Marine Engineering Application Forged Flange

Monel 400 Forged Flange
Manufactured in accordance with ASTM B564 UNS N04400 from high-quality nickel-copper alloy billets, these forged flanges are engineered for exceptional resistance to seawater, hydrofluoric acid, and alkaline environments. As professional forging manufacturers, we produce heavy-wall and large-diameter Monel 400 flanges for demanding marine, offshore, and chemical processing systems where corrosion resistance and mechanical reliability are critical.
Material Advantages - Monel 400 Alloy
Monel 400 is a solid-solution alloy composed primarily of nickel and copper, making it highly resistant to a wide range of corrosive environments. It maintains outstanding strength, ductility, and stability under both cryogenic and elevated temperatures.
Main Characteristics:
  • Excellent corrosion resistance in marine and alkaline environments
  • High toughness and durability at both low and high temperatures
  • Resistance to stress corrosion cracking and cavitation
  • Suitable for hot forming, welding, and machining
Performance Advantages
  • Room Temperature Strength: Tensile strength approximately 30% higher than 304 stainless steel
  • Low-Temperature Toughness: Impact energy >75 J at -196°C, no brittle fracture risk; suitable for LNG storage and transportation equipment
  • High-Temperature Performance: Maximum continuous service temperature approximately 600°C in air; corrosion rate <0.026 mm/a in high-temperature steam
