Nickel 400, also known as Monel 400, is a nickel-copper alloy known for its excellent strength and corrosion resistance in various harsh environments. It contains approximately 63% nickel and 28-34% copper, with small amounts of iron, manganese, carbon, and silicon. Nickel 400 steel plates are highly valued in industries where durability, toughness, and resistance to corrosion are essential.

Excellent Corrosion Resistance: Resistant to many corrosive environments, including seawater, hydrofluoric acid, sulfuric acid, and alkaline solutions.
High Strength and Toughness: Maintains strong mechanical properties from sub-zero temperatures up to around 537°C (1000°F).
Good Weldability: Easily welded by conventional methods without the need for post-weld heat treatment.
Resistant to Pitting and Stress-Corrosion Cracking: Performs well in marine and chemical processing environments where these issues are common.
