What Is Hastelloy C276 Strip?

Hastelloy C276 strip is a nickel-chromium-molybdenum super nickel alloy strip with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments.

This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

The high chromium content provides the Hastelloy C276 strip good oxidation resistance in continuous service at temperatures up to 1500 Deg F (816 Degree).

Alloy C276 strip has exceptional resistance to a wide variety of chemical environments. Hastelloy C276 strip is used for components that must operate in corrosive conditions, such as chemical processing, waste management, and paper manufacturing systems.

What Are The Characteristics Of Hastelloy C276 Strips?

The tungsten content enhances the Hastelloy’s resistance to oxidizing acids like nitric acid and useful resistance to reducing acids like hydrochloric acid.

Hastelloy C276 strip is one of the few strips materials that can withstand the corrosive effects of wet chlorine gas, hypochlorite, chlorine dioxide and chlorine. It also has good resistance to mixed industrial or oxidizing acids.

The main characteristics of Hastelloy C276 strips are:

  1. Good weldability
  2. Has excellent corrosion resistance
  3. Resistant to stress corrosion cracking
  4. Resistant to oxidation

In What Applications Is Hastelloy C276 Strip Used?

Hastelloy C276 strips are used in a wide range of applications across multiple industries.

The most common uses for this alloy strip are in the chemical processing industry, but it is also frequently used for pollution control, pulp and paper industry, pharmaceuticals, specialty chemicals, pickling operations, nuclear fuel reprocessing, food processing and handling of radioactive waste.

The versatility of Hastelloy C276 strips makes it a popular choice with manufacturers as its durability and resistance to corrosion mean that it will be able to withstand the rigors of industrial processes without corroding or losing its structural integrity.

One of the most common uses of Hastelloy C276 strips is in the oil and gas industry where they are used in power generation plants to protect the turbines from damage due to corrosion.

They are also used in desalination plants where they can be relied upon to resist stress corrosion cracking.

How To Produce One Roll Hastelloy C276 Strip?

The production process of Hastelloy C276 strips is as follows:

Hot rolling: The slab is heated uniformly to the proper temperature by an electric furnace, then it will be rolled into a strip.

Cold rolling: After hot rolling, the steel strip is cooled at room temperature and then rolled into a cold-rolled strip. Cold rolling can improve the strength, hardness and surface finish of the strip.

Annealing: Annealing is a heat treatment process used to make metals more ductile and tough by heating them to above the recrystallization temperature, maintaining a certain time, and then cooling below the recrystallization temperature with water or oil.

Packing: After annealing, the strips are packaged in small rolls or coils, large rolls or coils and straight bars according to different products to prevent rust during transportation.

How To Choose The Right Hastelloy C276 Strip Supplier From China?

If you want to buy Hastelloy C276 strip for industrial usage, you should know, there are many suppliers and manufacturers produce alloy C276 strip and supply to many industries like heat exchanger or chemical industry.

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 Hastelloy C276 strip supplier.

  1. 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.
  2. 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.
  3. 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.
