Material number · Europe · 15 designations # 1.4041 1.4041 is the material number of the grade also listed as X85Cr17. It is a material in the category Stainless steels. We list 15 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, SAE AMS, JIS and GB. - ***Material no.* **1.4041**** - [*Category* **Stainless steels · 468 grades**](/categories/stainless-steels "Category: Stainless steels · 468 grades") - *Designations* **15** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=2246bfc5-1c5c-4159-9a8c-9e2354d5c1f7 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.4041.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X85Cr17 This grade’s own name](/materials/din-en/x85cr17 "DIN / EN X85Cr17") - [UNS S44003 This grade’s own name · 6 grades on that route](/materials/uns/s44003 "UNS S44003") - [AISI / SAE 440B This grade’s own name · 6 grades on that route](/materials/aisi-sae/440b "AISI / SAE 440B") ## About Stainless steels Stainless steels are corrosion-resistant alloy steels whose chromium content promotes a protective passive surface film. They are used for equipment, structures and components exposed to moisture, chemicals or hygienic service, with different alloy compositions selected for corrosion resistance, strength, formability or weldability. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 15 designations · 7 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 Cr Si Mn Iron — the balance, never listed by a standard — 78.7 % Cr — 17 % Si — 1 % Mn — 1 % Traces & impurities · 2.3 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.75–0.95 — Unusual | | Si | ≤ 1 | | Mn | ≤ 1 | | P | 0.04 | | S | 0.03 | | Cr | 16–18 | | Mo | ≤ 0.75 | | Ni | 0.6 | 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 | 0,75-0,95 | 0.750 | 0.950 | Range | | Si | ≤1,00 | — | 1.000 | Max | | P | 0,04 | 0.040 | 0.040 | Exact | | S | 0,03 | 0.030 | 0.030 | Exact | | Cr | 16,0-18,0 | 16.000 | 18.000 | Range | | Mn | ≤1,00 | — | 1.000 | Max | | Ni | 0,6 | 0.600 | 0.600 | Exact | | Mo | ≤0,75 | — | 0.750 | 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 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 Density 7,85 g/cm³ Exact Elastic modulus 200 GPa Exact Thermal expansion coefficient 10.2 10^-6/K Exact Thermal conductivity 24.2（100°C） W/(m·K) Range Specific heat capacity 0.46 J/(kg·K) Exact Electrical resistivity 0.6 nΩ·m Exact 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. ## Heat treatment Supply condition - Annealing Steel bar d≤75 - Annealing - Quenching and Tempering Test specimen d≤75 Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
