Alloy 1.4482 / UNS S32101 Duplex Stainless Steel Plate / Sheet With Excellent Weldability and Durability

Alloy 1.4482 / UNS S32101 Duplex Stainless Steel Plate / Sheet With Excellent Weldability and Durability

Alloy 1.4482 (UNS S32101) is a lean duplex stainless steel that combines high mechanical strength with outstanding corrosion resistance. This alloy features a balanced microstructure of ferrite and austenite, offering twice the yield strength of conventional austenitic grades like 304L and 316L while maintaining good toughness and weldability.

Designed for structural and process applications, S32101 duplex stainless steel plate and sheet provide long-term performance in harsh environments, especially those exposed to chlorides, acids, or seawater. Its cost efficiency, mechanical stability, and easy fabrication make it a preferred choice across multiple industries.

Main Characteristics

• Superior Weldability: Supports all standard fusion welding methods without preheating or post-weld heat treatment.

• Enhanced Durability: High resistance to fatigue, erosion, and stress corrosion cracking.

• Corrosion Resistance: Performs well in acidic and chloride-rich media.

• High Strength-to-Weight Ratio: Allows for lighter designs and reduced material consumption.

• Eco-Friendly Composition: Low nickel and molybdenum content for sustainable, cost-effective production.
