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. The ease and economy with which INCONEL alloy 718 can be fabricated, combined with good tensile, fatigue, creep, and rupture strength, have resulted in its use in a wide range of applications. Examples of these are components for liquid fueled rockets, rings, casings and various formed sheet metal parts for aircraft and land-based gas turbine engines, and cryogenic tankage. It is also used for fasteners and instrumentation parts.

HEAT TREATING AND MECHANICAL PROPERTIES
1 Determination of operating Temperature. The lower critical temperature (AC1) and upper critical temperature (AC3) were determined by Grange empirical formula [9] as presented here AC1( 0 C) = (133 – 25Mn + 40si + 42Cr – 26Ni) – (32) 5/9----------------1.1 AC3( 0 C) = (1570 – 323C – 25Mm + 80si – 3Cr – 32Ni) – (32)5/9-------1.2 The carbon equivalent and estimate of austenite carbon in equilibrium are calculated from the chemical composition as given by [11] and [1] Ceq = %C + %Mn + (Cr+Mo+v) + %(Ni+Cu)…… … ……1.3 6 5 15 Vol.9, No.8 Effects of Heat Treatment 695 Co = T - 0.17Si - 0.95………………………………….1.4 420 Where T = Austenite Temperature The results are presented in Table 1.
