Product Specification

Plate A240 UNS S32304 DUPLEX 2304 DIMENSION 2*1 METER THICKNESS 5MM

Stainless steel sheet/plate

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

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

STANDARDS:

• ASTM/ASME: UNS S32304
• EURONORM: FeMi35Cr20Cu4Mo2

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

Due to the many great features of stainless steel, it is widely used in many industries. It includes constructions, home appliances, automobiles, kitchen accessories, mechanical structure, decoration engineering, chemical industry, etc. Let's have a brief review.

1. Construction & Buildings
It is an essential building material widely used in commercial buildings, bridges, airports, etc. The most common uses include structural frames, roofing, wall panels, claddings, door panels, backsplash, handrailings, ceilings, elevator hall, inner panels of elevators, etc. Also, it is perfect for making handicrafts.

2. Automobile
Different grades of stainless steel can be used to manufacture car bodies, grills, trims, wheel axles, bearings, vehicular exhaust, fuel tanks, etc.

3. Industrial Uses
Stainless steel is ideal for transporting chemicals, liquids, etc. It is typical for medical uses, gas and oil industries, such as pipelines and tubes, blades, operation tables, pumps, processing or storage tanks & vessels, etc.

4. Household Appliances
About 75% of household appliances are made of stainless steel, including internal panels of cookers, heaters, ovens, burners, conveyors, grills, television, washing machine, refrigerator, kitchen hardware, etc.

5. Furniture & Daily Uses
Stainless steel coil and sheet are also versatile in our daily life, such as trash cans, screens, benches, tables, beds, bookshelves, advertising boards, display stands, etc.
