Product Details
Duplex S32304 Stainless Steel Plate BAOSTEEL TISCO 3.0 - 50.0mm Hot
Rolled SS Plate
GENERAL PROPERTIES
Duplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex
stainless steel whose structure is a balance of ferritic and
austenitic. It has general corrosion resistance similar or better
than Alloys 304L and 316L but with yield strength nearly double
that of austenitic stainless steels. Its duplex microstructure and
low nickel and high chromium contents also allows Duplex 2304 to
demonstrate improved stress corrosion resistant properties compared
to 304 and 316. It is typically suitable for all applications in
the -58oF to 572oF (-50oC to 300oC) temperature range and is
designed to feature high mechanical strength, good weldability,
good corrosion resistance, high resistance to stress corrosion
cracking, good machinability, low thermal expansion, good fatigue
properties, high thermal conductivity, and easy fabrication.
Specifications: UNS S32304
CORROSION RESISTANCE:
- Due to its high chromium content of 23%, the corrosion resistance
properties of Duplex 2304 are practically equivalent to those of
Alloy 316L
- Its duplex microstructure and low nickel and high chromium contents
allows Duplex 2304 to have improved stress corrosion resistance
properties compared to the 304L and 316L standard austenitic
grades.
- More resistant to pitting and crevice corrosion resistance that
Alloy 316L
- Outperforms Alloys 304L and 316L in stress corrosion cracking
resistance in chloride containing aqueous solutions
- Its corrosion rate in boiling nitric acid (65%) is higher than that
of Alloy 316L
- Its high yield strength allows Duplex 2304 to perform well in
abrasion/corrosion applications
STRUCTURE
- Microstructure of Duplex 2304 is very stable compared to molybdenum
containing duplex stainless steels
- Contains approximately equal amounts of ferritic and austenitic in
microstructure after annealing in a temperature about
