What is incoloy material?

INCOLOY alloy 825 (UNS N08825, W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The nickel content is sufficient for resistance to chloride-ion stress-corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. The molybdenum also aids resistance to pitting and crevice corrosion. The alloy’s chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salt. The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion.

What is difference between Inconel and Incoloy?
The main difference between the two is in their composition. Inconel is mainly of nickel chrome and it generally contains over 50% of nickel, whereas incoloy contain less than 50% of nickel.
What is the difference between Inconel 625 and 825?
The major difference between Inconel 625 and 825 is the nickel content; Inconel 625 contains about 58% of nickel while Inconel 825 contains about 36-48% of nickel. Moreover, they have different melting points as well. The melting point of Inconel 625 is 1350◦C, but it is 1400◦C for Inconel 825.
What is Inconel made out of?
Inconel alloys vary widely in their compositions, but all are predominantly nickel, with chromium as the second element.
Is Inconel 825 magnetic?
The word Inconel is an industry term coined by the International Nickel Company (INCO) to describe alloys high in nickel content, meaning Inconel is not one specific alloy. … Although not naturally magnetic, certain Inconel alloys have magnetic properties, depending on the particular elements involved.
