Inconel® Alloy 718 (UNS N07718.W.Nr. 2.4668), is a precipitation-hardenable nickel-chromium alloy, useful for its exceptionally high yield, tensile and creep-rupture properties. Alloy Metals and Tubes, International is a distributor of Inconel® Alloy 718 tubing, it is one of our most popular alloys. While we specialize in large OD custom tubes with heavy walls for use in the oil and gas industry; we inventory a range of sizes, from as small as .040″ OD to as large as 6.0″ OD. We manage manufacturing, heat treating to the specifications, machining and inventorying.
Inconel® Alloy 718 tubing, because of its composition, has excellent corrosion resistance. Nickel is a factor in its corrosion resistance in presence of acidity and alkalinity; and contributes to combating chloride-ion stress corrosion cracking. Inconel® Alloy 718 tubing is able to withstand attack by oxidizing media and sulfur compounds due to the Chromium content. Molybdenum allows the alloy to resist pitting. Inconel® Alloy 718 tubing can be easily fabricated and its weldability makes it an attractive choice in a variety of applications, mainly in aerospace and oil and gas industries.
If Inconel® Alloy 718 tubing is going to be machined, formed, or welded, it is purchased in the annealed or stress relieved condition. Once fabricated, it can be heat treated as required by the applicable specification. To produce optimum properties and take advantage of its precipitation-hardening character, several heat treatment procedures have been developed. Literature detailing the different phases developed during heat treating should be studied and compared to the properties desired before any actual heat treating takes place.
High-performance nickel alloys for sour oil and gas fields. Inconel 718 Pipe hardened nickel-based alloys and cold-worked solid nickel-based alloys offer many advantages such as high strength, toughness, low magnetic permeability and excellent corrosion resistance. Inconel 718 Pipe has proven to be a valuable and versatile material that is able to solve a wide variety of design and application problems. Inconel 718 Pipe has the ability to resist low temperature aggressive corrosion environments, as well as hostile high temperature environments. The excellent weldability of the alloy, and its ability to be joined very successfully to other alloys with different compositions.

T ypical 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
