Its recorded composition includes C 0.2–0.3%, Al 1–1.6%, Cr 1.2–1.8%, Mn 0.5–0.8% and Ni 3–4%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=bd55ad45-78db-4fbc-bd62-1c3b0fe7e93e&designation=cd7cf30a-410f-4d01-84ec-f99ba894b9c8 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/2crni3moal.pdf "Datasheet as PDF") ## Chemical composition 10 elements on file · weight % What this alloy is Fe Ni Cr Al Iron — the balance, never listed by a standard — 91.9 % Ni — 3.5 % Cr — 1.5 % Al — 1.3 % Traces & impurities · 1.8 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.2–0.3 | | Si | 0.2–0.5 | | Mn | 0.5–0.8 | | P | ≤ 0.025 | | S | ≤ 0.02 | | Cr | 1.2–1.8 | | Mo | 0.2–0.4 | | Ni | 3–4 | | Cu | ≤ 0.25 | | Al | 1–1.6 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Copper Aluminium 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 | 0.2-0.3 | 0.200 | 0.300 | Range | | Al | 1-1.6 | 1.000 | 1.600 | Range | | Si | 0.2-0.5 | 0.200 | 0.500 | Range | | P | ≤0.025 | — | 0.025 | Max | | S | ≤0.02 | — | 0.020 | Max | | Cr | 1.2-1.8 | 1.200 | 1.800 | Range | | Mn | 0.5-0.8 | 0.500 | 0.800 | Range | | Ni | 3-4 | 3.000 | 4.000 | Range | | Cu | ≤0.25 | — | 0.250 | Max | | Mo | 0.2-0.4 | 0.200 | 0.400 | 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 This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here. ## 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?
