Product Description:
2304 (UNS S32304) and S32101 Duplex Stainless Steel Pipes and Pipe Fittings are advanced duplex stainless steel grades designed for high strength, excellent corrosion resistance, and cost efficiency. These materials are widely used in industries requiring superior performance in demanding environments.
Key Features of Duplex 2304 and S32101 Pipes and Fittings
- High Strength: Offers nearly double the yield strength of standard austenitic stainless steels like 304 and 316.
- Excellent Corrosion Resistance:
- Superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments.
- Good resistance to general corrosion in various acidic and alkaline conditions.
- Cost Efficiency:
- Reduced nickel and molybdenum content make these grades more economical without compromising performance.
- Durability:
- High fatigue strength and toughness, even at cryogenic temperatures.
- Environmental Sustainability:
- Lower alloying content reduces the environmental impact.
