UNS ASTM Duplex 2304 Stainless Steel Pipe Welded Bright Finish
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.

2. Processing
Weldability
Can be successfully welded by TIG manual and automatic, PLASMA,
MIG, SMAW, SAW, FCAW
Duplex microstructure renders the alloy less sensitive to hot
cracking
Pre-heating and post welding is not required
Filler metal should be a balanced ferrite/austenitic type
Machinability
Exhibits improved machinability properties particularly when
considering drilling
Low speeds and high feeds will minimize this alloys tendency to
work harden
