Ferrite Scope Testing

Ferrite scope testing allows us to accurately measure the ferrite content in stainless steel welds and components, ensuring compliance with welding procedures, material specifications, and service‑condition requirements. At Charlton Metal Testing, our technicians use calibrated ferrite scopes operated by experienced personnel who understand the metallurgical implications of ferrite balance in austenitic and duplex stainless steels.

We support fabrication shops, shutdowns, and in‑service inspection programmes across the UK and internationally, providing fast, non‑destructive measurements that help verify weld quality, prevent cracking issues, and confirm suitability for high‑temperature or corrosive environments. Whether you need spot checks on new welds, verification during production, or assessment of existing plant, we deliver clear, traceable results with straightforward reporting.

Why ferrite scope testing?

• Accurate ferrite number (FN) measurement for austenitic and duplex stainless steels
• Non‑destructive and immediate, ideal for production and in‑service checks
• Helps prevent hot cracking and solidification issues in stainless steel welds
• Supports compliance with WPS/PQR requirements and material specifications
• Portable and efficient, suitable for workshop and on‑site environments
• Useful for high‑temperature and corrosive‑service applications where ferrite balance is critical
• Provides traceable, repeatable results for quality assurance and documentation
