When you’re sourcing SA 387 Gr.11 Cl.2 Alloy Steel Plates, you’re not just ordering steel — you’re safeguarding an entire power plant, refinery, or pressure vessel project. A single delay or a wrong grade can mean millions lost in shutdown penalties. At Navgraha Steels INC, we understand this risk. That’s why global EPC contractors, boiler manufacturers, and refinery buyers trust us for genuine, certified Chrome Moly plates with on-time dispatch and traceable documentation.
SA 387 Grade 11 Class 2 is a Chrome-Moly pressure vessel steel plate specified under ASTM A387/ASME SA 387 standards.
It is designed for high-temperature service, especially in:
Key reasons buyers choose this grade:
In short: It’s the engineer’s safeguard against high-pressure, high-heat failures.
Procurement teams often face:
At Navgraha Steels INC, we solve these problems with ready stock in Mumbai, transparent pricing, global certifications, and proven export reliability.
Our plates are engineered for industries where safety, compliance, and durability are non-negotiable:
Wherever high heat meets high pressure, SA 387 Gr.11 Cl.2 plates are the buyer’s shield against failure.
SA 387 Gr.11 Cl.2 Chrome-Moly plates are engineered to handle sustained high-pressure and high-temperature environments.
Buyer benefit: This balance of strength, toughness, and ductility ensures long service life in boilers and pressure vessels.
The composition is carefully controlled to deliver creep resistance and heat stability:
| 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 boosts oxidation resistance, while Molybdenum ensures creep resistance at elevated temperatures.
Buyer benefit: Fully compliant for refineries, boilers, and global EPC projects.
We maintain ready stock in standard and custom sizes:
Buyer benefit: Whether you need thin sheets or heavy boiler plates, we deliver cut-to-size material, ready for fabrication.
