Its recorded composition includes C 0.26–0.35%, Si ≤ 1%, Cr 12–14%, Mn ≤ 1.25% and Ni ≤ 0.6%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c70e2883-ff22-4519-b185-4cac042114bc&designation=dd062c71-9dc6-4f53-9bb9-75b87d609e13 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/y30cr13.pdf "Datasheet as PDF") ## Chemical composition 8 elements on file · weight % What this alloy is Fe Cr Mn Si Iron — the balance, never listed by a standard — 83 % Cr — 13 % Mn — 1.3 % Si — 1 % Traces & impurities · 1.7 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.26–0.35 | | Si | ≤ 1 | | Mn | ≤ 1.25 | | P | ≤ 0.06 | | S | ≥ 0.15 — Unusual | | Cr | 12–14 | | Mo | ≤ 0.6 | | Ni | ≤ 0.6 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel 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 | 0.26-0.35 | 0.260 | 0.350 | Range | | Si | ≤1 | — | 1.000 | Max | | P | ≤0.06 | — | 0.060 | Max | | S | ≥0.15 | 0.150 | — | Min | | Cr | 12-14 | 12.000 | 14.000 | Range | | Mn | ≤1.25 | — | 1.250 | Max | | Ni | ≤0.6 | — | 0.600 | Max | | Mo | ≤0.6 | — | 0.600 | Max | 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? Search the catalogue by designation, material number or composition — every name on this page is itself a way in.
