Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Chemical composition 8 elements on file · weight % What this alloy is Fe Mn C Si Iron — the balance, never listed by a standard — 97.3 % Mn — 1 % C — 0.9 % Si — 0.4 % Traces & impurities · 0.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.83–0.9 | | Si | 0.25–0.6 | | Mn | 0.75–1.15 | | P | ≤ 0.025 | | S | ≤ 0.025 | | Cr | ≤ 0.3 | | V | 0.03–0.15 | | Al | ≤ 0.01 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Vanadium 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 | 0.83 - 0.9 | 0.830 | 0.900 | Range | | Al | max 0.01 | — | 0.010 | Max | | Si | 0.25 - 0.6 | 0.250 | 0.600 | Range | | P | max 0.025 | — | 0.025 | Max | | S | max 0.025 | — | 0.025 | Max | | V | 0.03 - 0.15 | 0.030 | 0.150 | Range | | Cr | max 0.3 | — | 0.300 | Max | | Mn | 0.75 - 1.15 | 0.750 | 1.150 | 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, Mo. ## 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?
