UNS S32205 Stainless Steel Plate is mainly composed of iron, chromium, nickel, molybdenum, manganese, nitrogen and other elements. The typical chemical composition content is roughly:

• Chromium (Cr): 21-23%
• Nickel (Ni): 4.5-6.5%
• Molybdenum (Mo): 2.5-3.5%
• Manganese (Mn): maximum 2.0%
• Carbon (C): maximum 0.03%
• Nitrogen (N): 0.08-0.2%
• Silicon (Si): maximum 1.0%
• Phosphorus (P): maximum 0.03%
• Sulfur (S): maximum 0.02%

Good corrosion resistance: Excellent performance in a variety of corrosive environments, especially in chloride-containing environments such as seawater, chemical liquids, etc., with high resistance to pitting and stress corrosion. Its corrosion resistance is better than that of fully austenitic 304, 316 and 317L stainless steels. UNS S32205 Stainless Steel Plate has excellent resistance to sulfuric acid, phosphoric acid, nitric acid and many other acids and salts, and also has high resistance to acetic acid, formic acid and other organic acids and compounds.

High strength: It has high yield strength and tensile strength, and good toughness. The yield strength is typically a minimum of 65,000psi (about 448MPa) and the tensile strength is a minimum of 90,000psi (about 621MPa). This high strength makes it suitable for applications requiring higher strength and corrosion resistance, such as offshore platform structures, oil drilling equipment and chemical pressure vessels.

Duplex structure: It has both austenite and ferrite structures, which provides good corrosion resistance and stress corrosion resistance while maintaining good weldability and processing properties.

Good welding performance: It can easily handle both manual welding and automated welding, and can be welded by conventional welding methods. The strength and sealing of the joints after welding are excellent.

Including raw material preparation, smelting, continuous casting, heating treatment, rolling, pickling, cold rolling, annealing, cutting, surface treatment and inspection and quality control. The specific process may vary according to production and product requirements.

Very wide, including:

• Chemical industry
