Key Composition Differences

The biggest difference between inconel and incoloy alloys is what they are made of. Inconel alloys have a lot of nickel, usually more than 60%. Incoloy alloys have more iron, so they act differently. Both are nickel-based alloys, but their mix of metals makes them special.

Here is a simple table to help you compare:

Alloy Type Main Elements Nickel Content Iron Content Typical Use
Inconel Nickel, Chromium, Molybdenum 58–72% Low Aerospace, Oil & Gas
Incoloy Nickel, Iron, Chromium 30–46% High Chemical Processing, Power

Inconel alloys use lots of nickel for strength and to stop rust. Incoloy alloys use more iron, which helps them last longer. Both types are nickel-based alloys, but incoloy is often called a nickel-iron-chromium alloy because it has more iron.

Main Property Distinctions

Inconel alloys and incoloy alloys act differently when they get hot or are under pressure. Inconel alloys stay strong even at high temperatures. Incoloy alloys work well for a long time when exposed to heat and chemicals.

Here is a table that compares their mechanical properties:

Property Inconel Alloys Incoloy Alloys
Yield Strength (MPa) 280 – 1,200 240 – 600
Ultimate Tensile Strength (MPa) 700 – 1,200 485 – 690

Inconel alloys have higher yield and tensile strength. This makes them good for tough places like jet engines or oil rigs. Incoloy alloys are better when you need steady performance for many years, like in heat exchangers or chemical plants.

The uses for each alloy are different:

Alloy Type Common Applications Industry Sector
Inconel Aerospace components, oil and gas systems Aerospace, Oil and Gas
Incoloy Chemical processing, high-temperature use Chemical Processing

Think about where you will use the alloy before you choose. If you need something strong at very high temperatures, pick inconel alloys. If you want something that lasts a long time in hot or harsh places, incoloy alloys are a good choice.

Inconel Composition and Strength

Inconel is special because of what it is made of. Most inconel grades have a lot of nickel, between 58% and 72%. Chromium is also in inconel, from 14% to 23%. Iron makes up about 5% to 10%. There are small amounts of molybdenum, niobium, aluminum, and titanium. Nickel helps inconel fight rust and stay strong when hot. Chromium protects the outside from getting damaged by air. Molybdenum and niobium help stop cracks and pits.

Here is a table that shows what is in some inconel grades:

Inconel Grade Nickel (%) Chromium (%) Iron (%) Molybdenum (%) Niobium (%)
600 ≥72.0 14–17 6–10 0 0
625 ≥58.0 20–23 5 8–10 3.15–4.15
718 50–55 17–21 18 2.8–3.3 4.75–5.5

Bozhong sells inconel in plates, sheets, bars, pipes, and wires. You can pick the type and grade that works for your job.

High-Temperature and Corrosion Resistance

Inconel stays strong even when it gets very hot. You can use it where other metals break down. Inconel keeps its strength above 1000°C. For example, inconel 625 works up to 982°C. Inconel 718 works up to 980°C. This makes inconel great for places with lots of heat.

Inconel also does well against rust and damage from chemicals. It gets a score of 9 out of 10 for fighting corrosion. This is better than stainless steel and many other alloys. You can see how inconel compares in this chart:

It is used in nuclear parts and chemical plants.

Here is a table that shows how these alloys do in different places:

Alloy Temperature (°C) Environment Performance Summary
Inconel 617 750 Helium atmosphere Gets weaker from carburization.
Incoloy 800H 750 Helium atmosphere Stays strong because of a silicon oxide layer.
Inconel 617 950 Graphite dust-coated Loses strength and stretch from carbon moving inside.
Incoloy 800H 950 Graphite dust-coated Keeps its properties because the surface blocks carbon.

Studies found that Incoloy 800H makes a double oxide layer. This helps it fight oxidation better than Inconel 617.

Cost and Fabrication Considerations

You should also think about cost and how easy it is to shape or weld. Inconel is harder and needs special tools to work with. Incoloy is easier to shape and weld. You can make complex parts with it. This saves time and money for big jobs.
