Ferrite testing in non-destructive testing (NDT) measures the ferrite content in austenitic and duplex stainless steels and welds. This testing is crucial for ensuring material integrity and performance, especially in environments exposed to high temperatures and corrosive conditions. Using devices like ferrite scopes or magnetic induction instruments, the ferrite content is determined to balance mechanical properties and corrosion resistance. Accurate ferrite testing helps prevent issues such as cracking and embrittlement in stainless steel components. It ensures that materials meet industry standards and specifications, promoting reliability and longevity in applications such as chemical processing, oil and gas, and power generation.
