Its recorded composition includes C ≤ 0.01%, Si ≤ 0.4%, Cr 25–27.5%, Mn ≤ 0.4% and Mo 0.75–1.5%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c976882e-6783-46fd-a893-f9b5a4f7f3d8&designation=ba160e47-2438-4cf4-9772-1acafacc84de "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/008cr27mo.pdf "Datasheet as PDF") ## Chemical composition 8 elements on file · weight % What this alloy is Fe Cr Mo Si Iron — the balance, never listed by a standard — 71.8 % Cr — 26.3 % Mo — 1.1 % Si — 0.4 % Traces & impurities · 0.5 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.01 | | Si | ≤ 0.4 | | Mn | ≤ 0.4 | | P | ≤ 0.03 | | S | ≤ 0.02 | | Cr | 25–27.5 — Unusual | | Mo | 0.75–1.5 | | N | ≤ 0.015 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nitrogen 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 | ≤0.01 | — | 0.010 | Max | | N | ≤0.015 | — | 0.015 | Max | | Si | ≤0.4 | — | 0.400 | Max | | P | ≤0.03 | — | 0.030 | Max | | S | ≤0.02 | — | 0.020 | Max | | Cr | 25-27.5 | 25.000 | 27.500 | Range | | Mn | ≤0.4 | — | 0.400 | Max | | Mo | 0.75-1.5 | 0.750 | 1.500 | 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. ## Looking for this grade under another name? Search the catalogue by designation, material number or composition — every name on this page is itself a way in.
