Alloy 718 Description

Alloy 718 is Associate in Nursing age hardenablenickel-chromium alloy having high creep-rupture strength at high temperatures to concerning 1300°F (700°C). The age-hardenable alloy are often without delay fictitious into complicated elements. Its fastening characteristics,especially its resistance to postweld cracking, are outstanding.

Heat Treat Capabilities

Two heat treatments are usually utilised for Alloy 718


Solution normalize at 1700-1850°F followed by fast cooling, sometimes in water, and precipitation hardening at 1325°F for 8hours, chamber cool to 1150°F, hold at 1150°F for a complete aging time of eighteen hours, followed by air cooling.

Solution normalize at 1900-1950°F followed by fast cooling, sometimes in water, and precipitation hardening at 1400°F for ten hours, chamber cool to 1200°F, hold at 1200°F for a complete aging time of twenty hours, followed by air cooling.
