Lean Duplex Stainless Steel 2101 (UNS S32101)
Lean Duplex Stainless Steel 2101 (UNS S32101)
Lean Duplex Stainless Steel 2101 (UNS S32101) is a high-strength, low-nickel duplex stainless steel grade engineered for excellent corrosion resistance and durability in moderately aggressive environments. With a balanced austenitic-ferritic microstructure, this grade offers superior resistance to stress corrosion cracking, pitting, and crevice corrosion while maintaining excellent weldability and formability. Its high strength-to-weight ratio makes it ideal for applications in chemical processing, marine, and water treatment industries.
At Apar Alloys, we are a trusted stockist and supplier of Lean Duplex 2101 (UNS S32101) materials, sourcing products from reputed global mills. Our inventory includes bars, sheets, plates, and round bars available in various sizes and finishes to meet diverse industrial requirements. Each product undergoes stringent testing and inspection to ensure consistent quality, reliability, and long-term performance.
