Their hot hardness and wear resistance make them suitable for cutting tools such as drills, milling cutters, taps and broaches. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Chemical composition 10 elements on file · weight % What this alloy is Fe Mo Cr Co Iron — the balance, never listed by a standard — 83.9 % Mo — 4.9 % Cr — 4 % Co — 2.5 % Traces & impurities · 4.7 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.87–0.95 | | Si | 0.3–0.6 | | Mn | 0.2–0.4 | | P | 0.03 | | S | 0.03 | | Cr | 3.5–4.5 | | Mo | 4.5–5.2 | | V | 1.1–1.5 | | W | 1.4–2 | | Co | 2.3–2.7 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Vanadium Tungsten Cobalt 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 | 0,87-0,95 | 0.870 | 0.950 | Range | | Si | 0,30-0,60 | 0.300 | 0.600 | Range | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,03 | 0.030 | 0.030 | Exact | | V | 1,10-1,50 | 1.100 | 1.500 | Range | | Cr | 3,50-4,50 | 3.500 | 4.500 | Range | | Mn | 0,20-0,40 | 0.200 | 0.400 | Range | | Co | 2,30-2,70 | 2.300 | 2.700 | Range | | Mo | 4,50-5,20 | 4.500 | 5.200 | Range | | W | 1,40-2,00 | 1.400 | 2.000 | 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 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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.3, a shared category, and a published range for Mo / 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.
