Its recorded composition includes C ≤ 0.15%, Cr 4–6%, Mn ≤ 0.6%, Ni ≤ 0.6% and Mo 0.45–0.6%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm 390–590 N/mm², Re ≥ 195 N/mm² and A ≥ 22%. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=d4546bb0-992c-4977-b3d9-607177105355&designation=717b90ba-d065-41c6-95c2-97270d901d8a "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/1cr5mo.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Cr Mn Ni Iron — the balance, never listed by a standard — 92.4 % Cr — 5 % Mn — 0.6 % Ni — 0.6 % Traces & impurities · 1.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.15 | | Si | ≤ 0.5 | | Mn | ≤ 0.6 | | P | ≤ 0.03 | | S | ≤ 0.03 | | Cr | 4–6 | | Mo | 0.45–0.6 | | Ni | ≤ 0.6 | | Cu | ≤ 0.2 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Copper 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 | ≤0.15 | — | 0.150 | Max | | Si | ≤0.5 | — | 0.500 | Max | | P | ≤0.03 | — | 0.030 | Max | | S | ≤0.03 | — | 0.030 | Max | | Cr | 4-6 | 4.000 | 6.000 | Range | | Mn | ≤0.6 | — | 0.600 | Max | | Ni | ≤0.6 | — | 0.600 | Max | | Cu | ≤0.2 | — | 0.200 | Max | | Mo | 0.45-0.6 | 0.450 | 0.600 | 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. ## Properties by condition 0 conditions · 0 values 3 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 Supply condition - Annealing Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
