Its recorded composition includes C ≤ 0.08%, Si ≤ 1%, Cr 18–20%, Mn ≤ 2.5% and Ni 7.5–10.5%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm ≥ 585 N/mm² and A ≥ 30%. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=54eb4a3f-a761-4791-a45e-dbf782a273b8&designation=5031632e-04d6-447c-9018-80c9bbbbaf20 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/06cr19ni9nbn.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Cr Ni Mn Iron — the balance, never listed by a standard — 68 % Cr — 19 % Ni — 9 % Mn — 2.5 % Traces & impurities · 1.5 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.08 | | Si | ≤ 1 | | Mn | ≤ 2.5 | | P | ≤ 0.035 | | S | ≤ 0.015 | | Cr | 18–20 | | Ni | 7.5–10.5 | | Nb | ≤ 0.15 | | N | 0.15–0.3 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Nickel Niobium Nitrogen 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 | ≤0.08 | — | 0.080 | Max | | N | 0.15-0.3 | 0.150 | 0.300 | Range | | Si | ≤1 | — | 1.000 | Max | | P | ≤0.035 | — | 0.035 | Max | | S | ≤0.015 | — | 0.015 | Max | | Cr | 18-20 | 18.000 | 20.000 | Range | | Mn | ≤2.5 | — | 2.500 | Max | | Ni | 7.5-10.5 | 7.500 | 10.500 | Range | | Nb | ≤0.15 | — | 0.150 | 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 Not enough recorded composition to predict a transformation temperature for this grade — missing: 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. ## Properties by condition 0 conditions · 0 values 2 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 - Solution annealing Steel product Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
