Sandvik SAF 2205 Plate, Sheet and Coil Product Information -:- For detailed product information, please contact sales. -: # **Product Name: Sandvik SAF 2205 Plate, Sheet and Coil (UNS S32205 / EN 1.4462)** ## **Introduction** Sandvik SAF 2205 in Plate, Sheet, and Coil forms represents the **industry-standard workhorse for fabricated structures, pressure vessels, and processing equipment** requiring a superior combination of strength and corrosion resistance. These product forms offer the full performance of premium duplex stainless steel in formats optimized for **cutting, forming, welding, and assembly**. With **over double the yield strength of standard austenitic grades like 316L**, SAF 2205 plate, sheet, and coil enable thinner sections, weight savings, and enhanced durability in aggressive environments prone to chloride stress corrosion cracking, pitting, and erosion. ## **Key Features** * **High Strength for Design Efficiency:** Yield strength (≥ 500 MPa) allows for **significant reduction in material thickness** for pressure vessels, tanks, and structural components, leading to weight savings and cost reduction. * **Superior Corrosion Resistance:** Provides excellent resistance to chloride stress corrosion cracking (SCC), pitting, and crevice corrosion, with a guaranteed PREN ≥ 34, making it ideal for chemical, marine, and offshore applications. * **Excellent Fabricability:** Designed for reliable **welding, hot and cold forming, and machining** using industry-standard practices. Compatible with the full range of standard fabrication techniques. * **Proven Performance & Consistency:** Sandvik's stringent production controls ensure uniform chemistry, microstructure, and mechanical properties across the entire coil or plate, guaranteeing predictable performance in fabrication and service. --- ## **1.

For coil, specify grade, thickness, width, and condition (e.g., A&P Coil). 2. **Condition & Heat Treatment:** Material is supplied in the **solution annealed and quenched condition**, typically followed by pickling to remove scale. This condition is mandatory for optimal corrosion resistance and must be preserved during fabrication. 3. **Fabrication & Welding:** * **Forming:** Requires higher forces than austenitic grades. Minimum bend radii should be respected. * **Welding:** Use qualified procedures with matching or over-alloyed duplex filler metals (e.g., ER2209). Strict control of heat input and interpass temperature is critical to avoid harmful phase precipitation in the heat-affected zone (HAZ). 4. **Certification:** Require a **Sandvik Mill Test Certificate (MTC/CMTR)** for each heat/lot, including full chemical analysis, mechanical properties (longitudinal and transverse), and impact test results. For pressure vessel use, the MTC must be ASME compliant. 5. **Quality Supplements:** For critical applications, additional testing such as **Ultrasonic Testing (UT)** for plate integrity, **Ferrite Measurement** (target ~40-60%), and **Intergranular Corrosion (IGC) testing** may be specified. -:- For detailed product information, please contact sales. -: Sandvik SAF 2205 Plate, Sheet and Coil Specification Dimensions Size： Diameter 20-1000 mm Length <7297 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Sandvik SAF 2205 Plate, Sheet and Coil Properties -:- For detailed product information, please contact sales. -:
