AFNOR · France · 17 designations # E690TFP E690TFP is a designation in AFNOR for the material held under material number 1.8928, also listed as S690QL. It is a material in the category High-strength steels. We list 17 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, AFNOR, ISO, SS, ČSN and STN. - [*Material no.* **1.8928**](/materials/material-no/1.8928 "Material no.: 1.8928") - [*Category* **High-strength steels · 128 grades**](/categories/high-strength-steels "Category: High-strength steels · 128 grades") - *Designations* **17** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=b13b424b-054a-4daa-96cc-2764bcec5a78&designation=c96262d3-2405-4a02-96b9-146f850e5850 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/afnor/e690tfp.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN S690QL This grade’s own name](/materials/din-en/s690ql "DIN / EN S690QL") ## About High-strength steels High-strength steels are steels designed to carry high loads while resisting deformation. They are used for load-bearing structures, vehicles and machinery where strength, durability and reduced material weight are important. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 17 designations · 8 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures computed from composition · °C Predicted Ae3 792 °C Predicted Ae1 723 °C Predicted Acm 475 °C Predicted Bs 456 °C These four temperatures are a CALCULATION from this grade's own composition, using the published Li, Niebuhr, Meekisho & Atteridge (1998) model — never a measurement, and computed from the UPPER BOUND of each element's specified range, not a mid-range figure. Where this grade also has a measured transformation point (Ac1, Ac3, Ar1, Ar3) on file, it is shown separately, in Physical & mechanical properties, and is never replaced by the predicted figures here — Ae (predicted, equilibrium) and Ac/Ar (measured, on heating or cooling) are different physical quantities and can differ by tens of degrees; a mismatch between the two is not an error in either. ## Physical & mechanical properties Density 7,85 g/cm³ Exact An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Properties by condition 1 conditions · 6 values By thickness**no delivery state stated** source `steelnumber` | Thickness mm | ReH N/mm² | Rm N/mm² | |---|---|---| | 3 – 50 | 690 | 770 – 940 | | 50 – 100 | 650 | 760 – 930 | | 100 – 150 | 630 | 710 – 900 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.8, a shared category, and a published range for Ni / Mn that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
