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.
Verification notes
Original German Table 3 and its footnotes checkedJominy end-quench hardenability (conditional requirements)
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.
