What temperature does Inconel melt?
How strong is Inconel?
When determining strength, tensile strength, corrosion resistance, and even melt resistance can be measured. Inconel 625 has a tensile strength range of 103 - 160 ksi compared to stainless steel's 73.2 ksi and can maintain that strength at higher operating temperatures.
Although exact measurements vary, reported statistics indicate that the melting point of Inconel ranges from 2,350°F to 2,460°F (1,290°C to 1,350°C). Although Inconel 625® has a lower melting point than stainless steel, Inconel 625 is stronger than stainless steel at high temperatures and is also more resistant to oxidation and scaling.
Inconel is considered a superalloy because it is well suited to extreme pressure and high temperature environments and is resistant to corrosion. However, stainless steel alloys are often better suited for sterile manufacturing or medical applications. Superalloys like Inconel tend to be better suited for heat treatment applications and other high-temperature processes.
What is Inconel 625 used for?
In the Inconel series of high-nickel superalloys, Inconel 625 has a nickel content between Inconel 330 and 600. This combination, along with columbium and molybdenum, allows this type of Inconel® to have a very high melting point and perform well at high temperatures. Inconel 625 is particularly resistant to chloride pitting, fatigue stress and has particularly high creep rupture strength and high resistance to oxalic acid. Additionally, Inconel 625 is very easy to solder compared to other Inconel variants.
Due to its high chemical and temperature resistance, superalloy Inconel 625® is used in a variety of applications including jet engine exhausts, flare stacks, seawater equipment and chemical plant equipment.
What is the difference between Monel and Inconel?
Monel is another metal composed of an alloy of nickel and copper. Like Inconel, a nickel-chromium alloy, Monel can be used in extreme conditions at high temperatures.
Monel metal consists of a group of nickel alloys that are highly resistant to chemicals, heat and other media, including seawater. Monel was created at the turn of the 20th century and was used in a wide range of applications, from aerospace applications during the space race to dog tags during the world wars. Nickel alloys are still widely used today, but are more expensive than most other alloys.
Because Inconel is a nickel-chromium alloy, it is resistant to oxidation and is ideal for jobs with different gases and large temperature differences. Inconel is better suited for applications in the oil and gas extraction, aerospace and medical industries. In contrast, Monel's copper additive enhances its corrosion resistance, making it particularly resistant to seawater, hydrochloric acid and sulfuric acid.
Additionally, the advantages of Monel make it ideal for brine applications as well as chemical processing applications. Monel has a very similar melting point range of 2370-2460° F compared to Inconel melting point.
