What Are Monel 400 Plates and Sheets?
Monel 400 Sheet & Plate is a plate of copper-nickel base alloy. With these, it is being traced with the volume of manganese, silicon content, and carbon. Such Alloy 400 plates are very ductile and enable them to endure best against a wide spate of corrosive environments. These plates are alkaline and environmentally resistant. Nevertheless, it has high thermal conductivity under annealed states. High tensile strength and toughness are contained in this grade of plates. In addition, they are applicable in low temperatures as low as 1000°F. In this way good hardness is obtained in these plates through cold working.
The model 400 plates and sheets are stress corrosion crack and pitting corrosion resistant. It is hence resistant to marine conditions, but these are produced in cold and hot rolled conditions.
