Unimix Metal Cooperation manufactures, exports, and supplies Lean Duplex 2101 pipes in compliance with international ASTM standards. Our UNS S32101 Duplex Steel Pipes are stronger and harder than regular steel, though they are not as corrosion-resistant as stainless steel.
UNS S32101 Bush Hex Pipes are austenitic-ferritic stainless steel designed for corrosive environments, offering resistance to localized corrosion such as pitting, crevice corrosion, and stress corrosion cracking. Their unique chemical composition ensures mechanical strength, enabling them to withstand high-stress conditions where ordinary austenitic stainless steel would fail.
We supply Lean Duplex ASTM A815 UNS S32101 Bush Hex Tubes to industries ranging from basic sectors like Sugar, Paper, Textile, and Engineering to advanced fields such as Oil & Gas, Petrochemical, Chemical & Fertilizers, Power Generation, and Nuclear Industries.
Lean Duplex stainless steels combine high strength with corrosion resistance, outperforming austenitic grades like 316L. With low nickel and molybdenum content, this grade offers cost stability and can replace standard austenitic grades like 304, 304L, and even 316L in most settings.
Key Properties:
High chromium, molybdenum, and nitrogen levels provide superior corrosion resistance compared to 316 and 316L.
Excellent resistance to pitting and crevice corrosion in oxidizing and acidic solutions.
Resistant to chloride stress corrosion cracking at temperatures up to 302°F (150°C).
The ferrite content ensures good performance in caustic environments.
Like other duplex stainless steels, Duplex 2205 offers strong oxidation resistance.
