We offer high-performance alloy materials including Inconel, Monel, Hastelloy, Nickel, and Duplex, with all products compliant with ASTM/ASME international standards. Through precise chemical composition control and full-thickness performance consistency assurance, our products meet diverse industrial needs—from aerospace hot-end components and deep-sea corrosive environments to chemical reaction vessels and new energy equipment. Coil form is particularly suitable for continuous automated production scenarios, supporting efficient stamping, forming, and welding processes. While maintaining excellent corrosion resistance, high-temperature strength, and fatigue resistance, our coils significantly enhance the economic efficiency of our customers' production workflows.

Starting from the selection of high-purity nickel ingots, we achieve component homogenization through vacuum induction melting, followed by hot rolling for billet opening and multi-pass cold rolling to precisely control thickness. Key processes adopt online thickness monitoring and temperature closed-loop control systems, ensuring rolling accuracy error is ≤ ±0.01mm. After cold rolling, continuous solution treatment (800-1150℃) is performed to eliminate processing stress, and surface treatments such as degreasing and passivation are applied to enhance corrosion resistance. Finally, precise slitting, constant-tension winding, and non-destructive testing are conducted. The entire process complies with ASTM/AISI standards, ensuring every nickel alloy coil possesses consistent performance and appearance.

The manufacturing process utilizes a fully automated intelligent control system with digital monitoring from raw material pretreatment through continuous rolling and annealing treatment. Equipped with German-engineered 4-high reversible rolling mills and continuous annealing furnaces, we ensure consistent mechanical properties throughout each coil. Online non-destructive testing equipment provides real-time surface defect and microstructure inspection, while precision slitting units guarantee perfect coiling flatness. Our ISO9001-certified production involves 16 quality checkpoints from molten steel to finished products, ensuring uncompromising quality throughout the entire manufacturing process.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
