How Ferrite Tests is Used in Different Industry Sectors

Ferrite Tests 

In order to guarantee adequate toughness, corrosion resistance, and crack prevention, the material testing professionals at Infnita examine the ferrite content in your stainless steel microstructures.

Numerous sectors make use of ferrite testing, such as:

• Energy sources
• Producing Chemical Energy from Pulp and Paper
• Industrial Production Mining
• as well as various others

Explain Ferrite Tests to me

In the microstructure of both austenitic and duplex stainless steels, ferrite can be found as a metallurgical phase or component.

Weld metal made from austenitic stainless steel is affected by ferrite because of:

• Physical characteristics
• Cracking during solidification is not a problem when welding.
• Resistance to corrosion

The role of ferrite in duplex stainless steels is to:

• Physical characteristics
• Effectiveness of Corrosion

Ductility, toughness, corrosion resistance, and crack prevention are all kept in check by an optimal ferrite content.

When should you use Ferrite Tests?

• Determine the amount of ferrite in stainless steel overlays and welds by in-situ and in-lab testing.
• Find out how much ferrite is in your duplex stainless steel pipes, tanks, castings, and other mechanical parts.
• Standards such as API 938C, API 582, NACE MR0175, and NACE MR0103 must be met.

If you need ferrite tests, why not use Infinita Lab?

Infinita Lab’s ferrite testing services can help you avoid costly breakdowns or repairs due to in-service corrosion, cracking, or a lack of desirable mechanical qualities.

Infinita Lab can provide this service to many different sectors because of its team of highly trained and experienced technicians and engineers.

• Energy sources
• Chemicals for the Paper Industry
• The Mining, Manufacturing, and Production of Electricity

Technicians who are experts in tests ferrite

Our personnel are certified by the defined protocols of our quality assurance program, and their skills are continually assessed through audits.

Technicians at Infinita Lab frequently specialize in a particular area of metallurgy, so they are well-equipped to interpret the results and draw conclusions about the material’s qualities. Not all testing companies have such a rigorous quality program, nor do they all have access to such an experienced group of technicians.

Furthermore, Infinita Lab has a staff of around 100 engineers that are knowledgeable and equipped to offer advice to customers who require it while trying to make sense of test results or choose the most appropriate next steps in light of those results.

What is an ideal proportion of ferrite to use?

The sort of stainless steel you’re working with will determine the ideal ferrite content.

Quantity of Ferrite in Austenitic Stainless

Austenitic stainless steel welds perform best with a ferrite content of 4-8%. Micro-cracking of the weld metal during cooling can be effectively controlled at this percentage.

Duplex stainless steel’s ferrite content

The ideal percentage of ferrite in duplex stainless steel is 50 percent. This assures durability, hardness, and strength in the face of corrosion.

To what extent can ferrite be measured?

• The results of a ferrite content test can be seen right away.
•  After placing a probe on the material under study, a magnetic circuit is closed. The magnetic permeability can then be determined.
• This permeability is quantified by comparing the sample to a standard sample whose ferrite content is well-established.
• The percentage of ferrite in the material can be determined by measuring its permeability.
•  A digital readout is used to determine the ferrite content.

Does the procedure cause any harm to the sample?

Our method does not do any damage.  The testing surface should be spotless and completely smooth.

How reliable is testing ferrite?

Calibration pieces are used to assure precision, although the findings can be affected by the component’s unique shape, size, and surface condition. The standard margin of error for this field is 5%.
