Post Views: 8

1. Introduce

– Age-hardenable Ni-based superalloy with excellent strength characteristics even at temperatures down to 980°C

– Has useful strength at temperatures from 760 to 870°C

– Used in stressed environments at temperatures above 800°C

– Good oxidation resistance in gas turbine engine atmospheres up to 870°C

– Good resistance to high temperature corrosion and sulfidation at 982°C

– UNS N07001

* UNS

Abbreviation of Unified Numbering Systems for Metals and Alloys
Unified numbering system for metals and alloys
A representative number that is compatible with metals and alloys defined in many material-related codes such as ASTM, AISI, ASME, AWS, etc.

* N : Nickel and nickel alloys

* UNS N07001 : 07XXX : Chromium (Precipitation-hardenable alloy)
