Ferrite inspection, also known as ferrite testing, is a non-destructive method that measures the percentage of ferrite in stainless steel:

Ferrite is a metallurgical phase in stainless steel that affects the material’s ductility, toughness, corrosion resistance, and crack prevention.

Ferrite inspection is used to ensure the integrity of materials that are exposed to extreme temperatures and mechanical stresses, such as in the oil and gas, chemical, and power generation industries.

Ferrite inspection uses a magnetic induction test method to measure the magnetic permeability of the material. The results are interpreted in accordance with current specifications and customer requirements.

Ferrite inspection can help prevent potential failures and increased maintenance costs due to corrosion, cracking, or mechanical failures.
