Monel 400 (UNS N04400, ASTM B164) is a solid-solution nickel-copper alloy engineered for corrosion resistance to seawater, sulfuric acid, and hydrogen sulfide environments. Its nickel-copper matrix imparts superior resistance to chloride stress corrosion cracking while retaining ductility and weldability. The alloy offers tensile strength from about 480 MPa annealed, higher in cold-worked tempers, and continuous service to around 480°C, making it ideal for valves, pumps, compressors, subsea equipment, and heat exchangers in the harshest industrial settings.
Aurico Alloys LLP provides Monel 400 Sheets in multiple thicknesses and finishing options, with full ASTM certification and mill test reports ensuring global quality compliance. Our high availability and custom cutting capabilities support industrial OEMs, fabricators, and maintenance teams with rapid, reliable deliveries for critical projects.
Selecting Aurico’s Monel 400 Sheets means gaining assurance of long-term operational excellence, reduced downtime, and compliance with stringent chemical and marine standards. This material is a vital investment for safety-critical systems exposed to sour gas, saltwater, and aggressive chemical conditions.
High-quality Monel 400 Sheets ready for industrial use.
