Navgraha Steels INC supplies SA 387 Gr 12 Cl 2 Plates, Sheets & Coils manufactured by leading global mills such as Sail, AMNS, JSPL, Evonith, Nippon Yakin, Outokumpu, Special Metals, VDM, and ATI. This Chrome-Moly alloy steel grade is designed for boilers, heat exchangers, and medium-pressure vessels that operate at moderate high-temperature conditions. Every supply comes with EN 10204 3.1/3.2 MTCs, IBR approvals, and optional NACE compliance for critical industries.
When sourcing boiler-quality alloy steel plates, every decision carries risk. A wrong grade, delayed shipment, or uncertified supply can result
When it comes to boiler and pressure vessel materials, one wrong purchase can mean shutdown losses, non-compliance penalties, or failed safety audits.
When you’re sourcing alloy steel coils for boilers or refinery shutdowns, the risks are high.
SA 387 Gr 12 Cl 2 is a 1% Chromium, 0.5% Molybdenum alloy steel plate with balanced strength and temperature resistance.
It is often chosen for refineries, chemical plants, and boiler manufacturers requiring durability at moderate temperatures.

cost-effective Chrome-Moly solution for mid-range duty
| Property | Typical Value | Notes |
|---|---|---|
| Tensile Strength | 485–620 MPa | Reliable strength for moderate service |
| Yield Strength | ≥ 275 MPa | Ensures durability under medium stress |
| Elongation | 18–22% | Provides ductility for fabrication |
| Impact Test (Cl 2) | 27J at -18°C | Good notch toughness |
Class 2 ensures improved impact toughness, making it suitable for critical mid-temperature equipment.
| Element | Typical Range % | Function |
|---|---|---|
| Carbon (C) | 0.08–0.15 | Adds strength & hardness |
| Chromium (Cr) | 0.80–1.25 | Provides oxidation resistance |
| Molybdenum (Mo) | 0.44–0.65 | Improves creep resistance |
| Manganese (Mn) | 0.30–0.60 | Enhances ductility & toughness |
| Silicon (Si) | 0.20–0.50 | Boosts oxidation resistance |
| Phosphorus (P) | ≤ 0.025 | Kept low for weldability |
| Sulfur (S) | ≤ 0.010 | Low for crack resistance |
Its Cr-Mo chemistry provides a balance of strength, oxidation resistance, and cost-effectiveness for industrial applications.
