Monel 400 Nickel-Copper Alloy Forged Disc, ASTM B564 Standard, Excellent Corrosion Resistance for Marine and Chemical Applications

Monel 400 Nickel-Copper Alloy Forged Disc

Monel 400 (UNS N04400) forged disc is manufactured from nickel-copper alloy, offering excellent resistance to seawater, acids, and alkaline corrosion, along with good mechanical strength, toughness, and low-temperature performance. The hot forging process improves material density and structural uniformity, making it suitable for marine engineering, chemical processing equipment, oil & gas applications, and pressure components operating in highly corrosive environments.

Key Features

• Excellent corrosion resistance against seawater, saltwater, acids, and alkaline media.
• Good strength, toughness, and low-temperature performance for demanding service conditions.
• Dense forged structure with uniform grain distribution, providing high reliability and long service life.
• Excellent stress corrosion cracking resistance for highly corrosive environments.
• Good machinability, suitable for turning, milling, and precision machining operations.

Typical Applications

• Marine Engineering: Seawater pumps, valves, ship equipment, and desalination systems.
• Chemical Processing: Reactors, heat exchangers, pipelines, and corrosion-resistant pressure components.
• Oil & Gas: Sour service equipment, downhole tools, and components for corrosive environments.
• Energy Industry: Equipment parts and fittings used in high-temperature corrosive conditions.
• Industrial Machinery: Pump bodies, flanges, fasteners, and custom forged components.
