Overview of SA 240 GR 304L Material

SA 240 GR 304L material is an austenitic stainless steel specified under ASME SA 240 and ASTM A240 for plates, sheets, and strips used in pressure vessels and general corrosive service.

As a low-carbon variant of SA 240 GR 304, it contains ≤0.03% carbon, enhancing weldability by reducing sensitization risks (chromium carbide precipitation). With a density of 8.00 g/cm³ and non-magnetic properties in the annealed state, SA 240 GR 304L material is ideal for welded applications like plat SS 304 3mm, plate 2 mm SUS 304, and chemical tanks. Gangsteel’s sa 240 gr 304l plates ensure compliance and quality.

Chemical Composition of SA 240 GR 304L Material

The chemical composition of SA 240 GR 304L material ensures excellent corrosion resistance and weldability:

• Chromium: Forms a passive oxide layer for corrosion resistance.
• Nickel: Enhances ductility and non-magnetic properties.
• Carbon: Low (≤0.03%) minimizes sensitization, making SA 240 GR 304L material ideal for welding compared to SA 240 GR 304 (≤0.08% carbon).

For detailed specifications, refer to our SS 304 data sheet.

Mechanical Properties of SA 240 GR 304L Material

The mechanical properties of SA 240 GR 304L material for annealed plates (8-75 mm thick) support its use in structural and forming applications:

• Comparison: Slightly lower strength than SA 240 GR 304 (tensile ≥515 MPa, yield ≥205 MPa) due to reduced carbon, but superior weldability. Cold-working can increase tensile strength (up to 800 MPa) but reduces ductility.

Physical Properties

• Density: 8.00 g/cm³, ideal for lightweight designs (e.g., a 1m x 1m x 3mm plate weighs ~24 kg).
• Melting Point: ~1400-1450°C, suitable for processing.
• Thermal Conductivity: 16.2 W/m·K, moderate for heat transfer.
• Coefficient of Thermal Expansion: 17.2 × 10⁻⁶/K, stable across temperatures.
• Electrical Resistivity: 0.72 × 10⁻⁶ Ω·m, good for non-conductive applications.

These properties make SA 240 GR 304L material suitable for plat stainless 304 and plate 2 mm SUS 304.

Corrosion Resistance and Weldability

SA 240 GR 304L material offers excellent corrosion resistance in:

• Atmospheric conditions, freshwater, and mild acids (food-grade applications).
• General environments, outperforming SS204 vs SS 304 due to higher nickel content.

It is less resistant to chloride-induced pitting compared to SA 240 GR 316L, which contains molybdenum. Weldability is superior with ER308L fillers, as the low carbon content minimizes sensitization, making it ideal for welded applications like SA 240 GR 304 pipe. For chloride-heavy environments, explore sa 240 gr 316l.

Applications of SA 240 GR 304L Material

SA 240 GR 304L material is used in:

• Food Processing: Welded tanks, conveyors, and equipment (hygienic, non-tarnishing).
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Structural and decorative panels like plat stainless 304.
• Medical Devices: Non-magnetic components leveraging non-magnetic properties.
• Pharmaceuticals: Equipment requiring cleanability and corrosion resistance.

For harsher environments, consider sa 240 gr 317l or sa 240 gr 321 for high-temperature stability.
