Its recorded composition includes C 1.12–1.25%, V 0.8–1.1%, Cr 3.5–4%, Mo 0.8–1.2% and W 1.9–2.6%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include HB ≤ 269. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=51e3adc1-2c98-46b4-accc-0f89ce3d71e5&designation=9f678624-dfab-41de-adcc-3297c339ff0e "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/cr4w2mov.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Cr W C Iron — the balance, never listed by a standard — 89.9 % Cr — 3.8 % W — 2.3 % C — 1.2 % Traces & impurities · 3 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 1.12–1.25 — Unusual | | Si | 0.4–0.7 | | Mn | ≤ 0.4 | | P | ≤ 0.03 | | S | ≤ 0.02 | | Cr | 3.5–4 | | Mo | 0.8–1.2 | | V | 0.8–1.1 | | W | 1.9–2.6 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Vanadium Tungsten 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 | 1.12-1.25 | 1.120 | 1.250 | Range | | Si | 0.4-0.7 | 0.400 | 0.700 | Range | | P | ≤0.03 | — | 0.030 | Max | | S | ≤0.02 | — | 0.020 | Max | | V | 0.8-1.1 | 0.800 | 1.100 | Range | | Cr | 3.5-4 | 3.500 | 4.000 | Range | | Mn | ≤0.4 | — | 0.400 | Max | | Mo | 0.8-1.2 | 0.800 | 1.200 | Range | | W | 1.9-2.6 | 1.900 | 2.600 | 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. ## 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 0 conditions · 0 values 1 further values are held for this grade under a condition the source did not name — a bound with no quantity attached. They are withheld rather than shown against a guessed condition. ## Heat treatment 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.
