Advantages of ASTM A193 B7M Stud Bolts
ASTM A193 Grade B7M is widely specified for bolting used in sour service and corrosive environments. Compared with standard B7 material, B7M offers:
- Controlled hardness suitable for NACE applications
- Improved resistance to sulfide stress cracking
- Reliable performance under high pressure and temperature
Combined with ASTM A194 2HM heavy hex nuts, these stud bolts are ideal for flange joints in oil & gas, petrochemical, and refinery piping systems.
Hot-Dip Galvanizing for Enhanced Corrosion Protection
All stud bolts in this shipment were hot-dip galvanized according to ASTM F2329, providing:
- Uniform zinc coating thickness
- Excellent corrosion resistance during storage and service
- Extended service life in harsh outdoor and industrial environments
This makes hot-dip galvanized B7M stud bolts for Iraq projects particularly suitable for long-term operation.
