Incoloy 840 alloy strip coil for electric tubular heaters help in serving different purposes in different industries.
Tubular heaters are versatile heating elements that are widely used in various industrial, commercial, and residential applications.
Tubular heaters can be formed into virtually any shape, brazed or welded to any metal surface, and cast into metals. The tubular heater’s basic construction consists of a computer-designed helical coil of 80% Nickel 20% Chromium alloy resistance wire fusion welded to the nickel-coated steel terminal cold pins.
In this article, we will be expounding on Incoloy 840 alloy strip coil for electric tubular heaters, its features and applications.
Let’s keep reading.
What Is Incoloy 840 Alloy Strip Coil?
Incoloy 840 alloy strip coil has the characteristics of high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life.
Incoloy 840 alloy strip is a titanium and aluminum austenitic stainless steel containing enough chromium to form and maintain a sufficient scale of chromium oxide, so that it is protected under high-temperature conditions, than the traditional chrome-nickel stainless steel, such as 304 stainless steel strip, high temperature; higher nickel content, compared to the standard 18-8 type stainless steel has better oxidation resistance, its oxidation resistance no less inferior to the use of temperatures up to 1900 degrees (1038 ℃) higher Grade alloy. Therefore, the 840 (S33400) alloy is ideal for the manufacture of electric heat pipes, automotive emission control systems and other high-temperature resistant products.
What Are Incoloy 840 Alloy Electric Tubular Heaters?
Incoloy 840 is a nickel-chromium alloy that is commonly used in high-temperature applications, such as electric tubular heaters. Electric tubular heaters are used to heat liquids, gases, and solids in a variety of industrial applications.
Incoloy 840 electric tubular heaters are designed to operate at temperatures up to 800°C (1472°F) and are known for their excellent resistance to corrosion and oxidation.
These heaters are typically made up of a heating element that is inserted into a tube made of Incoloy 840.
The heating element is usually made of a resistance wire that is coiled and placed inside the tube.
When an electrical current is passed through the wire, it heats up and transfers the heat to the Incoloy 840 tube, which then heats up the surrounding material.
Incoloy 840 electric tubular heaters are commonly used in a variety of industries, including chemical processing, oil and gas, food processing, and water treatment. They are known for their durability, reliability, and long service life, making them a popular choice for high-temperature heating applications.

Benefits Of Using Incoloy 840 Alloy Strip Coil In Electric Tubular Heaters
Incoloy 840 is a high-performance nickel-chromium-iron alloy with excellent resistance to oxidation and high-temperature corrosion. Using Incoloy 840 alloy strip coil in electric tubular heaters offers several benefits, including:
High temperature resistance: Incoloy 840 can withstand high temperatures up to 1000°C (1832°F) without deformation or loss of strength, making it an ideal choice for electric tubular heaters operating at high temperatures.
Corrosion resistance: Incoloy 840 is highly resistant to oxidation, sulfidation, and carburization at elevated temperatures, making it ideal for use in harsh environments where corrosive gases and liquids are present.
Long service life: The high-temperature and corrosion resistance properties of Incoloy 840 ensure that electric tubular heaters made from this alloy have a longer service life than those made from other materials, reducing the need for frequent replacement.
Energy efficiency: Electric tubular heaters made from Incoloy 840 can operate at higher temperatures, resulting in better energy efficiency and faster heating times.
Cost-effectiveness: While Incoloy 840 is more expensive than some other materials, its high performance and long service life make it a cost-effective choice for electric tubular heaters in the long run.
Overall, Incoloy 840 alloy strip coil is an excellent choice for electric tubular heaters operating in harsh environments that require high-temperature and corrosion resistance properties.
How To Choose The Right Incoloy 840 Alloy Strip Coil For Electric Tubular Heaters Supplier From China?
If you want to buy Incoloy 840 alloy strip coil for electric tubular heaters usage, you should know, there are many suppliers and manufacturers produce alloy 840 strips.
But in fact, not all the suppliers have the ability to produce good quality products, some of them just choose cheaper materials but with high price which is not a good choice for users.
Here is a quick guide on how to choose a good Incoloy 840 alloy strip coil for electric tubular heaters supplier.
- First, you should ask the manufacturer whether they can do the inspection themselves before delivery. Most of the large manufacturers have their own inspection team, they will strictly inspect all the goods before delivery.
- Second, you should ask if they use 100% pure raw material to produce your goods, because there are some suppliers use recycled raw material or mixed raw material which may cause problem during using.
- Third, it is better to visit their factory by yourself and check the production line and warehouse by yourself. It will be great if you can check their production process and production equipment. Because it is very important for you to know how they control the quality from process till delivery.
