Navgraha Steels INC supplies SA 387 Gr 22 Cl 2 Plates, Sheets & Coils, sourced from leading global mills like Sail, AMNS, JSPL, Evonith, Nippon Yakin, Outokumpu, Special Metals, VDM, and ATI. A high-performance chromium-molybdenum alloy steel, this grade is engineered for boilers, pressure vessels, and reactors operating at high pressures and elevated temperatures. Every supply is backed by EN 10204 3.1/3.2 mill test certificates, IBR approvals, and international inspection reports.
When you are procuring alloy steel plates for boilers, refineries, or nuclear plants, one wrong shipment can cost crores in shutdown penalties and credibility loss.
When sourcing alloy steel sheets for boilers, refineries, or nuclear power plants, the stakes are high. A single mistake — wrong grade, delayed supply, or uncertified material
When sourcing alloy steel coils for refineries, power plants, or boilers, one wrong decision can cost crores in shutdown losses.
SA 387 Gr 22 Cl 2 is a 2.25% Chromium, 1% Molybdenum alloy steel plate under ASTM/ASME standards.
This makes it the preferred choice for refineries, petrochemical plants, and power generation industries.

| Property | Typical Value | Notes |
|---|---|---|
| Tensile Strength | 415–585 MPa | Strong under continuous heat & load |
| Yield Strength | ≥ 240 MPa | Higher than Gr 11, ensures safety margin |
| Elongation | 18–22% | Provides ductility for forming & fabrication |
| Impact Test (Cl 2) | 27J at -18°C | Higher notch toughness than Class 1 |
Class 2 designation ensures better impact toughness, making it reliable for critical high-pressure projects
| Element | Typical Range % | Function |
|---|---|---|
| Carbon (C) | 0.05–0.15 | Strength & hardness |
| Chromium (Cr) | 1.90–2.60 | High-temp oxidation & corrosion resistance |
| Molybdenum (Mo) | 0.87–1.13 | Creep resistance, thermal stability |
| Manganese (Mn) | 0.30–0.60 | Improves toughness & ductility |
| Silicon (Si) | 0.50–1.00 | Enhances oxidation resistance |
| Phosphorus (P) | ≤ 0.025 | Low for weldability |
| Sulfur (S) | ≤ 0.010 | Low for crack resistance |
This Cr-Mo alloy balance makes SA 387 Gr 22 Cl 2 one of the most dependable boiler & pressure vessel steels in the market.
SA 387 Gr 22 Cl 2 is specified under ASTM A387 / ASME SA387 for chromium-molybdenum alloy steel plates.
