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. Inconel alloy 718 (Sept 07) Web - Special Metals INCONEL® alloy 718 3 1700°-1850°F Anneal and Age The 1700°-1850°F anneal with its corresponding aging treatment as shown earlier is the optimum heat treatment for alloy 718 where a combination of rupture life, notch rupture life and rupture ductility is of greatest concern. The highest room-temperature tensile and yield strengths are also Inconel® 718 (Alloy 718) Material Data - UNS N07718 UlbrichDescription lnconel® 718 is a nickel-chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 1300 °F (700 °C). The poor age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling.

Jun 05, 2019 · The heat treatment and performance of high-temperature superalloys, and Inconel® 718 in particular, has always been of interest to The Doctor. With greater availability and higher demand for this alloy, understanding its heat treatment will be of great value to the heat treater. Lets learn more. What is a superalloy? The term superalloy was coined just after World War II to describe Welding and Joining - Haynes International, Inc.The introduction of flux elements to the weld also makes it difficult to achieve a proper chemical composition in the weld deposit. While the welding characteristics of Ni-/Co-base alloys are similar in many ways to those of carbon and stainless steel, there are some important differences that necessitate the use of different welding techniques.

It is recommended that the thickness of the root face should not be greater than 1.5mm in a zero gap TIG butt weld. Removable backing strips are very useful to control root bead shape. These can be made from copper, stainless steel or a nickel alloy. Carbon or low alloy steel backing strips should be avoided.ATI 718ATI 718 Alloy is typically supplied in the solution annealed condition.
