Wuxi Yansheng Technology Co., Ltd., a leading manufacturer established in 2017 with a factory spanning 1,000–3,000 square meters and an annual export value between US$50 million and US$100 million, is proud to present our Nickel Alloy 25ht UNS N06696 Plate Sheet. This high-performance material is engineered for extreme high-temperature environments, offering exceptional strength, oxidation resistance, and structural stability. Our advanced production capabilities and strict quality control ensure that every plate and sheet meets the rigorous demands of industries such as aerospace, power generation, chemical processing, and industrial furnaces.
The Nickel Alloy 25ht (UNS N06696) is a solid-solution strengthened nickel-based alloy specifically formulated to maintain high mechanical properties at elevated temperatures up to 1100°C. Its unique composition provides excellent resistance to creep, thermal fatigue, and corrosion in harsh environments. Whether you need thin sheets for cladding or thick plates for structural components, our product offers consistent quality and reliable performance.
Key Features & Technical Specifications
Exceptional High-Temperature Strength: Maintains tensile strength above 620 MPa at room temperature and retains significant strength at 800°C, ensuring long service life under thermal stress.
Oxidation & Corrosion Resistance: The alloy forms a stable oxide layer that protects against scaling and corrosive attack in oxidizing, reducing, and carburizing atmospheres.
Excellent Creep Resistance: Low creep rate at elevated temperatures minimizes deformation under constant load, critical for turbine blades, furnace fixtures, and heat exchangers.
Good Fabricability: Can be welded, formed, and machined using standard techniques; suitable for hot and cold working processes.
Versatile Dimensions: Available in plate and sheet forms with thicknesses from 3mm to 100mm, widths up to 3000mm, and lengths up to 12000mm – all customizable to your specifications.
Surface Finishes: Options include hot rolled, cold rolled, pickled, or polished surfaces to meet different application requirements.

Detailed Product Advantages
The Nickel Alloy 25ht UNS N06696 plate/sheet is designed to outperform conventional stainless steels and nickel alloys in high-temperature applications. Its balanced chemical composition – including chromium, molybdenum, aluminum, and titanium – provides a unique combination of strength and environmental resistance. For example, in gas turbine components, the alloy resists thermal fatigue cracking; in furnace muffles, it withstands cyclic heating without warping; in chemical reactors, it offers protection against chloride stress corrosion cracking.
Our manufacturing process employs advanced hot rolling and controlled cooling to ensure uniform microstructure and consistent mechanical properties across the entire plate. Each coil or sheet undergoes ultrasonic testing, dimensional inspection, and surface quality checks before shipment. We also offer optional third-party inspection services (e.g., SGS, BV) to meet your project requirements.
Customization is a key advantage: we can supply plates/sheets with special edge preparations (e.g., beveled edges for welding), cut-to-size lengths, and tailored surface finishes. Whether you need a single prototype piece or bulk orders for large-scale projects, our flexible production capacity (101–200 skilled employees) ensures timely delivery from our factory in Wuxi, Jiangsu, China.

Frequently Asked Questions
What is the difference between Nickel Alloy 25ht and other UNS N06696 grades? – UNS N06696 is a standard designation for this specific alloy; “25ht” indicates a high-temperature optimized variant. Our product meets the same chemical requirements but with tighter control on trace elements for enhanced performance.
Can you provide material certificates (MTC) for each batch? – Yes, we supply mill test certificates (MTC) per EN 10204 3.1 or 3.2, including chemical composition, mechanical properties, and heat treatment details.
What is the minimum order quantity (MOQ) for plates/sheets? – For standard sizes, MOQ is 1 ton; for custom dimensions, please consult our sales team. We also accept trial orders for small quantities.
How do you ensure the flatness of thick plates? – We use roller leveling and stress-relief heat treatment to achieve flatness tolerances conforming to ASTM A480. For critical applications, we can perform additional flattening upon request.
Are these plates suitable for welding without preheating? – The alloy has good weldability, but for sections over 10mm, we recommend preheating at 150-200°C to prevent cracking. Please refer to our welding guide or request technical support.
What surface finishes are available for the sheets? – We offer No.1 (hot rolled), 2B (cold rolled, smooth), BA (bright annealed), and pickled finishes. Custom finishes like brushed or mirror polish are available on request.
How long does delivery typically take? – For standard products, delivery is 15-25 days after order confirmation. For custom dimensions or special treatments, lead time is 30-45 days, depending on quantity.
Can you supply this material for ASME Section VIII applications? – Yes, we can provide material certified to ASME BPVC Section II Part B, with appropriate documentation. Please specify your code requirements when ordering.
