UNE · Spain · 54 designations # F.3110 F.3110 is a designation in UNE for the material held under material number 1.4000, also listed as X6Cr13. It is a material in the category Stainless steels. We list 54 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, BS, AFNOR, UNE, SAE AMS, JIS, GB, GOST, UNI, SS, ČSN, PN, STN and SRPS. - [*Material no.* **1.4000**](/materials/material-no/1.4000 "Material no.: 1.4000") - [*Category* **Stainless steels · 468 grades**](/categories/stainless-steels "Category: Stainless steels · 468 grades") - *Designations* **54** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=d7ae7783-9d21-4ea6-8921-63c398e18b8b&designation=7870e670-9540-48de-8582-c4188fe2f3e1 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/une/f-3110.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X6Cr13 This grade’s own name](/materials/din-en/x6cr13 "DIN / EN X6Cr13") - [UNS S40300 This grade’s own name](/materials/uns/s40300 "UNS S40300") - [AISI / SAE 403 This grade’s own name · 6 grades on that route](/materials/aisi-sae/403 "AISI / SAE 403") ## 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 54 designations · 17 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Temper brittleness susceptible As published: predisposed 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.

They are withheld rather than shown against a guessed condition. 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. ## 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 / Si 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.
