What are the differences between Inconel 625 and Inconel 718 used for pipe fittings?
The major difference between the two is that the Inconel 625 is -firstly a nickel-based alloy while the Inconel 718 is a nickel and cobalt-based alloy. They both are used for pipe fittings and are also called Inconel pipe fittings.
The Inconel 718 has more hardness and strength and the Inconel 625 pipe fittings are more resistant to corrosion than the other. The alloy 718 has the highest melting point while the other Inconel 625 fittings do not have such a high melting point but it is more likely to have corrosion resistance.
What are the corrosion resistance properties of ASTM B366 UNS N06600 elbow, and how do they compare to other materials used for pipe fittings?

What are the temperature limitations of alloy 600 fittings according to industry standards?
The alloy 600 is used in various industries thanks to its unique properties. The Inconel 600 alloy is also used in nuclear power plants for its quality of resistance to corrosion even in high-purity water.
Although, there are some temperature limitations too. The alloy 600 fittings can work efficiently in the range of 1600 degrees Fahrenheit to 2250 degrees Fahrenheit. But, they are best avoided for applications between 1200 degrees Fahrenheit to 1600 degrees Fahrenheit.
