They are selected for applications requiring particular combinations of strength, hardness, toughness, wear resistance or resistance to demanding service conditions. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 33 designations · 23 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

It does not mean the property is undefined for the material. ## Properties by condition 2 conditions · 7 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | HB | |---|---|---| | Casting, GOST 1412-85 | 300 | — | | GOST 1412-85 | — | 163 – 270 | 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) | Specific heat capacity J/(kg·K) | |---|---|---|---|---|---| | 20 | 7.3 | 130 | — | 46 | — | | 100 | — | — | 10.5 | — | 525 | 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. ## Heat treatment **GB 2100-1980** Single operation - Quenching 1050–1100 °C Cooling Water Source: [www.caishuku.com](https://www.caishuku.com/detail/azhlNWIxNjA1MA__ "Source: www.caishuku.com") ## Looking for this grade under another name?
