Navgraha SteelsINC supplies 16Mo3 Plates, Sheets & Coils from top international mills like Sail, AMNS, JSPL, Evonith, Nippon Yakin, Outokumpu, Special Metals, VDM, and ATI. A widely used EN 10028-2 pressure vessel grade, 16Mo3 is designed for boilers, refinery vessels, and high-temperature equipment. Every delivery is supported with EN 10204 3.1/3.2 MTCs, IBR approvals, and third-party inspections for compliance in global projects.
In EPC projects, one wrong steel grade can cost millions. Boiler plates like 16Mo3 aren’t just metal sheets
When you’re sourcing boiler and pressure vessel steel sheets, there is no margin for error.
When you’re responsible for sourcing boiler and pressure vessel materials, a wrong delivery can mean shutdown delays
16Mo3 is a Cr-Mo alloy pressure vessel steel with 0.3% molybdenum that provides excellent strength, heat resistance, and corrosion resistance at elevated temperatures.
It is often selected as the European equivalent to ASTM SA 387 Gr 12 Cl 2.

where EN-based compliance is required
| Property | Typical Value | Notes |
|---|---|---|
| Tensile Strength | 440–590 MPa | Good for moderate-high stress service |
| Yield Strength | ≥ 220 MPa | Ensures structural safety |
| Elongation | 19–23% | High ductility for forming |
| Impact Test | 27J at -20°C | Excellent notch toughness |
Provides strength + toughness balance for long service in boilers & vessels.
| Element | Typical Range % | Function |
|---|---|---|
| Carbon (C) | 0.12–0.20 | Strength & hardness |
| Manganese (Mn) | 0.40–0.90 | Improves toughness & weldability |
| Silicon (Si) | 0.35 max | Oxidation resistance |
| Phosphorus (P) | ≤ 0.025 | Low for weldability |
| Sulfur (S) | ≤ 0.010 | Low for crack resistance |
| Chromium (Cr) | 0.30 max | Corrosion resistance |
| Molybdenum (Mo) | 0.25–0.35 | Improves creep strength |
Its Mo-enhanced chemistry allows stable performance in high-pressure, high-heat service.
16Mo3 is specified under EN 10028-2 for weldable pressure vessel steels for elevated temperature service.
