As a leading manufacturer from Wuxi Yansheng Technology Co., Ltd., we are proud to present our High Performance Nickel Alloy 400 Plate Sheet, engineered specifically for the most demanding corrosion resistant applications. With over 7 years of expertise in the metal industry and a factory spanning 1,000-3,000 square meters, we combine advanced production technology with strict quality control to deliver plates and sheets that meet international standards. Our Nickel Alloy 400 (Monel 400) products are trusted by clients across North America, Europe, Southeast Asia, and beyond, serving industries that require exceptional resistance to acidic and alkaline environments, seawater, and high-temperature oxidation.
This alloy offers a unique balance of mechanical strength and corrosion resistance, making it the preferred choice for heat exchangers, chemical reactors, marine valves, and piping systems. Our plates and sheets are available in a wide range of thicknesses, widths, and lengths, with customizable surface finishes to suit your specific fabrication needs. Whether you require hot-rolled plates for structural components or cold-rolled sheets for precision parts, we provide consistent quality and reliable lead times.
Key Features & Technical Specifications
- Superior Corrosion Resistance: Excellent performance in reducing acids, hydrofluoric acid, and chloride environments. Resists pitting and crevice corrosion in seawater.
- High Strength & Toughness: Maintains mechanical properties at both cryogenic and elevated temperatures (up to 600°C).
- Excellent Weldability & Fabricability: Can be welded, brazed, and soldered using standard methods without post-weld heat treatment.
- Versatile Surface Options: Available in hot-rolled, cold-rolled, 2B, BA, No.1, mirror, and pickled finishes.
- Precise Dimensional Tolerances: Manufactured to ASTM B127 and ASME SB127 standards with tight thickness and flatness control.

Our Nickel Alloy 400 plates and sheets offer distinct advantages over stainless steels and other nickel alloys in corrosive environments. For example, in hydrofluoric acid production, Monel 400 outperforms Hastelloy and 316L due to its resistance to fluoride ions. In marine applications, it provides long service life without sacrificial anodes. Additionally, the alloy's low magnetic permeability makes it suitable for electronic and instrumentation enclosures.
We understand that every project has unique requirements. That's why we offer custom cutting, shearing, and surface finishing services to deliver exactly what you need. Our inventory includes standard sizes as well as custom dimensions with fast turnaround times. All products undergo rigorous inspection including chemical analysis, mechanical testing, and ultrasonic examination to ensure compliance with specifications.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between Nickel Alloy 400 and Monel 400?
A: They are the same material. Monel 400 is the trade name for alloy UNS N04400, which contains approximately 63% nickel and 28-34% copper. Our plates and sheets are manufactured to identical specifications. -
Q: Can you provide custom sizes and thicknesses?
A: Yes, we offer customization. You can specify thickness from 0.5mm to 100mm, width up to 3000mm, and length as required. We also provide cutting, slitting, and surface finishing services. -
Q: What certifications do your products have?
A: Our manufacturing facility is certified under ISO9001, ISO14001, OHSAS18001, and SA8000. Each shipment is accompanied by a Material Test Certificate (MTC) and can include third-party inspection reports if requested. -
Q: Is this alloy suitable for seawater applications?
A: Absolutely. Nickel Alloy 400 is widely used in marine environments including propeller shafts, pumps, and valves due to its excellent resistance to chloride-induced stress corrosion cracking and pitting in seawater. -
Q: What surface finishes are available?
A: We offer hot rolled (HR), cold rolled (CR), 2B (bright), BA (bright annealed), No.1 (hot rolled and annealed), mirror polish, and pickled finishes. The choice depends on your application and aesthetic requirements. -
Q: What is the typical lead time for standard sizes?
A: For standard thicknesses (2mm-20mm) and widths (1250mm/1500mm), lead time is usually 7-15 days after order confirmation. Custom orders may require 15-25 days depending on specifications. -
Q: Do you offer samples for testing?
A: Yes, we can provide small samples (e.g., 200x200mm) at a nominal cost. Shipping is at the buyer's expense. Samples are typically cut from production stock and represent the same quality as bulk orders. -
Q: How do you ensure the quality of the plates?
A: We perform chemical analysis using spectrometers, mechanical testing (tensile, yield, elongation, hardness), and ultrasonic inspection for internal defects. Each plate is marked with heat number and grade for traceability.
