When your project runs on boilers, refineries, or high-pressure vessels, a single wrong shipment can cost you millions in shutdown losses. That’s why sourcing SA 387 Gr.11 Cl.2 Chrome Moly Alloy Steel Coils requires more than a vendor — it needs a partner who understands urgency, compliance, and precision. At Navgraha Steels INC, we deliver certified alloy steel coils with guaranteed traceability, timely dispatch, and export-ready packaging.
SA 387 Grade 11 Class 2 is a Chrome-Moly alloy steel, engineered under ASTM A387/ASME SA 387 standards, specifically for elevated temperature service. In coil form, it gives buyers:
👉 In short: SA 387 Gr.11 Cl.2 coils are the backbone of pressure vessel safety.
Procurement isn’t just about buying steel — it’s about avoiding risks:
At Navgraha Steels INC, we remove these risks by supplying ready stock coils in Mumbai, certified to global standards, with clear pricing and proven export track record.
Our coils are used where strength, compliance, and reliability are non-negotiable:
👉 Wherever high heat meets high pressure, SA 387 Gr.11 Cl.2 coils are the engineer’s trusted choice.
SA 387 Gr.11 Cl.2 coils are engineered for strength, heat resistance, and weldability:
👉 Buyer benefit: Guarantees longer service life and lower maintenance downtime in boilers, refineries, and power plants.
The coil chemistry provides oxidation resistance and creep strength:
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.05 – 0.20 |
| Manganese (Mn) | 0.30 – 0.60 |
| Silicon (Si) | 0.50 – 1.00 |
| Chromium (Cr) | 1.00 – 1.50 |
| Molybdenum (Mo) | 0.45 – 0.65 |
| Phosphorus (P) | ≤ 0.035 |
| Sulphur (S) | ≤ 0.035 |
👉 Buyer benefit: Chromium improves resistance to scaling/oxidation, while Molybdenum ensures creep resistance at high temperature.
👉 Buyer benefit: Fully compliant coils, accepted in EPC, refinery, and global power projects.
We supply coils in standard & custom specifications:
