Its recorded composition includes C 0.3–0.4%, Cr 0.7–1.1%, Mn 0.5–0.8%, Ni 2.75–3.75% and Mo 0.25–0.4%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=4eb599b7-2017-4e5f-8268-a32e20004a18&designation=1faed5e0-664c-42a5-8d3a-869a836457ce "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/34khn3ma.pdf "Datasheet as PDF") ## Chemical composition 8 elements on file · weight % What this alloy is Fe Ni Cr Mn Iron — the balance, never listed by a standard — 94.2 % Ni — 3.3 % Cr — 0.9 % Mn — 0.7 % Traces & impurities · 1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.3–0.4 | | Si | 0.17–0.37 | | Mn | 0.5–0.8 | | P | ≤ 0.03 | | S | ≤ 0.035 | | Cr | 0.7–1.1 | | Mo | 0.25–0.4 | | Ni | 2.75–3.75 | 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 | 0.3 - 0.4 | 0.300 | 0.400 | Range | | Si | 0.17 - 0.37 | 0.170 | 0.370 | Range | | P | max 0.03 | — | 0.030 | Max | | S | max 0.035 | — | 0.035 | Max | | Cr | 0.7 - 1.1 | 0.700 | 1.100 | Range | | Mn | 0.5 - 0.8 | 0.500 | 0.800 | Range | | Ni | 2.75 - 3.75 | 2.750 | 3.750 | Range | | Mo | 0.25 - 0.4 | 0.250 | 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?
