| Iron (Fe) | 2.5 max |
| Manganese (Mn) | 2.0 max |
| Silicon (Si) | 0.5 max |
| Carbon (C) | 0.3 max |
Monel 400 Plate Price Comparison by Region
Global pricing varies depending on labor, quality, and logistics:
| Region | Average Price (USD/kg) | Notes |
|---|---|---|
| USA | $50 – $65 | High-quality, ASME and ASTM certified |
| Germany / EU | $52 – $67 | REACH and EN compliant |
| China | $38 – $52 | Cost-effective, often with ISO/ASTM certification |
| India | $40 – $55 | Large volume exporters, customizable sizes |
Monel 400 vs Stainless Steel Plate (304/316)
Monel 400 is more expensive but far superior in resistance to harsh chemicals and seawater:
| Property | Monel 400 | 304/316 Stainless Steel |
|---|---|---|
| Corrosion Resistance (Seawater) | Excellent | Good (316), Moderate (304) |
| Price per Kg (avg) | $48 – $60 | $2.5 – $4.5 |
| Weldability | Good | Excellent |
| Density | 8.8 g/cm³ | 7.9 g/cm³ |
Market Trends and Future Outlook (2025)
As of mid-2025, Monel 400 plate demand is rising due to:
• Increased demand from oil & gas and desalination projects.
• Nickel price volatility on the LME affecting base alloy prices.
• Preference for corrosion-resistant materials over conventional stainless steel.
• Stringent quality requirements increasing certified plate costs (e.g., NACE, ASME codes).
