Overview of Alloy 2304

UNS S32304, also known as Alloy 2304, is a versatile duplex stainless steel plate that combines the advantages of austenitic and ferritic stainless steels. It is available in thicknesses ranging from 1.0mm to 80.0mm, with custom cutting options to meet specific project requirements.

Chemical Composition (Typical, % by Weight)

The balanced chemistry of UNS S32304 contributes to its excellent mechanical properties and corrosion resistance:
 
  • Chromium (Cr): 21.5 - 23.5
  • Nickel (Ni): 3.0 - 5.0
  • Molybdenum (Mo): 0.05 - 0.6
  • Manganese (Mn): ≤ 2.0
  • Silicon (Si): ≤ 1.0
  • Carbon (C): ≤ 0.03
  • Nitrogen (N): 0.08 - 0.20
  • Phosphorus (P): ≤ 0.03
  • Sulfur (S): ≤ 0.015

Mechanical Properties

Alloy 2304 duplex stainless steel plates exhibit high strength and good ductility, making them suitable for structural and load-bearing applications:
  • Tensile Strength: ≥ 600 MPa
  • Yield Strength (0.2% offset): ≥ 400 MPa
  • Elongation: ≥ 25% (in 50mm gauge length)
  • Hardness: ≤ 290 HV (Brinell hardness: ≤ 280 HB)

Product Standards of UNS S32304 Stainless Steel Plate

UNS S32304 plates are manufactured and tested in accordance with international standards to ensure quality and consistency:
  • ASTM A240 / A240M (Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications)
  • EN 10088-2 (Stainless steels - Part 2: Technical delivery conditions for sheet/plate and strip of corrosion-resistant steels for general purposes)
  • JIS G4305 (Stainless steel plates, sheets and strips)

Equivalent 

UNS S32304 is known by the following designations in different standards:
  • DIN: 1.4362
  • EN: X2CrNiN23-4
  • GB/T: 022Cr23Ni4N

Product Features

  1. Balanced Microstructure: Consists of approximately 50% austenite and 50% ferrite, combining the corrosion resistance of austenitic steels with the high strength of ferritic steels.
  2. Excellent Corrosion Resistance: Resistant to general corrosion, pitting, and crevice corrosion in environments such as freshwater, seawater, and mild chemical solutions. It performs well in chloride-containing environments compared to 304 austenitic stainless steel.
  3. High Strength: Offers twice the yield strength of 304 or 316 austenitic stainless steels, reducing material thickness and weight in structural designs.
  4. Good Weldability: Can be welded using common methods (e.g., TIG, MIG) with minimal risk of sensitization, thanks to its low carbon content.
  5. Cost-Effective: Contains lower nickel content than 316 stainless steel, providing a more economical alternative without compromising performance in many applications.

Applications

Due to its balanced properties, UNS S32304 duplex stainless steel plates are widely used in:
  • Oil and Gas Industry: Pipelines, storage tanks, and offshore platforms (resistant to seawater and hydrocarbon environments).
  • Chemical Processing: Reactors, tanks, and piping for handling mild acids and corrosive fluids.
  • Water Treatment: Desalination plants, water pipelines, and wastewater equipment (resistant to chloride-induced corrosion).
  • Construction: Structural components, architectural cladding, and bridges (high strength reduces material usage).
  • Food and Beverage Industry: Equipment for processing and storage, where hygiene and corrosion resistance are critical.
