They are characterised by hot hardness, wear resistance, toughness and resistance to thermal fatigue, making them suitable for dies, moulds, punches and other forging, extrusion and die-casting tools. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 31 designations · 16 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Chemical composition 9 elements on file · weight % What this alloy is Fe Ni Cr Mn Iron — the balance, never listed by a standard — 95.2 % Ni — 1.7 % Cr — 1 % Mn — 0.8 % Traces & impurities · 1.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.5–0.6 | | Si | 0.1–0.4 | | Mn | 0.6–0.9 | | P | 0.03 | | S | 0.03 | | Cr | 0.8–1.2 | | Mo | 0.35–0.55 | | Ni | 1.5–1.8 | | V | 0.05–0.15 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Vanadium 0.01 % 0.1 % 1 % 10 % 100 % The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other. | Element | As published source text, verbatim | Min% by weight | Max% by weight | Bound | |---|---|---|---|---| | C | 0,50-0,60 | 0.500 | 0.600 | Range | | Si | 0,10-0,40 | 0.100 | 0.400 | Range | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,03 | 0.030 | 0.030 | Exact | | V | 0,05-0,15 | 0.050 | 0.150 | Range | | Cr | 0,80-1,20 | 0.800 | 1.200 | Range | | Mn | 0,60-0,90 | 0.600 | 0.900 | Range | | Ni | 1,50-1,80 | 1.500 | 1.800 | Range | | Mo | 0,35-0,55 | 0.350 | 0.550 | Range | The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures computed from composition · °C Predicted Ae3 718 °C Predicted Ae1 721 °C Predicted Acm 716 °C Predicted Bs 480 °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 Transformation point Ac1 730 °C Exact Transformation point Ac3 780 °C Exact · Ac3(Acm) Transformation point Ar3 640 °C Exact · Ar3(Arcm) Transformation point Ar1 610 °C Exact Weldability not suitable for welding As published: is not used. Flake sensitivity susceptible As published: 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 5 conditions · 21 values By delivery state**no delivery state stated** source `steeljis` | Delivery state | HB | HRC | |---|---|---| | Annealed | 248 | — | | Quenched and tempered | — | 42 | By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 248 | By dimension**Quenching 850°C, oil, Drawing 460 - 520°C** source `splav` | Dimension mm | Rm N/mm² | Re N/mm² | A5% | Z% | KCU kJ/m² | |---|---|---|---|---|---| | 100 - 200 | 1570 | 1420 | 9 | 35 | 340 | By delivery state**no delivery state stated** source `splav` | Delivery state | HB | |---|---| | (annealing) , GOST 5950-2000 | 241 | At temperature**no delivery state stated** source `splav` | Temperature °C | Thermal expansion coefficient 10^-6/K | Thermal conductivity W/(m·K) | Electrical resistivity nΩ·m | |---|---|---|---| | 100 | — | 38 | 300 | | 200 | 12.6 | 40 | 250 | | 300 | — | 42 | 200 | | 400 | — | 42 | 160 | | 500 | — | 44 | — | | 600 | 14.2 | 46 | — | 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 1.2, a shared category, and a published range for Ni / Cr 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.
