Materials

Inconel

Inconel 625 is a nickel-based superalloy with excellent corrosion and heat resistance. Multiple heat cycles have little effect on Inconel 625’s strength, and it can tolerate temperatures of up to 1000°C. Inconel 625 has traditionally been an incredibly expensive material to employ, but the Metal X technology now allows producers to take use of this material for a fraction of the usual cost.

Stronger than Steel

Compared to grade 304 stainless steel, Inconel 625 has a greater tensile strength and performs better at keeping that strength at higher working temperatures.

Furthermore, although having a lower melting point than 304 stainless steel, this variety of Inconel has a greater working temperature limit. This is due to Inconel’s higher thermal strength and resistance to oxidation and scaling.

However, certain substances, such as sulfuric acid, may be more resistant to stainless steel than Inconel. As a result, which of these two metal alloys to choose will be determined by the exact application.

Inconel alloys are preferred for heat treatment and other high-temperature procedures. Stainless steel alloys, on the other hand, are frequently used in sterile production or medical applications.

Applications

Inconel 625 performs exceptionally well in settings characterized by high temperatures, corrosive conditions, and rapid temperature fluctuations. Automotive, aircraft, saltwater or offshore oil and gas, chemical/power processing, and these sectors are all relevant.

Waste-to-Energy

The burning of garbage to create steam for use in heat or power generation is an important component of ecologically efficient waste disposal programs. However, the high halide levels commonly found in municipal garbage (as much as 0.5% in certain situations) create a very corrosive environment at high temperatures.

INCONEL 625 pipe, with a minimum nickel content of 58%, is ideally suited to high halide conditions, since nickel-based alloys have been shown to be highly resistant to halogen attack. For this precise reason, alloy 625 has traditionally been the most popular alloy for use in trash boilers. The INCONEL 625 alloy is generally believed to outperform steel tubing in these types of settings by at least a factor of 10, with its corrosion rate being less than 0.25mm/y (10 mpy).

From Aerospace to Automotive

The aerospace and automobile sectors have also benefited from Inconel’s characteristics. Inconel’s resistance to high temperatures and corrosive conditions makes it ideal for a wide range of applications.

Seawater

Seawater systems are very corrosive conditions that will ruin even the most resistant materials. At a variety of temperatures, Inconel 625 has exceptional resistance to salt chloride. The material is ideal for underwater applications such as wire rope and propeller blades.
