We list 24 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, BS, AFNOR, ISO, JIS, GB, GOST, UNI, ČSN, STN, HRN, PN and ÖNORM. - [*Material no.* **1.2842**](/materials/material-no/1.2842 "Material no.: 1.2842") - [*Category* **Tool steels for cold work · 109 grades**](/categories/tool-steels-for-cold-work "Category: Tool steels for cold work · 109 grades") - *Designations* **24** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c60833d6-9054-4989-9d42-ba235de83316&designation=2c9c1597-646e-4849-aa69-2bf5bb3485d2 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/uni/90mncrv8ku.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 90MnCrV8 This grade’s own name](/materials/din-en/90mncrv8 "DIN / EN 90MnCrV8") - [UNS T31502 This grade’s own name](/materials/uns/t31502 "UNS T31502") - [AISI / SAE O 2 This grade’s own name](/materials/aisi-sae/o-2 "AISI / SAE O 2") ## About Tool steels for cold work Cold-work tool steels are high-strength tool materials designed for shaping, cutting and forming operations carried out without significant heating of the workpiece. They are characterised by high hardness, wear resistance and the ability to retain a sharp or precise working edge, making them suitable for dies, punches, cutting tools and other tooling exposed to repeated mechanical contact. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 24 designations · 15 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 7 elements on file · weight % What this alloy is Fe Mn C Cr Iron — the balance, never listed by a standard — 96.3 % Mn — 2 % C — 0.9 % Cr — 0.4 % Traces & impurities · 0.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.85–0.95 | | Si | 0.1–0.4 | | Mn | 1.8–2.2 — Unusual | | P | 0.03 | | S | 0.03 | | Cr | 0.2–0.5 | | V | 0.05–0.2 | Carbon Silicon Manganese Phosphorus Sulfur Chromium 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 | 0,85-0,95 | 0.850 | 0.950 | 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 | 0,05-0,20 | 0.050 | 0.200 | Range | | Cr | 0,20-0,50 | 0.200 | 0.500 | Range | | Mn | 1,80-2,20 | 1.800 | 2.200 | 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 Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Mo. ## Physical & mechanical properties Density 7,85 g/cm³ Exact 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 1 conditions · 1 values By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 229 | 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 /T 1299-2025** Single operation Test specimen - Quenching 780–810 °C Cooling Oil Supply condition - Quenching Test specimen - Annealing Supply condition Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
