SS · Sweden · 47 designations # Duplex 2324 Duplex 2324 is a designation in SS for the material held under material number 1.4460, also listed as X3CrNiMoN27-5-2. It is a material in the category Stainless steels. We list 47 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, AFNOR, UNE, JIS, GB, GOST, SS and PN. - [*Material no.* **1.4460**](/materials/material-no/1.4460 "Material no.: 1.4460") - [*Category* **Stainless steels · 468 grades**](/categories/stainless-steels "Category: Stainless steels · 468 grades") - *Designations* **47** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=d474f1ce-6587-4a67-b9cd-eb6196fe50c6&designation=0425ff3f-7003-4392-9eca-fce87a0f3da2 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/ss/duplex-2324.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X3CrNiMoN27-5-2 This grade’s own name](/materials/din-en/x3crnimon27-5-2 "DIN / EN X3CrNiMoN27-5-2") - [UNS S31200 This grade’s own name](/materials/uns/s31200 "UNS S31200") - [AISI / SAE 329 This grade’s own name · 2 grades on that route](/materials/aisi-sae/329 "AISI / SAE 329") ## 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 47 designations · 11 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.

Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.4, a shared category, and a published range for Cr / Ni that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
