What is INCOLOY 825 equivalent material?

Alloy 800 Incoloy 800 UNS N08800

Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It is an alloy that provides high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments. Alloy 825 is similar to alloy 800 but has improved resistance to aqueous corrosion.

What is the difference between INCOLOY 825 and 800?

Incoloy 825 | Alloy 825 | UNS N08825

It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids.

What is the difference between incoloy 825 and 925?

Alloy 825 (Incoloy 825, UNS N08825, 2.4858) and Alloy 925 (Incoloy 925, UNS N09925) are nearly identical in composition, and therefore provide very similar corrosion resistance and physical properties. However, Alloy 925 provides significantly higher levels of strength as it benefits from precipitation strengthening.

What is the forging grade of Inconel 825?

Forging. The forging temperature range for this alloy is 2150/1600ºF (1180/870ºC). Optimum corrosion resistance is obtained when finish forging is carried out between 1800/1600°F (980/870ºC).

What is the difference between Inconel and Incoloy?

When comparing the differences the most basic difference between them is their composition. Inconel is an alloy of nickel-chrome and usually contains over 50 percent nickel, whereas Incoloy, is an alloy of nickel-iron-chromium, and contains less than 50 percent nickel content.

What is the difference between Inconel 625 and INCOLOY 825?

The two alloys are quite different in terms of composition. Incoloy 825 is an austenitic nickel-iron-chromium alloy that contains small amounts of molybdenum, copper, and titanium. Inconel 625, on the other hand, is a nickel-chromium-molybdenum alloy that contains small amounts of iron, manganese, and silicon.

What is upset disk forging?

Upset forging involves locally heating a metal bar and then, while holding it firmly with special tooling, applying pressure to the end of the bar in the direction of its axis to deform it.

What is a forging die?

Forging dies are usually made of high-alloy or tool steel. Dies must be impact- and wear-resistant, maintain strength at high temperatures, and have the ability to withstand cycles of rapid heating and cooling.

What is the process of forging?

Forging is a manufacturing process involving the shaping of a metal through hammering, pressing, or rolling. These compressive forces are delivered with a hammer or die. Forging is often categorized according to the temperature at which it is performed—cold, warm, or hot forging. A wide range of metals can be forged.

Why forging is better than casting?

Strength: Forged metals have more relative strength than cast and plate metals, even when the parts are formed using the same alloy. Reduced Likelihood of Defects: Other processes may result in metal pieces with shrinkage and cold pour issues, cavities within the cast, or porosity.

Other Forgings are Available
