Inconel 625

Inconel 625 is a nonmagnetic, corrosion and oxidation resistant, nickel-base alloy. It has high strength and toughness in the temperature range cryogenic to 2000°F (1093°C) which is derived largely from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix. Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions.

Typical applications for Inconel 625 have included heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware and special seawater applications

Strength of Inconel alloy 625 is derived from the stiffening effect with molybdenum and columbium on its nickel-chromium matrix, thus hardening treatments are not required. This combination of chemical elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.

The Inconel 625 versatile and outstanding corrosion resistance under a wide range of temperatures and pressures is a primary reason for its wide acceptance in the chemical processing field. Because of its ease of fabrication, it is made into a variety of element and component for plant equipment. Its high strength enables it be used, for example, in thinner-walled vessels or tubing than possible with other materials, thus improving heat transfer and saving weight. Some applications requiring the combination of corrosion resistance and strength offered by Inconel alloy 625 are tubing, reaction vessels, distillation columns, heat exchangers, transfer piping and valves.

Inconel 625 seamless pipe is available up to 8" NB. Larger sizes are available in welded construction (100% X-ray) and can also be fabricated to order. Inconel® 625 tubing (welded & seamless) is available up 3" OD to both aerospace (AMS 5581) and commercial (ASTM B444) specifications. Redrawn tubes and tubing with tight tolerances can be supplied in almost any size no matter how small the size or quantity.

Inconel 625 Tube is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 1800°F.

Inconel 625 Plate is available in thicknesses ranging from .010 to .156". Inconel® 625 strip in coil from is available in lighter gauges up 24" wide. Inconel® 625 plate is available up 4" thick.

Inconel 625 Round Bar is available in wrought bar up to 8" diameter and larger sizes and shapes may be forged to order.

Inconel 625 Fasteners is used for electrical, chemical and marine hardware, aircraft hot zones and where high strength to weight ratios are required in hi-temperature or corrosive environments.
