Its recorded composition includes C ≤ 0.05%, Al 0.9–1.35%, Cr 12.3–13.25%, Ni 7.5–8.5% and Mo 2–2.5%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=eabfe130-4faa-43e4-8b94-ee26202c7910&designation=7ff23705-173e-47db-aa05-76e5c065e188 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/04cr13ni8mo2al.pdf "Datasheet as PDF") ## Chemical composition 10 elements on file · weight % What this alloy is Fe Cr Ni Mo Iron — the balance, never listed by a standard — 75.5 % Cr — 12.8 % Ni — 8 % Mo — 2.3 % Traces & impurities · 1.5 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.05 | | Si | ≤ 0.1 | | Mn | ≤ 0.2 | | P | ≤ 0.01 | | S | ≤ 0.008 | | Cr | 12.3–13.25 | | Mo | 2–2.5 | | Ni | 7.5–8.5 | | Al | 0.9–1.35 | | N | ≤ 0.01 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Aluminium 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 | ≤0.05 | — | 0.050 | Max | | N | ≤0.01 | — | 0.010 | Max | | Al | 0.9-1.35 | 0.900 | 1.350 | Range | | Si | ≤0.1 | — | 0.100 | Max | | P | ≤0.01 | — | 0.010 | Max | | S | ≤0.008 | — | 0.008 | Max | | Cr | 12.3-13.25 | 12.300 | 13.250 | Range | | Mn | ≤0.2 | — | 0.200 | Max | | Ni | 7.5-8.5 | 7.500 | 8.500 | Range | | Mo | 2-2.5 | 2.000 | 2.500 | 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 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?
