33SIMNB7-3
1 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Carbon-equivalent reference
Manufacturer typical single values are composition references only; no range estimate is made. They are neither standard guarantees nor measured heat results; Formula applicability requires review against the intended use and process.
Composition
| Element | Composition requirement |
|---|---|
| C | Typical/nominal value 0.33 (not a guaranteed range) |
| Si | Typical/nominal value 1.7 (not a guaranteed range) |
| Mn | Typical/nominal value 0.9 (not a guaranteed range) |
Applicability and limitations
Ovako 2024 product catalogue PDF, page 42. Manufacturer Typical analysis typical values are composition references only. Units are not explicitly stated in the original header and are interpreted as mass fraction % from the manufacturer's documentation. These are neither standard-guaranteed values nor measured heat-analysis results. They are excluded from limit-based reverse lookup and carbon-equivalent calculations. Blank entries, and Other given only as an element name, are not assigned 0. Manufacturer code: SB33S17B.
Conditional requirement
- Footnote
- Units
- Source conditions
- The original table header does not state units explicitly; interpreted as mass fraction % using the manufacturer’s official chemistry information. This table does not itself print wt%.
- Footnote
- Typical analysis
- Source conditions
- All values are manufacturer’s typical single values, not limits or measured heat analysis; not used for limit-based reverse search or standard-range carbon equivalent.
- Footnote
- Grade designation
- Source conditions
- An asterisk after the original grade indicates a non-official EN standard designation, named only according to EN10027. This does not complete verification of the cited standard originals or editions.
