Nickel Alloys

N06625 is the Unified Numbering System (UNS) designation for a nickel-based alloy most commonly known as Inconel 625.

2.4375 is the Werkstoff number for a nickel-based alloy most commonly known as Monel K-500.

2.4668 is the Werkstoff number for a nickel-based alloy most commonly known as Inconel 718.

2.4856 is the Werkstoff number for a nickel-based alloy most commonly known as Inconel 625.

Precipitation hardening is a heat treatment process applied to various alloys to significantly increase their yield strength.

Alloy 825’s corrosion resistance in a wide range of oxidising and non-oxidising acids is far better than might have been anticipated.

Outside of aerospace, the largest single market for Alloy 718 is in assorted Oil & Gas applications.

Alloy 925 is a precipitation-hardened version of Alloy 825.

API 6A CRA is a supplement to API 6A, covering a group of high performance alloys – specifically age-hardened nickel alloys.

Alloy 825 and Alloy 925 are nearly identical in composition, but Alloy 925 is appreciably higher strength.

Alloy 625 and Alloy 725 are nearly identical in composition, but Alloy 725 is appreciably higher strength.

With such a wide range of different alloys available, it is quite possible that several may all be suitable for a given application.
