Chanathip Nickel Alloys & Plates in Bangkok, Thailand, is a premium manufacturer of Duplex Steel coils. Our steel coils are produced in 2205 (S32205 / S31803) duplex stainless steel, hot-rolled and cold-rolled conditions, multiple widths, thicknesses and coil weights. We subject these coils to stringent heat treatment and surface finishing operations to guarantee corrosion resistance, dimensional stability, and metallurgical integrity. These coils are provided with certification and traceability and are used by customers in businesses such as chemical processing, marine, oil & gas, and infrastructure where high strength and excellent corrosion resistance are critical.

The Duplex Steel coils are utilized in production of sheets, plates, and strips which are further processed into equipment for chemical plants, marine applications, heat exchangers, and desalination systems.
They are utilized in salt water exposed environments, aggressive chemicals, and chloride‐rich atmospheres. Coil form facilitates low‐cost processing (slitting, cutting, forming) for mass production of flanges, pipe covers, structure panels, and parts in offshore, oil & gas, and water treatment applications. Thin sections are possible due to the high strength of 2205 duplex, lowering material cost while ensuring durability and resistance to corrosion. 2.
