How Ferrite Testing Benefits Your Business in Malaysia

Ferrite testing is a non-destructive inspection method that delivers instantaneous results. Ferrite testing benefits most companies, especially those in the oil and gas, power generating and manufacturing industries, as their structures are more susceptible to hot cracking due to excessive amounts of ferrite.

Here, we compile three essential ferrite testing benefits. But first, let us start with the fundamental aspects of ferrite testing.

An Introduction to Ferrite Testing

The ferrite test is a quick, low-cost, and accurate approach to determining the amount of delta ferrite in austenitic and duplex stainless steel. Ferrite testing can help you find the right ferrite content balance to ensure durability, corrosion resistance, and crack prevention.

What is Ferrite?

As mentioned above, there are two types of stainless steel: austenitic and duplex. Within these two forms, there are intricate microstructures, including ferrite. Ferrite influences both types of steel differently as they have different compositions.

For austenitic stainless steel, ferrite affects:

  • The structure’s resistance to corrosion
  • The structure’s mechanical properties
  • The structure’s weldability

Meanwhile, the ferrite content in duplex stainless steels only affects:

  • The structure’s resistance to corrosion
  • The structure’s mechanical properties

What is Ferrite Testing Used for?

Mainly, ferrite testing can be used to inspect:

  • Austenitic stainless steels
  • Duplex stainless steel, including castings, tanks, pipes and mechanical components
  • Weldments, castings, forgings, weld overlays and wrought materials
  • Normal construction steel with austenitic welded cladding
  • Weldments, castings, forgings, weld overlays and wrought materials
  • Weld materials
    • Category A-D welds
    • Butt/fillet welds
    • Stainless weld overlays on non-ferrous interfaces
  • In-service and in-construction components

How to Conduct a Ferrite Content Analysis

First, a minimum and a maximum material thickness of the specimen are necessary for successful ferrite testing. Next, skilled technicians would place a single probe on the sample’s surface to capture and record accurate readings by measuring any magnetic permeability.

The test results are then interpreted based on present needs and customer specifications. Lastly, detailed reports are generated, provided either in the form of profile readings (percentages) or as ferrite numbers.

Ferrite Testing Benefits

You’ll enjoy various ferrite testing benefits if you opt for this non-destructive method. Here are some of the main ferrite testing benefits that you should know:

Rapid and Reliable
Ferrite testing is a cost- and time-effective testing method that can provide immediate and accurate results. Simply put, you can get the ferrite content measurement of a structure in little to no time. Not only that, but this method also leaves no marking behind.

Ease of Use
The testing is typically conducted on-site with Fischer’s portable test machine. Our experienced workers can utilise the convenience of portable equipment, so you can get reliable results efficiently, rapidly, and accurately.

Prevent Potential Failures
Ferrite testing determines if the heat treatment applied to the structure has achieved the required performance balance. Furthermore, it checks your material and identifies the threat of any potentially harmful third phases that could later impair the effectiveness of stainless steels, as well as reveal any flaws in the weld strength.
