Inconel 625 and steel P355NH were bonded by explosive welding in this study. Explosively welded bimetal clad-plate was subjected to the two separated post-weld heat treatment processes:stress 718 - National Specialty AlloysNACE can be achieved through heat treating the AMS material but it is extremely complicated and not recommended. It is produced satisfactorily at the mill in a group of its own, as the chemical composition is slightly different than the AMS grades. Although this composition is special, the material is still recognized as UNS N07718.
Alloy 718 UNS N07718 It combines corrosion resistance and high strength with outstanding weldability including resistance to post weld cracking. The alloy has excellent creep-rupture strength at temperatures to 1300(700). Strength is largely dependent on the precipit prime phase during heat treatment. Characters. Good Effect of post-weld heat treatment on microstructure Aug 15, 2018 · The effects of electron beam welding and subsequent post-weld heat treatment at different temperatures on the microstructure evolution and pitting corrosion resistance of duplex stainless steel were investigated. The as-welded joint exhibited poor pitting corrosion resistance, and pitting preferentially occurred at the ferrite grain in the weld.

Two heat treatments are generally utilized for Alloy 718. Solution anneal at 1700-1850°F followed by rapid cooling, usually in water, plus precipitation hardening at 1325°F for 8hours, furnace cool to 1150°F, hold at 1150°F for a total aging time of 18 hours, followed by air cooling. Inconel 718, UNS N07718 Applications, Alloy 718 Heat TreatmentInconel® 718 (Alloy 718), UNS N07718,Alloy 718 is an age hardenable nickel-chromium alloy having high creep-rupture strength at high temperatures to about 1300°F (700°C). The age-hardenable alloy can be readily fabricated into complex parts. Its welding characteristics, especially its resistance to postweld cracking, are outstanding. Nickel Alloy 718 / Inconel 718 (UNS N07718)- Aircraft Alloy 718 (UNS N07718, W Nr 2.4668) is an austenitic nickel-based superalloy. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. Alloy 718 is used in applications that require high strength such as parts for jet engines and high speed airframe parts such as wheels, buckets, spacers and high temperature bolts

Good welding performance. Nickel Alloy Inconel 718 Pipes And Fittings metallographic structure:718 alloy is austenitic structure, and the -phase formed by precipitation hardening has excellent mechanical properties, and the phase generated at the grain boundary during the heat treatment PWHT of chromium-nickel austenitic stainless steels - TWIMost austenitic stainless steel weldments do not require postweld heat treatment. For those that do, the heat treatment temperature should reflect the particular concern that is being addressed. The necessity for any type of heat treatment of austenitic chromium-nickel steel weldments depends largely on the service conditions encountered.
