Composition conditions
- ISO 4954:2018 Table B.2 specifies heat analysis; a single value is an upper limit, and 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.

Applicability and limitations
Ladle analysis, mass fraction wt%; the DIN EN 10084:2008-06 cover expressly identifies the German edition of EN 10084:2008; Table 3 follows that source text. Note b: minor composition deviations associated with hardenability requirements must be checked separately against Table 4 and the applicable conditions; they do not widen default ranges, and no such relaxation applies to P/S. Note c: higher S (approximately up to 0.10%) or Pb may be requested for improved machinability; in the higher-S case, the Mn upper limit may increase by 0.15 percentage points. Actual agreed values are not given; do not invent them or apply them automatically. Note d: B in this table improves toughness in the hardened case, not hardenability. Unlisted elements must not be intentionally added without purchaser approval (except as necessary during steelmaking); unspecified does not mean zero. A delivery standard for case-hardening steel does not mean all conditions are suitable for cold heading; verify mechanical properties, hardness and hardenability separately.

Viewing a selection is not contractual confirmation and does not change the ordinary grade designation or order conditions.
- HRC is hardness at a specified distance on a Jominy end-quench specimen, not bulk finished-part hardness, cold-heading acceptance, supply capability or part-performance guarantee.
- Horizontal lines preserve unspecified upper and lower limits and shall not be treated as 0; Do not automatically interpolate, extrapolate, or assess compliance at unlisted distances.
- Table 8 temperatures are austenitizing conditions for the Jominy specimen, not production heat-treatment recommendations. No temperature tolerance is given; do not add ±5°C. Table 8 Note a holding time is indicative only, not a guaranteed requirement.
- 8.2.2 permits the manufacturer to demonstrate hardenability by calculation where a suitable formula exists; the manufacturer chooses the method and, when agreed at enquiry/order, supplies sufficient information for customer review. This tool has not implemented or certified such calculations.
- If no applicable formula exists or a dispute arises, use the end-quench test in EN ISO 642 and Table 9; use Table 8 specimen quenching temperature and the C scale of EN ISO 6508-1 for hardness. The source cites ISO 642:1999 and ISO 6508-1:2005; do not update the cited years.
- Table 9: When inspection certificates and corresponding requirements of Table 1 are applicable, heat C shall be the test unit, with 1 sample per 1 test.

EN 10084:2008 · DIN EN 10084:2008-06, cover explicitly states German version of EN 10084:2008 · Table 5/Table 6/Table 8/Table 9; 7.1.2 and 8.2.2 · PDF pages 7, 10, 12, 18, 19, 22, 23
- 7.1.2: Unless otherwise agreed, Table 5 normal +H hardenability requirements apply to alloy steels in this standard; restricted +HH/+HL bands in Table 6 must be agreed at enquiry/order. Viewing a selection is not contractual confirmation and does not change the ordinary grade designation or order conditions.
- HRC is hardness at a specified distance on a Jominy end-quench specimen, not bulk finished-part hardness, cold-heading acceptance, supply capability or part-performance guarantee.
- Horizontal lines preserve unspecified upper and lower limits and shall not be treated as 0; Do not automatically interpolate, extrapolate, or assess compliance at unlisted distances.
- Table 8 temperatures are austenitizing conditions for the Jominy specimen, not production heat-treatment recommendations. No temperature tolerance is given; do not add ±5°C. Table 8 Note a holding time is indicative only, not a guaranteed requirement.
- 8.2.2 permits the manufacturer to demonstrate hardenability by calculation where a suitable formula exists; the manufacturer chooses the method and, when agreed at enquiry/order, supplies sufficient information for customer review. This tool has not implemented or certified such calculations.
- If no applicable formula exists or a dispute arises, use the end-quench test in EN ISO 642 and Table 9; use Table 8 specimen quenching temperature and the C scale of EN ISO 6508-1 for hardness. The source cites ISO 642:1999 and ISO 6508-1:2005; do not update the cited years.
- Table 9: When inspection certificates and corresponding requirements of Table 1 are applicable, heat C shall be the test unit, with 1 sample per 1 test. When dimensions do not allow for the preparation of end-quench specimens, the conditions for proving hardenability must be agreed upon; In other cases, unless otherwise agreed, the specimen preparation method shall be determined by the manufacturer.
- Table 9 sampling note b is printed “20 m”, conflicting in units with “20 mm” in note c; defer automatic interpretation of that sampling depth. Do not silently correct it or use it as a specimen-preparation instruction.
- The DIN original explicitly adopts EN10084:2008; display only according to this EN technical source; The supplementation of hardenability in this batch shall not be used to claim that the NF standard cover or other standard identities have been verified.

Applicability and limitations
Actually based on the official English text of EN 10132-2:2000; This standard covers cold-rolled narrow steel strip intended for heat treatment; it does not constitute a supply guarantee for cold-heading wire.. Table 1 is for heat analysis; Permissible deviations for finished product analysis in Table 2 are registered independently; finished product permissible deviations shall not be used to relax heat analysis. Table 1 Footnote: Elements not listed shall not be intentionally added without the buyer's consent, except additions needed to finish steelmaking; Prevent scrap or other raw materials from introducing elements that could impair properties or intended use; unlisted elements must not be assumed zero.. Values in Mechanical Table 3 are applicable only for 0.30 mm≤t<3.00 mm; Mechanical properties for thicker steel strips shall be agreed upon during inquiry and ordering and cannot be directly extrapolated. Footnote a of Table 3 requires a choice between tensile indicators and hardness; Unless otherwise specified, tensile requirements apply. This page presents the alternatives separately and does not treat both as simultaneous guaranteed requirements.. For cold-rolled +CR, agree a tensile-property interval 150 MPa wide when tensile requirements are selected, or a hardness interval 50 HV wide when hardness is selected.; The outer boundaries of this table do not automatically generate actual ordering windows. Sampling, test methods, microstructure, dimensions, inspection, and other general delivery requirements shall also be verified in conjunction with EN10132-1 and applicable agreements; composition reverse-check does not replace full-item acceptance. This part applies to cold-rolled narrow steel strips for carburizing, with a standard thickness range up to 10mm; The +CR properties of 16MnCr5/17Cr3 shall be agreed upon during ordering.
