Its recorded composition includes C 0.5–0.6%, Cr 0.8–1.2%, Mn 0.6–0.9%, Ni 1.5–1.8% and Mo 0.35–0.55%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include HB ≤ 255. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=2d4eaf99-3892-4502-aa53-088ed312db5d&designation=82bafc96-ff59-48f7-ae7f-b665f76cd0cb "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/5crni2mov.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Ni Cr Mn Iron — the balance, never listed by a standard — 95.2 % Ni — 1.7 % Cr — 1 % Mn — 0.8 % Traces & impurities · 1.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.5–0.6 | | Si | 0.1–0.4 | | Mn | 0.6–0.9 | | P | ≤ 0.03 | | S | ≤ 0.03 | | Cr | 0.8–1.2 | | Mo | 0.35–0.55 | | Ni | 1.5–1.8 | | V | 0.05–0.15 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Vanadium 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 | 0.5-0.6 | 0.500 | 0.600 | Range | | Si | 0.1-0.4 | 0.100 | 0.400 | Range | | P | ≤0.03 | — | 0.030 | Max | | S | ≤0.03 | — | 0.030 | Max | | V | 0.05-0.15 | 0.050 | 0.150 | Range | | Cr | 0.8-1.2 | 0.800 | 1.200 | Range | | Mn | 0.6-0.9 | 0.600 | 0.900 | Range | | Ni | 1.5-1.8 | 1.500 | 1.800 | Range | | Mo | 0.35-0.55 | 0.350 | 0.550 | 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 computed from composition · °C Predicted Ae3 718 °C Predicted Ae1 721 °C Predicted Acm 716 °C Predicted Bs 480 °C These four temperatures are a CALCULATION from this grade's own composition, using the published Li, Niebuhr, Meekisho & Atteridge (1998) model — never a measurement, and computed from the UPPER BOUND of each element's specified range, not a mid-range figure. Where this grade also has a measured transformation point (Ac1, Ac3, Ar1, Ar3) on file, it is shown separately, in Physical & mechanical properties, and is never replaced by the predicted figures here — Ae (predicted, equilibrium) and Ac/Ar (measured, on heating or cooling) are different physical quantities and can differ by tens of degrees; a mismatch between the two is not an error in either. ## 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. ## Properties by condition 0 conditions · 0 values 1 further values are held for this grade under a condition the source did not name — a bound with no quantity attached. They are withheld rather than shown against a guessed condition. ## Heat treatment **GB /T 1299-2025** Single operation Test specimen - Quenching 850–880 °C Cooling Oil Supply condition - Quenching Test specimen - Annealing Supply condition Conditions the standard permits on delivery.
