Inconel® 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.
Applications:
Nuclear hold down spring and other components
Gas turbine components
Springs
Seal rings
Heat Treat Capabilities:
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.
--Solution anneal at 1900-1950°F followed by rapid cooling, usually in water, plus precipitation hardening at 1400°F for 10 hours, furnace cool to 1200°F, hold at 1200°F for a total aging time of 20 hours, followed by air cooling.
