Product Summary
Ni200 pure nickel plate is a commercially pure wrought nickel material with a minimum nickel content of 99.0%. Engineered for severe chemical and thermal processing environments, this 5mm hot rolled pure nickel heavy plate delivers outstanding resistance to reducing acids, caustic alkalis, and anhydrous hydrogen fluoride. Designed specifically for chemical reactor cladding, pressure vessel fabrication, and industrial heat exchangers, our Ni200 plates feature uniform grain structure, excellent thermal conductivity, low gas content, and superior ductility for seamless forming and welding. With an integrated manufacturing facility and strict ultrasonic testing, we provide custom cutting, surface finishing, and full material traceability.
Product Overview
Commercially pure nickel 200 is an unalloyed solid solution strengthened material offering superior mechanical toughness, magnetic characteristics, and high thermal and electrical conductivity across a wide temperature spectrum. In industrial reactor vessel lining and cladding applications, solid or clad Ni200 5mm hot rolled plates provide an impenetrable corrosion barrier against sodium hydroxide, dry chlorine, and organic chloride media up to 315 degrees Celsius.
Our hot rolling process ensures optimal mechanical integrity, isotropic tensile properties, and freedom from internal lamination or voids. Each plate undergoes controlled annealing to achieve a uniform hardness of 90 to 120 HB, ensuring effortless cold bending, rolling into vessel shells, and defect-free welding with matching nickel filler metals.

Product Features and Technical Advantages:
Superior Resistance to Caustic Alkalis and Halogen Media Ni200 pure nickel plate demonstrates virtually zero corrosion rate in boiling sodium hydroxide and potassium hydroxide solutions at all concentrations. It forms a dense, tenacious protective oxide film that prevents stress corrosion cracking in aggressive chlorination and fluorination environments.
Heavy Duty Hot Rolled Mechanical Integrity The 5mm hot rolled structure delivers high impact toughness, uniform elongation, and low residual stress. It withstands severe thermal cycling and pressure fluctuations inside high-pressure reactors and autoclaves without embrittlement.
Exceptional Thermal and Electrical Conductivity With thermal conductivity significantly higher than austenitic stainless steels and nickel-chromium alloys, Ni200 ensures rapid, uniform heat transfer across vessel walls, optimizing chemical reaction efficiency and preventing localized thermal hotspots.
Outstanding Fabricability and Weldability Supplied in the annealed condition with a balanced 90 to 120 HB hardness, our Ni200 plates can be readily cold formed, dished into vessel heads, sheared, and welded using TIG, MIG, and submerged arc welding techniques without post-weld heat treatment.
Product Applications:
Chemical Reactor Cladding and Pressure Vessels Used as protective interior liners, explosion-bonded cladding backings, and solid vessel walls for synthesis reactors handling caustic soda, synthetic fibers, and chlorinated organics.
Caustic Soda Evaporators and Chlorine Processing Primary structural and lining material for multi-effect caustic evaporators, diaphragm cell headers, chlorine drying towers, and anhydrous hydrogen fluoride piping systems.
Fluorine Generation and Nuclear Engineering Crucial component for fluorine electrolytic cells, isotope separation equipment, and specialized heat transfer systems requiring complete immunity to dry fluorine gas attack.
Petrochemical and Catalyst Production Equipment Fabrication of catalyst regeneration vessels, hydrogenation columns, fatty acid processing kettles, and high-purity organic chemical storage tanks.
Electronics and Battery Energy Systems Heavy busbars, high-current lead connectors, and molten salt energy storage vessel components requiring ultra-low electrical resistivity and high thermal stability.

Product FAQ
Q1: What is the primary difference between Ni200 and Ni201 pure nickel plates?
A1: Ni200 contains up to 0.15% carbon, making it suitable for service temperatures up to 315 degrees Celsius. For operating temperatures exceeding 315 degrees Celsius, low-carbon Ni201 (carbon content capped at 0.02%) is recommended to prevent intergranular graphitization and embrittlement.
Q2: Can this 5mm hot rolled Ni200 plate be welded directly to carbon steel backing plates for cladding?
A2: Yes. Ni200 plates are widely used for explosion bonding, hot roll bonding, and weld overlay cladding on carbon steel or low alloy steel substrates. Matching pure nickel or nickel-copper transition welding consumables are typically used for joinery.
Q3: What surface finishes and edge preparation options are available?
A3: We supply hot rolled pickled and descaled surfaces, sandblasted surfaces, and precision polished finishes. Edges can be mill edge, sheared, saw cut, CNC waterjet cut, or beveled for direct weld preparation.
Q4: What is your standard lead time, MOQ, and sample policy?
A4: Our standard MOQ is 5 kg for standard stock specifications, and we provide 0.5 kg free material samples for laboratory and corrosion validation. Standard stock plates ship within 3 to 7 working days, while custom rolling schedules take approximately 15 to 20 working days.
Q5: What inspection documents are provided with the shipment?
A5: Every shipment includes an official Mill Test Certificate detailing 100% verified chemical composition, tensile and yield strength, elongation, Brinell hardness, and ultrasonic testing compliance.
