Monel 400 Coil

Overview & Core Advantages

Monel Alloys are high-performance nickel-copper alloys (comprising approximately 67% Nickel and 30% Copper). As one of the most versatile corrosion-resistant alloys in industrial use, the Monel series is indispensable in marine engineering, chemical processing, and the oil and gas sectors.

Why Choose Monel Alloys?

Superior Corrosion Resistance: Exceptional performance in hydrofluoric acid, fluorine gas, hot concentrated alkali solutions, and seawater.
Zero Stress Corrosion Cracking (SCC): Virtually immune to chloride-ion stress corrosion cracking in most environments.
Wide Temperature Range: Maintains high mechanical strength from sub-zero temperatures up to $480^circtext{C}$ ($900^circtext{F}$).
Excellent Workability: High suitability for machining, welding, and thermoforming.

Monel 400: The Corrosion-Resistant Standard

Monel 400 is a solid-solution alloy that can only be hardened by cold working. It is the "workhorse" of the series.

Key Applications: Marine heat exchangers, desalination units, salt production equipment, and sulfuric/hydrochloric acid environments.
Keywords: Monel 400 plate, Nickel-Copper 400, hydrofluoric acid resistant alloy.
