N07725 is the Unified Numbering System (UNS) designation for a nickel-based alloy most commonly known as Inconel 725. The UNS system was created by a number of trade groups working together in the 1970’s, to reduce confusion from the same alloy being called different things or vice-versa. Each metal is indicated by a letter followed by five numbers, where the letter indicates the family of metals i.e. N for nickel-based alloys.
Alloy 725 (Inconel 725, UNS N07725) is practically identical to Alloy 625 (Inconel 625, UNS N06625, 2.4856) in terms of composition, and therefore provide very similar corrosion resistance and physical properties. However, Alloy 725 provides significantly higher levels of strength as it benefits from precipitation strengthening. Small additions are made to its composition, which allow the formation of microscopic precipitates when the alloy is subjected to an extended heat treatment process. These fine precipitates increase the yield strength by 2x. Inconel is a trademark of Special Metal Inc, covering a family of nickel-chromium alloys.
Langley Alloys stocks Alloy 725 from 1″ (25.4mm) to 4″ (101.6mm) diameter.
