Product Description:
2101 Duplex Stainless Steel Plates, also referred to as UNS S32101, are an advanced duplex stainless steel option combining high strength, excellent corrosion resistance, and cost efficiency. These plates are ideal for applications demanding superior performance in challenging environments.
Key Features of 2101 Duplex Stainless Steel Plates
- High Strength: Offers twice the yield strength of traditional austenitic grades like 304 and 316.
- Cost-Effective: Low nickel and molybdenum content make it an economical alternative to other stainless steels.
- Corrosion Resistance: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich environments.
- Durable and Tough: Excellent fatigue resistance and toughness, even in cryogenic conditions.
- Sustainable: Lower alloy content reduces the environmental impact of production.
