Allegheny Ludlum Altemp® 718 Nickel-Base Superalloy, Solution Treated Sheet and Strip, UNS N07718

 

Subcategory: Superalloy; Nickel Base

Key Words: DIN 2.4668; ASTM B-670; AMS 5596; AMS 5597

Material Notes:
Iron content above calculated as remainder.

Allegheny Ludlum Altemp 718 alloy is an austenitic nickel-base superalloy which is used in applications requiring high strength to approximately 760 degrees Celsius and oxidation resistance to approximately 982 degrees Celsius. In addition, the alloy exhibits excellent tensile and impact strength even at cryogenic temperatures. High strength at room and elevated temperatures is developed by a precipitation heat treatment at 718 degrees Celsius with cooling and a hold at 621°C.

The relatively slow response to precipitation hardening permits repair welding of the Altemp 718 alloy even in the aged condition. The Altemp 718 alloy is usually produced by a double melt practice using consumable electrode remelt procedures to provide homogeneity and extremely clean structures. Specific uses include aircraft ducting and engine plumbing.

Tensile properties below are from AMS 5596 and/or AMS 5597.
