Applicability and limitations
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..
Verification notes
Official English source cover, all 28 grades in Table 3 and notes a–c visually checked.Permitted product-analysis deviations (must not be added to heat-analysis limits)
DIN EN10083-3:2007-01 (adopting EN10083-3:2006) · Table 4 and notes a/b, 7.1.2.2; Product analysis specified at ordering follows A.5 · PDF pages 11, 19, 55 · mass fraction wt%; Deviations are expressed in percentage points of mass percentage
The complete standard tolerance table applies only to elements specified in the original table for this grade and to the corresponding content/sulfur-range conditions; it does not widen heat-analysis composition, carbon equivalent or reverse-search ranges.
| Element | Specified maximum heat-analysis content, wt% | Lower deviation, percentage points | Upper deviation, percentage points | Applicable conditions |
|---|---|---|---|---|
| C | ≤0.55 | -0.02 | +0.02 | Select the cast-analysis maximum-content band specified in the original table |
| Si | ≤0.40 | The original table does not state a negative deviation | +0.03 | Select the cast-analysis maximum-content band specified in the original table |
| Mn | ≤1.00 | -0.04 | +0.04 | Select the cast-analysis maximum-content band specified in the original table |
| Mn | >1.00≤1.70 | -0.05 | +0.05 | Select the cast-analysis maximum-content band specified in the original table |
| P | ≤0.025 | The original table does not state a negative deviation | +0.005 | Select the cast-analysis maximum-content band specified in the original table |
| S | ≤0.040 | The original table does not state a negative deviation | +0.005 | Only the sulfur upper limit is specified; Note b’s full 0.020–0.040% range is not applied. |
| Cr | ≤2.00 | -0.05 | +0.05 | Select the cast-analysis maximum-content band specified in the original table |
| Cr | >2.00≤2.20 | -0.1 | +0.1 | Select the cast-analysis maximum-content band specified in the original table |
| Mo | ≤0.30 | -0.03 | +0.03 | Select the cast-analysis maximum-content band specified in the original table |
| Mo | >0.30≤0.60 | -0.04 | +0.04 | Select the cast-analysis maximum-content band specified in the original table |
| Ni | ≤2.00 | -0.05 | +0.05 | Select the cast-analysis maximum-content band specified in the original table |
| Ni | >2.00≤4.3 | -0.07 | +0.07 | Select the cast-analysis maximum-content band specified in the original table |
| V | ≤0.25 | -0.02 | +0.02 | Select the cast-analysis maximum-content band specified in the original table |
| B | ≤0.0050 | -0.0003 | +0.0003 | Select the cast-analysis maximum-content band specified in the original table |
| S | ≤0.040 | -0.005 | +0.005 | Only when Table 3 heat analysis explicitly specifies the full S range of 0.020–0.040% (Table 4, Note b). |
- Table 4 Note a: For a same-heat tolerance, deviation is permitted in only one direction—above the upper limit or below the lower limit—not both.
- S product-analysis tolerance is usually only +0.005. Note b permits ±0.005 only for steels whose heat analysis explicitly specifies the full 0.020–0.040% range; do not apply Note b based only on the maximum S value.
- Clause 7.1.2.2 requires product analysis to be specified at ordering and refers to A.5; without a heat-lot test report, this table does not prove that the actual product conforms.
- A.5: one product analysis per heat, limited to elements specified for the grade; sampling per EN ISO 14284. For disputes, reference methods are the European standards listed in CR 10261.
This is a complete standard deviation table and does not imply that every element for this grade is specified; Elements not listed are not added on the basis of this table. Symmetric deviation for the same heat is permitted in only one direction, either upward or downward; Asymmetric deviation for Pb is only found in the Pb row of EN10087 and cannot be applied to other standards where Pb is not listed. Do not automatically expand heat analysis composition, carbon equivalent, or reverse-lookup ranges.
