ISO · International · 11 designations # NiCr20Cr20Mo5Ti2Al NiCr20Cr20Mo5Ti2Al is a designation in ISO for the material held under material number 2.4650, also listed as NiCo20Cr20MoTi. It is a material in the category Nickel and cobalt alloys. We list 11 designations recorded for this grade, in the standards DIN / EN, UNS, BS, AFNOR, ISO and SAE AMS. - [*Material no.* **2.4650**](/materials/material-no/2.4650 "Material no.: 2.4650") - [*Category* **Nickel and cobalt alloys · 87 grades**](/categories/nickel-and-cobalt-alloys "Category: Nickel and cobalt alloys · 87 grades") - *Designations* **11** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=5e8d04b9-3e36-4a41-9e9c-c8ceb1372ef6&designation=9667b887-52be-459f-aa61-23739ee7cbe2 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/iso/nicr20cr20mo5ti2al.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN NiCo20Cr20MoTi This grade’s own name](/materials/din-en/nico20cr20moti "DIN / EN NiCo20Cr20MoTi") - [UNS N07263 This grade’s own name](/materials/uns/n07263 "UNS N07263") ## About Nickel and cobalt alloys Nickel and cobalt alloys are metallic materials whose properties are developed through nickel-, cobalt-, or combined alloying systems. They are characterised by strong resistance to corrosion, oxidation, wear, and loss of strength at elevated temperatures, making them suitable for turbine components, chemical-processing equipment, and other demanding high-temperature applications. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 11 designations · 6 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 7,85 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.
