INCONEL® alloy 718 (UNS N07718/W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F. Typical composition limits are shown in Table 1.
The age-hardenable alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its resistance to postweld cracking, are outstanding.
Workability of inconel 718
Hot Working
Hot-working is carried out using a 2050°F (1121°C) maximum furnace temperature. Hot-cold working in the range
1700/1850°F (927/1010°C) will improve the strength of the forging if the service temperature is below about 1100°F (593°C).
Prolonged soaking at the forging temperature is not desirable. The material should be given uniform reductions to avoid the formation of
duplex grain structures.Machining The alloy can be readily machined in either the annealed or the age-hardened condition. The age-hardened
condition gives better chip action on chip breaker tools and produces a better finish. The annealed condition will give a slightly longer tool life.
Welding Alloy 718 can be welded in either the annealed or the age condition. Welding in the aged condition will cause the formation of a softened heat-affected zone.
