What are Inconel 625 Pipe? It's Grade, Uses and Specifications
Inconel 625 is an exceptionally strong material capable of withstanding extreme pressure, and highly resistant to corrosion - particularly in acidic environments.
This product possesses exceptional resistance to potable and salt water environments, preventing pitting and crevice corrosion as well as chloride stress-corrosion cracking.
Ni-Cr-Mo alloys contain nickel, chromium and molybdenum with added tantalum and niobium to improve toughness and weldability.
What Grade is Inconel 625 pipe?
INCONEL 625 is a nickel-chromium-molybdenum alloy with the addition of niobium. This addition stiffens its matrix, increasing resistance to aqueous corrosion such as pitting and crevice corrosion as well as resisting oxidation and carburization at high temperatures. INCONEL 625 boasts excellent strength and toughness from cryogenic temperatures up to 1800degF as well as possessing outstanding fatigue strength properties.
Material used in marine engineering and aerospace applications, chemical processing, slurry transmission, pollution control equipment and nuclear reactors. It boasts high tensile strength and creep rupture strength as well as being weldable and resisting stress corrosion cracking in chloride salt environments.
Inconel 625 can be applied as a coating on high-strength carbon steel pipes to provide both exceptional strength and corrosion resistance in critical applications. This process often includes an outer mother tube made of carbon steel to add strength while an Inconel 625 inner liner provides corrosion resistance.
What is Inconel 625 Used For?
Inconel 625 pipes have many applications. Due to their superior high temperature and pressure capacities, Inconel 625 pipe are widely utilized in hydraulic and fuel systems designed for aircraft, submarines and spacecraft. Furthermore, their superior tensile strength makes them highly resistant against deformation or fracture.
Alloy 625 is a nickel-chromium-molybdenum alloy containing additional elements like niobium and molybdenum to stiffen its matrix and attain high strength without needing precipitation hardening treatments. Furthermore, this combination gives Alloy 625 excellent corrosion resistance even when subjected to harsh environments.
Owing to these properties, fiberglass makes an excellent material choice for many demanding industrial applications, such as aerospace piping, nuclear reactors and pollution control equipment. Furthermore, its radiation shielding properties and high temperature/stress resistance make it an excellent material choice.
Inconel 625 Pipe Specifications
Inconel 625, commonly referred to by its acronym Incon 625, is an alloy composed of nickel and chromium metals that offers resistance against corrosion and oxidation. As its name implies, Inconel 625 makes an excellent material choice for harsh environments because of its ability to withstand high temperatures without losing mechanical strength.

This nickel-chromium-molybdenum alloy features exceptional corrosion resistance and is capable of withstanding wide temperature variations, whil remaining nonmagnetic with strong fatigue strength and superior ductility as well as resistant stress corrosion cracking properties.
Nickel-based alloys such as this nickel-based alloy are widely utilized in chemical processing applications, particularly where extreme conditions or acid attacks such as nitric acid, sulfuric acid or hydrochloric acid must be endured. They're also an essential part of waste-to-energy systems and refuse-derived fuel production plants, likely playing an essential part in future expansion and development.
What is 625 Pipe Made Of?
Inconel 625 pipe is an industrial-grade nickel-chromium alloy designed to withstand extreme environments and temperatures without losing as much strength as steel, even under pressure and with exposure to aggressive chemicals such as corrosion.
Alloy 625 excels in seawater environments due to its resistance to chloride ion stress corrosion cracking. When combined with its resistance against local attack (pitting and crevice corrosion) and high tensile and fatigue strengths, Alloy 625 makes an ideal material choice for maritime applications like steam liner bellows.
The alloy's strong resistance to sulfuric and phosphoric acids make it an excellent choice for oil and gas applications, including downhole tools and structural components used during drilling operations, natural gas processing operations and risers/tube hangers for oil/gas production. Its ability to withstand stress situations such as risers/tube hangers is another benefit of using this alloy in production environments.
