UNS ASTM Duplex 2304 Stainless Steel Flat Bars Bright Finish As Customized
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
3. How to order?
Please send us your purchase order by email or fax .or you can ask us to send you a proforma invoice for your order .We need to know the following information for your order.
1) Shipping information,company name, street address, phone number, destination sea port
2) Product information – Quantity, Specification (steel type, thickness, width, surface finish)
3) Delivery time required Sheets / Plates, Stainless Steel Circles.
then prices is ok ,pay the deposit ,after finishing processing ,detection,check everyting is ok,after receiving the balance ,we will arrange shipping or let client arrange shipping .
4. Applications
Duplex 2304 is generally used in the same applications in which Alloys 304 and 316L are used. Some examples of these applications include:
Chloride containing environments
Welded pipe systems within the Pulp and Paper, Chemical and Petrochemical, and Water Treatment industries
Transportations
Heat exchanger tubes
Architecture, building, construction
Pressure vessels
Caustic solutions, organic acids
Food industry
