Quantify Steel Cleanliness Accredited, Defensible, and Delivered Fast
AADFW measures nonmetallic inclusions in steels and alloys to verify melt cleanliness, process control, and fitness for mission-critical service. We combine ISO/IEC 17025–accredited inclusion rating testing with calibrated imaging and faster turnaround than slow, global labs, so qualifications and lot release stay on schedule.

Why Inclusion Rating Testing Matters
Nonmetallic inclusions—sulfides, oxides, silicates, aluminates, can initiate fatigue cracks, reduce toughness, distort machining, and compromise weld performance. Quantified inclusion content confirms steelmaking practice (deoxidation, secondary refining), billet/forging quality, and vendor consistency. For aerospace and oil & gas hardware, verified cleanliness supports drawing compliance, MRB dispositions, and long-term reliability.
AADFW’s Approach: Precision, Speed, and Proof
- Accredited & precise: Performed under ISO/IEC 17025 with controlled prep, calibrated optics, and documented measurement procedures.
- Faster results: Alloy-specific prep routes, standardized field counts, and decision-ready photo plates compress lead times without sacrificing rigor.
- Trusted by engineers: Clear acceptance call-outs tied to your print/spec, location maps, and metallurgical context that stands up to OEM and regulatory audits.
Inclusion Rating Testing Capabilities
- Targeted Sectioning & Orientation
Non-thermal sectioning at specified locations; longitudinal and transverse orientations captured when required for rolled/forged product.
- Preparation & Etching
Artifact-free grinding/polishing per ASTM E3 and micro-etching per ASTM E407 to maximize inclusion contrast (no pull-out or smearing).
- ASTM E45 Inclusion Rating (Primary Method)
- Results reported by type and severity, with field counts (N) and worst-field identification; photo documentation included.
- Reporting & Traceability (Audit-Ready)
Location map, etchant/time, magnification, E45 tables by type/series/thin-heavy, acceptance summary (go/no-go), and instrument/calibration references linked to heat/lot and PO.
Industries We Support
- Aerospace: Landing-gear steels, fasteners, shafts, bearings, cleanliness tied to fatigue and fracture allowables.
- Oil & Gas: Pressure-boundary steels, risers, and downhole tools where inclusions drive crack initiation and service scatter.
- Defense & Advanced Manufacturing: Forgings and bar products demanding consistent melt quality and documented compliance.
Trusted by engineers and QC managers across mission-critical industries.
