ATSM A790 Duplex Stainless Steel Pipe S32101 Good general corrosion
resistance
Product Discription:
Duplex stainless steel 2101 (UNS S32101) offers high strength and
corrosion resistance, comparable to certification grades such as
316L. Due to their low nickel and molybdenum content, excellent
mechanical properties and good corrosion resistance, they can be
used in a variety of applications, providing durability and
long-term cost effectiveness.
Characteristics:
- High resistance to chloride stress corrosion cracking
- Chloride pitting and crevice corrosion resistance comparable to
316L stainless
- Good general corrosion resistance
- High strength
- Good sulfide stress corrosion resistance
- Good machinability and weldability
Corrosion Resistance: The corrosion resistance of S32101 is generally good, and therefore is suitable for use in a wide
range of general-purpose applications and environments.
Attributable to its duplex structure, S32101 offers an excellent resistance to stress corrosion cracking. It
also offers corrosion resistance comparable to 304L and 316L
stainless steel, making it an excellent candidate to replace 300
series stainless in a wide variety of applications.
Use of S32101 duplex stainless steel:
Storage Tanks: Palm oil, Wine, Marble slurry, Potable and Sewage
water, Ethanol, Fruit juice, Biodiesel
Infrastructure: Bridges, Sluice gates
General-purpose applications and environments:Heat Exchangers,
Water Heaters, Sea-water systems, Flue-gas cleaning.
