Inconel is an alloy made of nickel and chromium that is resistant to corrosion, oxidation and heat. It is used in various industries such as aerospace, medical and energy production. The two most popular alloys are Inconel 725 and Inconel 718. While both alloys offer excellent performance in high-temperature applications, there are some significant differences between the two materials. Let’s see how they differ.
Difference Between Inconel 725 and Inconel 718
Their composition is the most significant difference between Inconel 725 and Inconel 718. While both alloys contain nickel and chromium, the amounts of each element and other trace elements vary. For example, Inconel 725 has a higher molybdenum content than similar products (6-8% vs. 2-3%). Increased molybdenum content helps improve corrosion resistance at extreme temperatures (above 800°F).
In addition to differing in composition, the two alloys share other properties in terms of strength and hardness. In general, Inconel 718 has a higher yield strength than similar materials (62 KSI vs. 48 KSI), while Inconel 725 has a higher ultimate tensile strength (117 KSI vs. 112 ksi). Additionally, Inconel 718 is slightly harder than similar materials on the Rockwell hardness scale (34 HRC vs. 32 HRC).
Finally, a significant difference between these two materials is their cost. Due to the increased molybdenum content in Inconel 725 compared to similar materials, this material tends to be more expensive than similar materials due to the increased manufacturing costs to produce this material.
in conclusion:
In summary, there are some key differences between Inconel 725 and Inconel 718 that you should know before choosing the right alloy for your application needs. Generally speaking, if you need an alloy with excellent corrosion resistance at high temperatures, you should choose Inconel 725 because of its higher molybdenum content. However, cost is an important factor. In this case, consider Inconel 718 as it tends to be less expensive than similar products due to the lower manufacturing costs associated with producing it. The final decision will depend on your specific needs, so be sure to carefully weigh all your options before making any final decisions!
