Alliages résistants à la chaleur
UNS N06002, 2.4665, comparable to Hastelloy X Alloy
UNS N06002 is a nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance in temperatures reaching as high as 1200℃. With superior workability and weldability as well, it is excellent for use in gas turbine members as well as various heating furnace parts.
Other form we also take in, you can email us the artwork, thanks
Manque de maniabilité
We recommend using a range of 982 to 1177℃ for hot working N06002. N06002 can also be easily cold worked. Note that a greater force is required to work N06002 than standard austenitic stainless steels. Solution treatment should be applied after working to obtain favorable creep properties.
Soudabilité
Such techniques as TIG, MIG and shield metal arc welding can be used for N06002 as with standard austenitic stainless steels. Before welding, the weld surface should be cleaned off oxidizing scales as well as oil and dirt.
Traitement thermique
The recommended solution heat treatment temperature is between 1149 and 1177℃, the range stipulated in SAE AMS 5536L. Rapid cooling is required after heat treatment to prevent precipitates.
Applications
Gas turbine heat chambers; afterburner tail pipes and other components; heating furnace fans, rollers, trays, hardware, and other parts
