It is a material in the category High-temperature steels. We list 26 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, BS, AFNOR, ISO, SAE AMS, JIS, GB, GOST and SS. - [*Material no.* **2.4665**](/materials/material-no/2.4665 "Material no.: 2.4665") - [*Category* **High-temperature steels · 40 grades**](/categories/high-temperature-steels "Category: High-temperature steels · 40 grades") - *Designations* **26** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=6fc4266b-ffaa-49bd-a5f4-c79f988e8450&designation=9c3bba28-bcc2-4e3e-a9a5-bf267fd291e5 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/aisi-sae/5536e.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN NiCr22Fe18Mo This grade’s own name · 2 grades on that route](/materials/din-en/nicr22fe18mo "DIN / EN NiCr22Fe18Mo") - [AISI / SAE Alloy X This grade’s own name](/materials/aisi-sae/alloy-x "AISI / SAE Alloy X") ## About High-temperature steels High-temperature steels are steels designed to retain useful strength and structural stability during exposure to elevated temperatures. Their alloying systems provide resistance to oxidation, creep and loss of mechanical properties during prolonged heating, making them suitable for furnace components, heat exchangers, boilers and other hot-service equipment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 26 designations · 12 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

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: Ni. ## Physical & mechanical properties Density 8,22 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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 2.4, a shared category, and a published range for Ni / Cr 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.
