Nickel 718 (UNS N07718), or Inconel 718 bar is a precipitation hardening nickel-chromium alloy that contains molybdenum, iron, columbium, and smaller traces of aluminum and titanium. Designed to exhibit significant yields, high strength, good ductility, and creep rupture properties up to 1300°F (704°C). These characteristics provide alloy 718 good formability, weldability, and cryogenic allowances compared to the metals other nickel based superalloys. Due to its exceptional strength and resistance to extreme temperatures, Inconel 718 round bars is an ideal choice for complex components that must retain their integrity in demanding conditions.

Tensile and Yield Strength
Inconel 718 Round Bars are known for their impressive tensile and yield strengths, making them ideal for demanding applications. The ultimate tensile strength typically reaches around 185,000 psi (1275 MPa), while the yield strength is approximately 150,000 psi (1034 MPa) at a small offset. When aged and treated according to ASTM B983 standards, these strengths are maintained at 1034 MPa and 862 MPa, respectively.

Ductility and Hardness
Inconel 718 Bars exhibit significant ductility, with an elongation of at least 12% over a 2-inch (50 mm) span, and a reduction of area by 15%. After specific aging treatments, the elongation can increase to 20%. The hardness of these pipes, measured after aging, is typically 40 HRC (Rockwell C) maximum. This combination of ductility and hardness ensures the pipes maintain their structural integrity under high-stress conditions.

Temperature Range
Inconel 718 Round Bars retain their excellent mechanical properties across a wide temperature range, performing effectively from cryogenic temperatures (-423°F or -253°C) up to high temperatures (1300°F or 705°C). This broad capability makes them versatile for various demanding applications.

Oxidation and Corrosion Resistance
Inconel 718 Round Bars offer exceptional oxidation resistance up to 1800°F (980°C). They also resist corrosion in the temperature ranges and atmospheres encountered in jet engines and gas turbine operations. This means they can withstand harsh conditions in aerospace and marine environments, making them suitable for use in highly corrosive settings.

Composition and Manufacturing Process
Inconel 718 round bar is composed of a specific blend of nickel (50-55%), chromium (17-21%), and smaller amounts of molybdenum (2.8-3.3%), niobium (4.75-5.5%), and titanium. This combination provides the alloy with its unique properties. The process starts with melting raw materials in a vacuum induction melting (VIM) furnace. To enhance the purity and homogeneity of the alloy, electro-slag remelting (ESR) is often employed. Following these initial steps, the alloy is hot forged or hot rolled into billets or ingots. These are then subjected to solution annealing and age hardening processes to optimize their mechanical properties.

Heat Treatment
Inconel 718 bars are often supplied in a solution-annealed condition to enhance machinability, followed by precipitation hardening (aging) to achieve maximum strength. The standard process involves solution treatment at 1875 ± 25°F (1024 ± 14°C) for 1 to 2 hours, followed by water quenching. An aging treatment at 1425 – 1475°F (774 – 802°C) for 6 to 8 hours, with air cooling, is then performed.

Weldability
Inconel 718 bars demonstrate outstanding weldability, including resistance to post-weld cracking. This makes them suitable for applications that require welding, ensuring that the structural integrity is maintained even after welding processes.
