Ganpat Industrial Corporation is an Alloy Steel B16 Bolt Manufacturer in India. We forge and machine from our Mumbai works, serving industrial buyers since 1997. The chromium-molybdenum-vanadium chemistry of Alloy Steel B16 Bolts holds strength at elevated temperatures. A higher tempering treatment also maintains this elevated temperature strength. Alloy Steel B16 Stud Bolts and Hex Bolts leave our works regularly. Matching B16 Alloy Steel Nuts serve our power and petrochemical clients. Every batch is machined against ASTM A193 Grade B16 requirements. We pair them with ASTM A194 Grade 7 nuts on request. UNS K14072 heat traceability is carried through to the mill test certificate. We ship from Mumbai to Vadodara, Chennai and Kandla. We export Alloy Steel B16 Bolts to Dubai, Dammam, Rotterdam and Houston.

Alloy Steel B16 Bolt vs ASTM A193 B7 Bolt
Ganpat Industrial’s B16 Alloy Steel Studs use a chemistry close to B7 with one key addition: vanadium.
Alloy Steel B16 Bolt
- Contains 0.25 – 0.35% vanadium
- Rated for continuous use up to 450°C
- Lower relaxation under sustained heat
- Tempered at a higher 650°C minimum
- Pairs with A194 Grade 4 / 7 nuts only
ASTM A193 B7 Bolt
- No vanadium addition
- Practical limit lower than B16
- More prone to relaxation past 400°C
- Tempered at 593°C minimum
- Standard pairing is A194 2H nuts
