The relevant ASTM standard for ferrovanadium in the United States is:
ASTM A481 – Standard Specification for Ferrovanadium
Parameter
Requirement (Typical for FeV50 Grade)
Vanadium content
50 ± 1.5 % (actual range specified by grade: FeV40, FeV50, FeV60, FeV80)
Aluminum (max)
1.5 % for FeV50; lower for higher V grades
Silicon (max)
2.0 % for FeV50
Carbon (max)
0.10 % for low‑carbon grades; up to 0.20 % for regular grades
Phosphorus (max)
0.05 %
Sulfur (max)
0.05 %
Shape
Lump, crushed, or granular as agreed
Size
Specified by buyer (e.g., 10–80 mm for lump)
Testing & Certification
  • Chemical analysis by wet or spectroscopic methods.
  • Sieve analysis for size grading.
  • Certificate of compliance to ASTM A481 required for most steel mill purchases.
International equivalents
  • ISO 5448​ (Ferrovanadium — chemical composition)
  • JIS G2309​ (Japan — ferrovanadium grades)
