Flake sensitivity not susceptible As published: not predisposed Temper brittleness not susceptible As published: not predisposed 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 2 conditions · 6 values By dimension**no delivery state stated** source `splav` | Dimension mm | Rm N/mm² | Re N/mm² | A5% | |---|---|---|---| | to 60 | 450 | 315 | 26 | By dimension**no delivery state stated** source `splav` | Dimension mm | Rm N/mm² | Re N/mm² | A5% | |---|---|---|---| | 4 | 470 | 320 | 26 | 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. ## Looking for this grade under another name?
