sa 240 gr 304 material properties

Overview of SA 240 GR 304

SA 240 GR 304 is an austenitic stainless steel specified under ASME SA 240 for plates, sheets, and strips used in pressure vessels and general applications. With a SA 240 GR 304 density of 8.00 g/cm³ and SS 304 non magnetic properties in the annealed state, it’s ideal for applications like plat stainless 304, SA 240 GR 304 pipe, and architectural panels. Gangsteel’s sa 240 gr 304 plates ensure consistent quality and compliance.

Chemical Composition

The chemical composition of SA 240 GR 304 ensures its corrosion resistance and formability:

• Chromium (Cr): Provides corrosion resistance via a passive oxide layer.
• Nickel (Ni): Enhances ductility and toughness.
• Carbon (C): Limited to ≤0.08% for weldability, though SA 240 GR 304L (≤0.03%) is better for welding. See our sa 240 gr 304l.

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

Mechanical Properties

The mechanical properties of SA 240 GR 304, for annealed plates (8-75 mm thick), support its structural and forming capabilities:

These properties make SA 240 GR 304 suitable for plat SS 304 3mm and plate 2 mm SUS 304. Cold-working can increase strength but may reduce ductility. For high-temperature applications, explore sa 240 gr 304h.

Physical Properties

SA 240 GR 304’s physical properties enhance its versatility:

• Density: 8.00 g/cm³, ideal for lightweight designs.
• Melting Point: ~1450°C, suitable for high-temperature processing.
• Thermal Conductivity: 16.2 W/m·K, moderate for heat transfer.
• Coeffic
• ient of Thermal Expansion: 17.2 × 10⁻⁶/K, stable across temperatures.
• Electrical Resistivity: 0.72 × 10⁻⁶ Ω·m, good for non-conductive applications.

Its SS 304 non magnetic nature suits electronic and medical uses. For enhanced corrosion resistance, consider sa 240 gr 316l.

Corrosion Resistance

SA 240 GR 304 offers excellent resistance to:

• Atmospheric corrosion and mild acids (e.g., food acids).
• Freshwater and general environments, outperforming SS204 vs SS 304.

However, it’s less resistant to chloride-induced pitting compared to SA 240 GR 316. For welded applications, SA 240 GR 304L reduces sensitization risks. Gangsteel’s sa 240 gr 317l is ideal for harsher conditions.

Weldability and Fabrication

• Weldability: Good with ER308 filler, though SA 240 GR 304L is preferred for critical welds. Use low heat input to avoid sensitization.
• Formability: High elongation (≥40%) supports deep drawing for plat stainless 304.
• Machinability: Low hardness ensures ease of machining, unlike SA 240 GR 304H material.

Applications

SA 240 GR 304’s properties make it ideal for:

• Food Processing: Tanks and equipment (hygienic, non-tarnishing).
• Chemical Industry: Vessels and SA 240 GR 304 pipe.
• Architecture: Structural and decorative panels (e.g., plate 2 mm SUS 304).
