Monel Sheets

Nickel-Copper Alloy Sheets Built for Superior Seawater & Chemical Resistance

RSD’s Monel Sheets are made from a high-strength nickel-copper alloy designed for tough, corrosive environments. Monel is especially effective in saltwater and acidic conditions, making it a go-to material for marine, chemical, and oil refining applications.

Highly resistant to corrosion, erosion, and caustic environments, Monel Sheets are also non-magnetic and spark-resistant, making them ideal for sensitive or hazardous zones. Whether you’re manufacturing heat exchangers or pump shafts, Monel ensures durability and reliability where it matters most.

Grades & Specifications

  • Available Grades:
    • Monel 400 (UNS N04400)
    • Monel K500 (UNS N05500)
  • Thickness Range: 0.5 mm – 50 mm
  • Width & Length: Standard and custom cut-to-size options
  • Standards: ASTM B127, ASME SB127
  • Available Finishes: 2B, No.1, hot rolled, pickled, annealed

Key Features & Benefits

Exceptional Corrosion Resistance in Saltwater: Monel Sheets resist rapid corrosion and pitting in seawater, making them ideal for marine and shipbuilding applications. Acid and Alkali Resistance: Monel performs well in acidic and alkaline media, including hydrofluoric acid, sulfuric acid, and caustic soda where stainless steel would fail. High Strength and Toughness: Retains strength at both sub-zero and elevated temperatures. K500 variant offers even higher tensile and yield strength due to age-hardening. Non-Magnetic & Spark-Resistant: Safe for use in explosive environments or near sensitive instrumentation. Excellent Workability: Monel can be welded, brazed, and formed using conventional processes, allowing for design flexibility across industries.

Common Applications

Monel Sheets are commonly used in:
  • Marine Engineering: Propeller shafts, seawater valves, fasteners, piping systems, and hull cladding.
  • Oil & Gas Industry: Refinery equipment, off-shore rigs, and oil well tools exposed to brine and sulfide gases.
  • Chemical Processing Plants: Heat exchangers, evaporators, acid storage tanks, and processing vessels.
  • Power Generation: Condensers and feedwater heaters in steam and nuclear power plants.
  • Aerospace & Defense: Fuel tanks, hydraulic lines, and structural components requiring corrosion immunity.
