Lean Duplex Steel 2101 / UNS S32101 Plates / Sheets

Unimix Metals Cooperation is a top manufacturer, exporter, and supplier of high-quality Lean Duplex Steel 2101 Sheets, Plates, and Coils, also known as 2205 steel, which is the most commonly used duplex (ferritic/austenitic) stainless steel grade.Our UNS S32101 Hot Rolled Plates are highly valued for their excellent corrosion resistance and high strength. They are crafted from premium raw materials and adhere to both national and international standards.

The forging temperature for LDX 2101 Coils ranges from 1100°C to 1250°C, requiring reheating as necessary and air cooling. Lean Duplex Steel 2101 Sheets, Plates, and Coils feature a two-phase ferritic and austenitic structure, containing 22% chromium, 3% molybdenum, and 5-6% nickel alloy.Our ASTM A240 Lean Duplex Steel Sheets offer superior corrosion resistance, with much of the Duplex S31803 currently produced also meeting Duplex S31803 standards. Additionally, we manufacture high-quality Duplex ASTM A240 UNS S32101 Cold Rolled Plates with a mixed microstructure of austenite and ferrite, targeting a 50/50 blend, though commercial alloys may vary between 40/60.

Lean Duplex stainless steels combine high strength with corrosion resistance, outperforming Austenitic grades like 316L. With low nickel and molybdenum content, this grade remains cost-efficient and serves as an excellent alternative to standard austenitic grades such as 304, 304L, and 316L in most environments.
