GB · China · 14 designations # S23043 S23043 is a designation in GB for the material held under material number 1.4362, also listed as X2CrNiN23-4. It is a material in the category Stainless steels. We list 14 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, AFNOR, GB, GOST and SS. - [*Material no.* **1.4362**](/materials/material-no/1.4362 "Material no.: 1.4362") - [*Category* **Stainless steels · 468 grades**](/categories/stainless-steels "Category: Stainless steels · 468 grades") - *Designations* **14** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c483c86e-4dbc-4e95-8363-a0f70673bfe3&designation=d7947890-7b0a-4a0c-8857-0b45459131ad "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/s23043.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X2CrNiN23-4 This grade’s own name](/materials/din-en/x2crnin23-4 "DIN / EN X2CrNiN23-4") - [UNS S32304 This grade’s own name](/materials/uns/s32304 "UNS S32304") - [AFNOR Z2CN23-04AZ This grade’s own name](/materials/afnor/z2cn23-04az "AFNOR Z2CN23-04AZ") - [SS SIS 2327 This grade’s own name](/materials/ss/sis-2327 "SS SIS 2327") ## 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 14 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 10 elements on file · weight % What this alloy is Fe Cr Ni Mn Iron — the balance, never listed by a standard — 68.6 % Cr — 23 % Ni — 4.5 % Mn — 2 % Traces & impurities · 1.9 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.03 | | Si | ≤ 1 | | Mn | ≤ 2 | | P | 0.035 | | S | 0.015 | | Cr | 22–24 | | Mo | 0.1–0.6 | | Ni | 3.5–5.5 | | Cu | 0.1–0.6 | | N | 0.05–0.2 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Copper 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 | ≤0,030 | — | 0.030 | Max | | N | 0,05-0,20 | 0.050 | 0.200 | Range | | Si | ≤1,00 | — | 1.000 | Max | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,015 | 0.015 | 0.015 | Exact | | Cr | 22,0-24,0 | 22.000 | 24.000 | Range | | Mn | ≤2,00 | — | 2.000 | Max | | Ni | 3,50-5,50 | 3.500 | 5.500 | Range | | Cu | 0,10-0,60 | 0.100 | 0.600 | Range | | Mo | 0,10-0,60 | 0.100 | 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 Density 7,9 g/cm³ 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. ## Properties by condition 3 conditions · 5 values By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 260 | By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | Re N/mm² | A5% | |---|---|---|---| | Sheet trick, GOST 7350-77 | 590 | 345 | 25 | By delivery state**Solution annealed** source `steelnumber` | Delivery state | HB | |---|---| | Solution annealed | 290 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## 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.

These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
