Monel Sheet
Stellanox Steel is a trusted supplier of premium-grade Monel Sheets manufactured to withstand marine, chemical, and high-temperature environments. Engineered from corrosion-resistant nickel-copper alloys like Monel 400 and Monel K500, our sheets deliver superior performance in seawater, acids, alkalis, and salt-laden atmospheres.
Available in a variety of finishes, thicknesses, and dimensions, Monel sheets are widely used in heat exchangers, marine fabrication, chemical storage, and oil & gas systems.
What are Monel Sheets?
Monel Sheets are flat-rolled products made from nickel-copper alloys known for their excellent mechanical strength, corrosion resistance, and workability. Unlike stainless steels, Monel maintains structural integrity even in acidic and saline environments, making it ideal for components that face continuous exposure to moisture, heat, and corrosive chemicals.
Monel 400 is the most common grade used in sheet form due to its versatile corrosion resistance and mechanical durability.
