wwwwww..ssppeecciiaallmmeettaallss..ccoomm INCONEL® alloy 718 (UNS N07718/W.Nr. 2.4668) is a TTaabbllee 11 a - Limiting Chemical Composition , % high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F. Typical composition Nickel (plus Cobalt) 50.00-55.00 limits are shown in Table 1. Chromium17.00-21.00 The age-hardenable alloy can be readily fabricated, Iron Balance* even into complex parts. Its welding characteristics, Niobium (plus Tantalum)4.75-5.50 especially its resistance to postweld cracking, are Molybdenum 2.80-3.30 outstanding. Titanium0.65-1.15 The ease and economy with which INCONEL alloy 718 Aluminum 0.20-0.80 can be fabricated, combined with good tensile, fatigue, Cobalt 1.00 max. creep, and rupture strength, have resulted in its use in a Carbon0.08 max. wide range of applications. Examples of these are components for liquid fueled rockets, rings, casings and
