sa 240 304 mechanical 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.

Mechanical Properties of SA 240 GR 304

The mechanical properties of SA 240 GR 304, for annealed plates (8-75 mm thick), are specified by ASME SA 240 and support its use in structural and forming applications. Below is a table of typical values:

*Source: ASME SA 240 and ASTM A240 standards, as of October 14, 2025. Cold-working can increase tensile strength (e.g., up to 900 MPa) but reduces ductility. For detailed specifications, refer to our SS 304 data sheet.

Significance of Mechanical Properties

• Tensile Strength (≥515 MPa): Ensures SA 240 GR 304 can withstand significant loads, making it suitable for pressure vessels, structural frameworks, and architectural components.
• Yield Strength (≥205 MPa): Provides adequate resistance to deformation, ideal for applications like plat SS 304 3mm or plate 2 mm SUS 304.
• Elongation (≥40%): Offers excellent ductility, enabling deep drawing and bending for complex shapes in food processing equipment or decorative panels.
• Hardness (≤201 HB): Facilitates machining and forming, unlike harder alloys like SA 240 GR 304H material, which is designed for high-temperature strength.

These properties make SA 240 GR 304 versatile, though its higher carbon content (≤0.08%) requires careful welding to avoid sensitization compared to SA 240 GR 304L. For welding-focused applications, explore our sa 240 gr 304l.

Comparison with Other Grades

• Vs. SA 240 GR 304L: 304L has lower strength (tensile ≥485 MPa, yield ≥170 MPa) due to reduced carbon (≤0.03%), but offers better weldability for applications like SA 240 GR 304 pipe.
• Vs. SA 240 GR 316L: Similar strength, but 316L’s molybdenum content enhances corrosion resistance in chloride environments, at a higher SS 304 steel price. See sa 240 gr 316l.
• Vs. 200 Series: SA 240 GR 304 outperforms SS204 vs SS 304 in strength, corrosion resistance, and formability due to higher nickel content.
• Vs. SA 240 GR 409: 304 has better corrosion resistance and formability than ferritic 409, which is cheaper but prone to surface rust. For high-temperature applications, consider sa 240 gr 304h.

For harsher corrosive environments, explore our sa 240 gr 317l or sa 240 gr 321 for enhanced performance.

Applications Leveraging SA 240 GR 304 Mechanical Properties

The mechanical properties of SA 240 GR 304 make it ideal for:

• Food Processing: Tanks, conveyors, and equipment requiring strength, formability, and hygiene.
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Structural and decorative panels like plat stainless 304, leveraging its ductility and aesthetic finish.
• Automotive: Components requiring moderate strength and corrosion resistance.
