Monel 400 Plate: Unmatched Corrosion Resistance and High-Temperature Stability for Industrial Excellence
Description
Monel® 400 Plate, a nickel-copper alloy (UNS N04400/EN 2.4360), is engineered to deliver unparalleled performance in the most demanding industrial environments. With a composition of 63–70% nickel, 28–34% copper, and controlled trace elements (Fe ≤2.5%, Mn ≤2%, C ≤0.3%, Si ≤0.5%), this alloy combines exceptional corrosion resistance with robust mechanical strength. Monel 400 Plate excels in resisting chloride-induced stress corrosion cracking, hydrofluoric acid, sulfuric acid, and alkaline solutions, outperforming conventional stainless steels in marine, chemical, and high-temperature applications. Its single-phase solid-solution structure ensures stability up to 600°C, with tensile strength of 480–550 MPa, yield strength of 170–240 MPa, and elongation of 35–45%. Cold-rolled (CR) variants achieve enhanced hardness, while hot-rolled (HR) plates maintain superior ductility for forming and welding. Compliant with ASTM B127, ASME SB127, and EN standards, Monel 400 Plate is the material of choice for critical infrastructure, from offshore platforms to nuclear reactors, where reliability and longevity are non-negotiable.

Key Applications of Monel 400 Plate
Marine Engineering: Offshore platform components, seawater heat exchangers, and desalination systems resistant to biofouling and saltwater corrosion.
Chemical Processing: Reactors, HCl storage tanks, and sulfuric acid handling equipment withstanding aggressive media.
Oil & Gas: Crude distillation units, sour gas pipelines, and downhole tools in high-chloride environments.
Nuclear Power: Steam generator tubing and reactor coolant systems requiring radiation resistance.
Aerospace: High-temperature actuator components and rocket engine parts exposed to thermal cycling.
Monel 400 Plate: Frequently Asked Questions
Q1: How does Monel 400 Plate compare to stainless steel 316L in marine environments?
A: Monel 400’s nickel-copper matrix reduces chloride-induced pitting by 80%, with corrosion rates <0.025 mm/year in seawater, outperforming 316L in long-term offshore applications.
Q2: Can Monel 400 Plate withstand welding without losing corrosion resistance?
A: Yes. TIG welding with AWS A5.11 ENi-7 electrodes and post-weld annealing at 825°C preserves microstructure integrity and corrosion resistance.
Q3: What thickness range is available for high-pressure applications?
A: Plates up to 100 mm thick meet ASME BPVC Section VIII requirements for pressures exceeding 50 MPa at 300°C.
Q4: Is Monel 400 suitable for sulfuric acid concentrations above 70%?
A: At ambient temperatures, it resists up to 85% H2SO4, with corrosion rates <0.1 mm/year, ideal for acid production units.
Q5: Are certified traceability documents provided?
A: Full Mill Test Certificates (MTC) with PMI verification and third-party inspection reports ensure compliance with global standards.
