Monel 400 Bars and Rods are prized for their remarkable resistance to corrosion, especially in seawater and both acidic and alkaline environments, making them perfect for tough industrial applications. This nickel-copper alloy not only boasts impressive toughness but also offers excellent thermal conductivity and dependable performance across a broad temperature spectrum. These bars and rods hold their strength even in the most challenging, corrosive, or high-pressure situations. Thanks to their outstanding durability, ease of fabrication, and resistance to stress cracking, Monel 400 is a go-to choice in marine, chemical processing, oil and gas, and engineering fields that demand long-lasting, high-performance materials.
Made up primarily of nickel (about 63%) and copper, with trace amounts of iron, manganese, and silicon, Monel 400 provides exceptional resistance to seawater, hydrofluoric acid, and caustic solutions. It has a tensile strength ranging from 480 to 620 MPa and a yield strength between 170 and 345 MPa, depending on its condition. The alloy is known for its remarkable toughness, good ductility, and excellent thermal and electrical conductivity. Its non-magnetic properties and stability at both low and high temperatures further enhance its adaptability for critical applications.
