Ferrite Testing & Alloy Verification

On-site ferrite measurements and documentation for stainless and duplex welds—verifying FN targets for corrosion resistance and code compliance.

FERROUS CONTENT VERIFICATION FOR STAINLESS SYSTEMS

Ferrite percentage directly impacts the corrosion resistance, mechanical properties, and weldability of stainless steel components. We provide rapid, non-destructive field measurements that validate material composition without destructive testing.

Our certified technicians use calibrated ferrometers to measure ferrite number (FN) across weld overlays, heat-affected zones, and base materials. These measurements ensure that stainless steel components meet design specifications and code requirements.

We understand that ferrite content is critical for preventing stress corrosion cracking in chloride environments and ensuring adequate toughness in cryogenic applications. Our testing programs help clients avoid costly failures and ensure long-term asset reliability.

SERVICES & CAPABILITIES

Field Measurements

Portable ferrometers deliver precise FN values on weld overlays, duplex stainless, and clad components without cutting samples.

  • Calibrated to AWS A4.2 and EN ISO 8249
  • Profiles ferrite at root, cap, and heat affected zones
  • Immediate acceptance / rejection decisions

Reporting & Compliance

We package FN readings with weld maps and photographs so QA/QC teams have traceability for pressure equipment registration or client turnover packages.

  • Structured reports aligned to API 582
  • Integration with welding procedure qualification records (PQRs)
  • Support for corrosion engineers and metallurgists
HOW WE PARTNER

Whether qualifying new welding procedures or verifying in-service repairs, our ferrite testing team keeps your stainless assets within specification.

We work alongside your welding engineers and metallurgists to interpret results and make informed decisions about procedure adjustments or material substitutions. Our reports provide the technical detail needed for code compliance while remaining accessible to project teams.

Our ferrite testing services support both new construction and maintenance activities. We can quickly mobilize to fabrication shops, field sites, or operating facilities, providing immediate feedback that keeps projects moving forward without delays.
