You may ask why choose this Hastelloy to form the filter instead of other metals or alloys. That’s because Hastelloy is much more stronger than any others. Same as Monel filter, Filson Hastelloy filter also uses a nickel-based raw material. There are some differences between them. View the following comparison and find the most suitable material:

Filson Hastelloy filter for your applications


  • The mechanical properties of Monel are comparable to those of alloy steel, and the tensile strength is relatively high and can be about 30% higher than that of Hastelloy.
  • In addition, the material is non-magnetic, high in strength, good in ductility and weldability.
  • Monel has good corrosion resistance and conventional processes (hot rolling, forging, annealing, etc.) have little effect on it.
  • Monel filter can be used in certain applications where require non-magnetic and resistant media to strong reducing corrosion.

Hastelloy C-276 supplier and manufacturer


  • Hastelloy has been widely used in some very harsh industrial environments due to its good corrosion and high temperature resistance.
  • After years of upgrading, there are many product grades ( C-276, C-2, C-2000, B-2, B-3, G-30 ).
  • Strong reducing corrosive environments and serious oxidizing environments will not have a great impact on Hastelloy.
  • Due to the better performance, the price of Hastelloy has been much more expensive than Monel alloy.

Hastelloy cartridge filter housing

Hastelloy has a very stable austenitic matrix organization and contains a large amount of alloy element Ni, which is easy to be welded and secondary cold processed. Filson can offer you the quality Hastelloy wire mesh or multi-layer sintered Hastelloy disc for you to process, or just deliver the finished filter to you.

Filson also manufactures Hastelloy perforated sheet. As one of our best selling products, it is customized in different hole sizes, pitches, sheet sizes and thickness according to customers’ requirements.

Hastelloy filter element supplier

Among all grades of Hastelloy, C-276 is the most commonly used grade to fabricate Filson Hastelloy filter. It is one of several materials that are resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions. Also, it has significant resistance to highly concentrated chloride salt solutions, such as ferric chloride and copper chloride.

Is Hastelloy Better than Stainless Steel?

To some extent, it is.

Hastelloy and stainless steel are two kinds of alloys which contain metals as the major component and nonmetals as a minor component. The two alloys are both resistant to corrosion, however, due to the special composition with more nickel in it, Hastelloy is better than stainless steel.

Hastelloy features:

  1. Nickel-based alloy which is called a superalloy
  2. Composed of nickel, chromium and molybdenum
  3. High temperature resistance up to 1090℃
  4. Excellent corrosion resistance in both oxidizing and reducing atmosphere
  5. High stress resistance
  6. Easy to be welded and fabricated
  7. Resistant to stress cracking corrosion
  8. Suitable for chemical processing, aerospace and pharmaceutical industry

Stainless steel features:

  1. An alloy of steel with a high chromium content
  2. High corrosion resistance
  3. Excellent performance in acid environments
  4. Available in forms of sheet, plate, tube and wire
  5. Outstanding tensile strength
  6. Composed of iron, chromium and carbon
  7. Suitable for architecture, pulp and paper, chemical processing, food and beverage

In brief, Hastelloy is a more expensive alloy comparing to stainless steel. And when you are dealing with an extremely corrosive problem and stainless steel is not regarded as the suitable material for the process, then Hastelloy can be the best alternative.

What are the Differences Among Various Grades of Hastelloy?

At present, Hastelloy is mainly divided into three series: B, C and G. It is mainly used for strong corrosive occasions where iron-based Cr-Ni or Cr-Ni-Mo stainless steel and non-metallic materials cannot be used.

There are some common grades of Hastelloy, see the properties below:

  1. Hastelloy B-2 is a nickel-molybdenum alloy with excellent corrosion resistance in reducing environments.
  2. Hastelloy B-3 is an upgraded version of B-2 with excellent resistance to hydrochloric acid at any temperature and concentration.
  3. Hastelloy C-4 has good thermal stability and great toughness and corrosion resistance under high temperature of 650 – 1040℃.
  4. Hastelloy C-22 has better uniform corrosion resistance than C-4 and C-276 in oxidizing media and provides excellent localized corrosion resistance.
  5. Hastelloy C-276 has good resistance to oxidizing and moderate reducing corrosion and outstanding stress corrosion resistance.
  6. Hastelloy C-2000 is the most versatile corrosion resistant alloy in both oxidizing and reducing environments.
  7. Hastelloy G-30 is a nickel-based alloy with high chromium content that performs well in phosphoric acid and other strong oxidizing acid mixtures.
  8. Hastelloy G-35 is an upgraded version of G-30 with better corrosion resistance and thermal stability.

In today’s market, the most frequently used grades of Hastelloy are B-2, C-22, C-276 and C-4. With different composition, the material features vary from one to another. In order to enhance the efficiency of the final product, you are recommended to choose the right raw material. Contact Filson today and know more about the differences.

How to Clean Hastelloy Filter?

To keep the efficiency of your Hastelloy filter, you’d better to clean and wash the filter after a period of using. The correct cleaning method can help you recover the effectiveness, however, if applying the wrong way, the filter would be damaged.

1. Blowback and backwash flushing

This is the common and simplest cleaning method for almost all filters. In order to achieve the purpose, the method relies on a reverse flow of liquid or gas to force particles out of the media structure.

For those deeply embedded contaminants, multiple times of the repeated operation is required.

2. Soak and flush

Chemical soaking is the usual cleaning method for Hastelloy filter by dipping the filter in a detergent solution, generally acid solutions. Through the process, the contaminants will be loosened, removed or dissolved. It’s suitable for dealing with metal oxides like ferro rust.

3. Ultrasonic washing

Ultrasonic cleaning is the most effective procedure for deeply embedded particles. And a better results can be gained using with chemical solvents.

4. Hydro blasting

Hydro blasting is a technique which is usually used to replace other cleaning methods if the particles have grossly adhered to the media surface. It won’t reach deeply to the internal media structure, but it’s enough for the cleaning of common filters.

You can use one of these methods to clean you Hastelloy filter, or you can combine them together to realize a higher efficiency to handle a seriously clogged product. If you have any doubt, just consult our professional specialists at any time.
