sulfur approximately 0.10%, with the Mn upper limit permitted to increase by an absolute 0.15%.; Approximate values are not default hard upper limits and must be determined by specific inquiry/order; they shall not be automatically mixed with ordinary grades. ; This standard covers alloy steels for quenching and tempering. Suitability for cold heading, wire-rod supply, annealing, surface and dimensions require separate confirmation; do not automatically add products..

EN10269:2013 Table 1, section on steels for quenching and tempering; official BS adoption in English, PDF17 and footnotes PDF19; heat analysis wt%.. ; The Al column is total aluminum; For ≥.020 without a specified upper limit, only the lower limit is retained; no upper limit shall be created. ; Note b sulfur agreement applies only to grades with Note b; 27NiCrMoV15-6 magnetic properties Note c carbon upper limit .28 selected separately. ; Elements not listed shall not be intentionally added without the consent of the purchaser, except additions needed to finish steelmaking; Blank does not represent zero. ; Product analysis deviation, mechanical properties, heat treatment, and cold-heading supply suitability shall be verified separately, and not automatically added to the product center.

Table 2 cast analysis, mass fraction wt%; Si is an upper limit and unspecified elements are not filled with zero. P/S requirements for the C, Ck and Cm series remain separate; S 0.020–0.035% in S-containing grades is a two-sided range. Note 1: unlisted elements may not be intentionally added without purchaser consent, except to complete melting; no fixed residual values are inferred. Table 3 contains permissible product-analysis deviations, not added to cast limits; applicable sizes and positive/negative directions are checked separately. Heat-treatment condition, hardenability and size-dependent properties require separate verification. The standard includes hot-rolled wire rod; chemistry alone is no cold-heading supply commitment. Note 2: small composition deviations, excluding P/S, may be agreed when ordering restricted hardenability bands or quenched-and-tempered/normalized properties, but may not exceed Table 3. These data retain the Table 2 baseline without automatic relaxation. Light-typeface grades in note 4 are for special applications only. Note 5 permits separate ordering of Pb 0.15–0.30% only for the marked C-series grades; not added to ordinary base compositions. Original material number 1.6582; not marked for special application under note 4.

The cover of NF EN 10269:1999 explicitly adopts EN 10269:1999; Preserve the correspondence between the French adoption version and the European version; do not label as other countries or new editions. ; Table 1 gives heat-analysis mass percentages; Single values in P and S columns are upper limits; other single values are parsed according to the inequality signs in the original table; Unspecified elements shall not be filled as zero. ; Applies to billets, bars and wire rod of steels and nickel alloys for fasteners with specified high- or low-temperature properties.; Cold heading and actual supply must be verified in conjunction with delivery condition, dimensions, and process. ; Table 1 Footnote 1: Elements not listed in the table shall not be intentionally added without the buyer's consent (except additions needed to finish steelmaking); Elements that affect properties must be prevented from being introduced via scrap steel, etc.. ; This record only verifies the heat analysis composition in Table 1; product analysis tolerances in Table 2 shall not be automatically added to the heat limits.

Based on the original Table 1 and footnotes of EN10250-3:1999 as recorded in BS EN10250-3:2000, heat analysis mass fraction is in wt%.. ; This standard covers alloy special-steel open-die forgings, forged bars and ring-rolled products after pre-forging, supplied in the quenched-and-tempered condition.; This does not automatically establish a supply standard for cold-heading wire.. ; Table 1 Note 1 allows the manufacturer to add Al, Ti, V, Nb individually or in combination to control grain size.; No new numerical ranges are provided; values cannot be filled as zero or have upper limits arbitrarily determined.. Elements not listed in Table 1/2 shall not be intentionally added without the consent of the purchaser (except additions needed to finish steelmaking).. ; 3.1 requires the heat analysis composition to be in accordance with Table 1 and references A.7/A.8 of EN10250-1.; Clause 3.2: Apply product-analysis tolerances separately under Table 2 and Clause 9.2 of EN10250-1; do not directly expand the default heat-analysis range.. ; Currently, only chemical compositions, grade/steel number correspondences, and related range footnotes are confirmed.; It is not declared that all mechanical properties and the referenced Part 1 have been verified..
