SA 387 Gr.91 Cl.2 Coils Supplier & Exporter in India – Navgraha Steels INC (Mumbai, Maharashtra)

When sourcing material for boilers, pressure vessels, or EPC shutdowns, the stakes are high. A single wrong shipment—wrong grade, delayed delivery, or uncertified supply—can bring an entire project to a halt.

At Navgraha Steels INC, we understand these risks. That’s why we supply IBR, PED, and EN 10204 certified SA 387 Gr.91 Cl.2 coils, ready for global export with mill test certificates, seaworthy packing, and on-time dispatches. Our coils are trusted by refineries in the GCC, power plants in Africa, and EPC contractors worldwide.

What Are SA 387 Gr.91 Cl.2 Alloy Steel Coils and Why Do EPC & Boiler Projects Depend on Them?

SA 387 Grade 91 Class 2 is a Chrome-Moly-Vanadium alloy steel engineered for long-term elevated temperature service. In coil form, it provides engineers and EPC buyers with:

  • Flexibility in fabrication (slitting, cutting, forming into plates or components)
  • High creep resistance at 600°C+ continuous operation
  • Oxidation & corrosion resistance in refinery and power environments
  • Reliable compliance with ASME, ASTM, IBR, and PED standards

In Class 2 condition (normalized + tempered), these coils deliver higher strength and creep resistance compared to Class 1, making them the first choice for boilers, reactors, and pressure vessels.

The Real Pain Points Buyers Face While Procuring SA 387 Gr.91 Cl.2 Coils

Procurement managers and engineers face challenges that go beyond just finding a supplier:

  • Wrong grade/class supplied → project rejection & costly rework
  • No IBR/PED/EN 10204 certification → non-compliance penalties
  • Long lead times → shutdown delays, contractual fines
  • Poor packaging → rust, edge damage during shipping
  • Hidden charges → budget overruns after PO placement

At Navgraha Steels INC, we eliminate these risks with:

  • Ready stock in Mumbai + mill allocation support
  • IBR, PED, CE, EN 10204 3.1/3.2 certifications
  • Seaworthy export packaging & rust protection
  • Transparent CIF/FOB pricing with no surprises

Proven EPC approvals & references

Applications of SA 387 Gr.91 Cl.2 Coils Across Global Industries
