Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: Mo. ## Physical & mechanical properties 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 3 conditions · 34 values By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | A5% | |---|---|---| | Sheet cold-rolled | 600 | 40 | By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | Re N/mm² | A5% | Z% | KCU kJ/m² | |---|---|---|---|---|---| | Bar, GOST 5949-75 | 880 | 590 | 10 | 15 | 290 | At temperature**no delivery state stated** source `splav` | Temperature °C | Density g/cm³ | Elastic modulus GPa | Thermal expansion coefficient 10^-6/K | Thermal conductivity W/(m·K) | |---|---|---|---|---| | 20 | 7.9 | 160 | — | 15.2 | | 100 | — | — | 15.9 | 16.3 | | 200 | — | — | 17.4 | 17.5 | | 300 | — | — | 18.8 | 18.8 | | 400 | — | 140 | 19.9 | 20.5 | | 500 | — | 135 | 20.3 | 22.6 | | 600 | — | 132 | 21.1 | 23.8 | | 700 | — | 115 | 21.8 | 25.1 | | 800 | — | 113 | 21.6 | 26.8 | | 900 | — | 90 | 21.3 | 28.5 | 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?
