Alloy 800 800H800HT(UNS N08800) Nickel Alloy Steel Plate

Our comprehensive range of Alloy 800 / 800H / 800HT (UNS N08800, N08810, N08811) nickel alloy plates is designed to provide reliable material solutions for the most demanding applications in high-temperature and corrosive environments. Manufactured to international standards through hot rolling processes, these plates ensure exceptional metallurgical integrity, uniform mechanical properties, and superior resistance to oxidation, carburization, and sulfidation. Our Alloy 800 series plates cater to industries ranging from petrochemical processing and heat treating equipment to power generation, industrial furnaces, and waste heat recovery systems. Whether you require heavy plates for pressure vessels, furnace components, heat exchanger parts, or precision-cut blanks for high-temperature fabrication, our products deliver dimensional accuracy, surface quality, and consistent performance at elevated temperatures.

OEM & Custom Services

We understand that standard sizes cannot cover all project needs. Our OEM customization services allow you to tailor nickel alloy plates and sheets to your exact specifications:

Custom Cutting:

Laser cutting, water-jet cutting, or shearing to precise shapes and dimensions as per your drawings.

Heat Treatment:

Custom heat treatment cycles to achieve specific mechanical properties and microstructures. Alloy 800 series plates are typically supplied in the solution annealed condition. For 800H and 800HT grades, controlled annealing is critical to achieve the required coarse grain size for optimal creep resistance at high temperatures.

Edge Preparation:

Machined edges, beveled edges for welding preparation, or debarred edges for safe handling.

Forming Services:

Rolling into cylinders, bending, or flattening as per your requirements.

Custom Packaging:

 

Plywood cases for small sheets, steel-framed crates for large plates, with protective inter-layers and custom labeling for inventory management.
