It does not mean the property is undefined for the material. ## Properties by condition 1 conditions · 2 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | HB | |---|---|---| | Casting, GOST 7769-82 | 350 | — | | GOST 7769-82 | — | 400 – 450 | 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?
