Inconel 625 VS Inconel 800
What is the difference between Inconel 625 and Inconel 800?
These material grades have lower nickel content compared to Inconel 625. These Inconel wires are resistant to oxidation, carburization, and high temperature corrosion. Inconel 800 is known for its high carbon content, high creep and rupture properties compared to Inconel 625 alloy.
What is the yield strength of Inconel 625 pipe?
Mechanical Strength of Nickel Alloy 625
For Grade 1 N06625 alloy, the tensile strength is at least 827 MPa (120 kpsi) after annealing heat treatment (annealing temperature ≥ 871°C/1600°F). The yield strength is at least 414 MPa (60 kpsi) and the elongation is at least 30%.
What is the difference between Inconel 625 and Inconel 725?
INCONEL 625 alloy contains small amounts of cobalt and silver, which are absent in INCONEL 725 alloy. INCONEL 725 alloy has a higher titanium content (1-1.7%, while INCONEL 625 alloy has a maximum of 0.4%), and the rest is made up of iron, while INCONEL 625 alloy has a maximum of 5%.
What is the difference between Inconel 625 Grade 1 and Grade 2?
The main differences between the two grades are as follows: Heat Treatment: Grade 1 is typically annealed at around 1600°F to 1800°F (approximately 871°C to 982°C) to provide good ductility and corrosion resistance while maintaining higher strength than Grade 2.
Incoloy 800 vs Inconel 625 – What's the Difference
What is Incoloy 800?
Incoloy 800 is a versatile alloy designed for applications requiring excellent corrosion resistance, high strength and heat resistance. It has exceptional properties such as excellent creep rupture strength and oxidation resistance up to 1050°C (1922°F). This makes it ideal for use in harsh environments such as petroleum refining.
What is Inconel 625?
Inconel 625 is a nickel-based high-temperature alloy known for its superior strength and high-temperature corrosion resistance. It is well suited for applications such as seawater, chemical processing, heat exchangers, etc. Its many excellent properties make it an indispensable material in many industries around the world.
Difference Between Incoloy 800 and Inconel 625
Composition
Incoloy 800 is a nickel-iron-chromium alloy that is highly resistant to oxidation, carburization, and sulfidation. Its nominal composition is 32% nickel, 46% iron, 21% chromium, and 0.5% manganese. It also contains trace amounts of aluminum, titanium, and copper. In contrast, Inconel 625 is a nickel-chromium-molybdenum alloy that offers excellent corrosion resistance in a wide range of environments. Its nominal composition is 58% nickel, 22% chromium, 9% molybdenum, 3.5% niobium, and 1% iron. It also contains trace amounts of titanium, aluminum, and cobalt. Therefore, Incoloy 800 has more iron and less nickel than Inconel 625.
Conclusion
In summary, choosing between Incoloy 800 and Inconel 625 depends on your specific needs, budget, and conditions. If you need a material that can withstand high temperatures, oxidation, and carburization, Incoloy 800 may be the right choice for you. If you need a material that can resist corrosion in aggressive environments such as seawater, acids, and chloride solutions, Inconel 625 may be a better choice. Ultimately, it is critical to consult with a material expert or supplier who can recommend the most appropriate material for your industrial application based on your needs and specifications.
