Observations

1. Material-Centric:

   • Element symbols (Fe, Cu, Au) dominate in raw material processing (Groups 24.1, 24.4).

   • Alloy abbreviations (FeMn, FeCr) are specific to steelmaking.

2. Process-Specific:

   • BOF/EAF/SAF differentiate steel production methods.

   • ERW/LSAW specify pipe welding techniques.

3. Cross-Group Usage:

   • CNC/MIG/TIG appear in both structural (25.1) and repair contexts.

   • NDT/UT are critical for quality in pipes (24.2) and tanks (25.2).
