Features of INCONEL718 (Shanghai HY Industry Co., Ltd-marketing department)

If you are looking for a material that can maintain high strength over a wide temperature range, consider INCONEL 718 alloy. Let’s take a closer look at the Features of INCONEL718:

INCONEL alloy 718 is a conventional nickel-based superalloy product of Shanghai HY Industry Co., Ltd. Its excellent performance and technical specifications mean that it is used in many high-tech and important industrial applications.

It is often chosen by design engineers due to its high strength at extreme temperature conditions at both ends of the spectrum. It can be used in environments ranging from a low temperature of -252 °C to a high temperature of 704 °C. It exhibits exceptionally high yield, tensile and creep rupture properties across the entire range. It also exhibits excellent tensile and impact strength.

Alloy consists of 50-55% nickel + cobalt (the maximum cobalt content is limited to 1%) and 17-21% chromium. This combination makes the material resistant to corrosion. This includes good oxidation resistance, making it able to withstand the aggressive media present in many applications.

Rest of the composition includes niobium + tantalum (4.75-5.5%), molybdenum (2.8-3.3%) and titanium (0.65-1.15%), among other balancing elements. This is an effective and well-balanced combination of elements that gives the inconel 718 ideal technical performance.

Mechanical behavior

The material is ageable with no apparent detrimental effects. It has a slower response to being treated this way, which means it can be annealed and welded during heating or cooling without any spontaneous hardening.

Its room temperature strength can be significantly improved by precipitation heat treatment, allowing it to withstand this extreme environment. Depending on the end use of the material, different heat treatment solutions are required. Different methods of heat treatment can obtain the best tensile and stress rupture properties for high temperature applications and also maximize performance for use at room temperature or low temperature.

One of the outstanding features of INCONEL 718 alloy is that it is very versatile and easy to use. It exhibits excellent welding properties, especially in terms of resistance to post-weld cracking. Compared with other nickel-based superalloys, especially those hardened with aluminum or titanium, its advantages are greatly improved.

INCONEL 718 material is suitable for high performance applications as it can be easily fabricated into increasingly complex parts.

Application field

INCONEL 718 alloy is commonly used in the aerospace and aviation industries. Needed to be used in the hottest parts of the engine, it is a material that maintains strength and corrosion resistance. The materials used are under challenging conditions, taking into account mechanical and atmospheric stresses. Engineers are always looking for materials that improve engine reliability and efficiency, as well as extend service life. Choose a super alloy, Alloy 718, for a balance between cost and performance.

INCONEL 718 alloy is well suited for use in these situations. For example, it has been used in jet engines and high-speed airframe parts, including wheels, fasteners, instrument parts, bolts, spacers, and buckets. It can also be used to engineer liquid-fueled rockets, assemblies of rings and casings, and various formed sheet metal parts for aircraft and land turbine engines.

At the other end of the temperature range, INCONEL 718 alloy is also used in cryogenic storage tanks.
