Introduction to Monel 400 Sheets

Monel 400 sheets are highly sought after in marine and industrial applications due to their exceptional corrosion resistance, strength, and durability. As a nickel-copper alloy, Monel 400 exhibits superior performance in harsh environments, particularly in seawater and chemical processing industries.

Material Overview

Monel 400 (UNS N04400) is a solid-solution alloy primarily composed of nickel and copper, with trace amounts of iron, manganese, carbon, and silicon. This composition grants it excellent resistance to various forms of corrosion, including pitting, crevice corrosion, and stress corrosion cracking.

Chemical Composition:

• Nickel (Ni): 63.0% minimum

• Copper (Cu): 28.0-34.0%

• Iron (Fe): 2.5% maximum

• Manganese (Mn): 2.0% maximum

• Silicon (Si): 0.5% maximum

• Carbon (C): 0.3% maximum

• Sulfur (S): 0.024% maximum

Properties of Monel 400 Sheets

• High corrosion resistance: Excellent performance in marine, acidic, and alkaline environments.

• Superior mechanical properties: High strength and toughness even at elevated temperatures.

• Excellent thermal conductivity: Effective for heat exchangers and condenser applications.
