Product Description:
2101 Duplex Stainless Steel Sheets, also known as UNS S32101, are high-strength, low-alloy duplex stainless steel sheets designed for applications requiring excellent mechanical properties and good corrosion resistance. These sheets are an economical alternative to traditional austenitic stainless steels, offering superior performance in various environments.
Key Features of 2101 Duplex Stainless Steel Sheets
- High Strength: Approximately twice the yield strength of 304 and 316 stainless steels.
- Cost-Effective: Lower nickel and molybdenum content make it more economical compared to other stainless steels.
- Corrosion Resistance: Excellent resistance to stress corrosion cracking, pitting, and crevice corrosion.
- Durability: Exceptional toughness and fatigue resistance.
- Environmentally Friendly: Lower alloy content reduces environmental impact during production.
