Chanathip Nickel Alloys & Plates is a specialized manufacturer of high-performance Duplex Steel S32205 Sheets and Plates in Bangkok, Thailand. In different thicknesses and sizes as per customer specifications, our S32205 plates are manufactured according to ASTM A240 standards. These possess high strength, superior corrosion resistance, and good workability. We use sophisticated cutting, surface treatment, and inspection techniques to assure the best delivery for structural and pressure-service uses. Our S32205 duplex plates are utilized in offshore, petrochemical, chemical, and water treatment industries that demand reliability under harsh environments.
Duplex Steel S32205 has 22% chromium, 5–6% nickel, 3% molybdenum, and 0.20% maximum nitrogen. Duplex phase structure provides higher strength and corrosion resistance. S32205 provides yield strength ≥450 MPa, tensile strength 620–700 MPa, elongation ≥25%, and hardness less than 290 HB. It resists pitting caused by chlorides, crevice corrosion, and stress corrosion cracking. The alloy has good mechanical properties even after thermal cycling, with durability and structural stability. It is also resistant to welding-induced intergranular corrosion and is therefore suitable for fabricated parts.

S32205 Duplex Steel Plates and Sheets find applications in pressure vessels, marine structures, tanks, offshore drilling platforms, and desalination plants. Due to their resistance against seawater and chloride-induced corrosion, they are best suited for coastal infrastructure and chemical pipelines for transportation. These plates are also commonly used in heat exchangers, scrubbers, digesters, and evaporators. Due to their strength, they provide weight and cost savings in construction and equipment production. S32205 plates provide durability and minimal maintenance in harsh environments such as wastewater treatment plants, oil refineries, and food processing systems.
