sa 240 304l mechanical properties

Overview of SA 240 304L

SA 240 304L is an austenitic stainless steel with a maximum carbon content of 0.03%, enhancing weldability compared to SA 240 GR 304 (≤0.08% carbon). Its SS 304 non magnetic properties and SA 240 304L density of 8.00 g/cm³ make it ideal for applications like plat stainless 304, SA 240 GR 304 pipe, and welded structures. Gangsteel’s sa 240 gr 304l plates are certified for quality and performance.

Mechanical Properties of SA 240 304L

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

*Source: ASME SA 240 and ASTM A240 standards, as of October 14, 2025. Cold-working may increase tensile strength (e.g., up to 800 MPa) but reduces ductility. For details, see our SS 304 data sheet.

Significance of SA 240 304L Mechanical Properties

• Tensile Strength (≥485 MPa): SA 240 304L provides sufficient strength for structural components like pressure vessels and architectural panels.
• Yield Strength (≥170 MPa): Slightly lower than SA 240 GR 304 (≥205 MPa) due to low carbon, but adequate for applications like plat SS 304 3mm.
• Elongation (≥40%): Ensures excellent formability for deep drawing and bending, ideal for plate 2 mm SUS 304.
• Hardness (≤201 HB): Facilitates machining and forming, unlike harder SA 240 304H material.

The low carbon content of SA 240 304L minimizes sensitization during welding, enhancing its suitability for welded applications. For high-temperature needs, explore our sa 240 gr 304h.

Comparison with Other Grades

• Vs. SA 240 GR 304: SA 240 304L has lower strength (tensile ≥485 MPa vs. ≥515 MPa) but superior weldability. See sa 240 gr 304.
• Vs. SA 240 316L: SA 240 304L shares similar mechanical properties but lacks 316L’s molybdenum for enhanced corrosion resistance. Check sa 240 gr 316l.
• Vs. 200 Series: SA 240 304L outperforms SS204 vs SS 304 in strength and corrosion resistance due to higher nickel content.

For harsher environments, consider our sa 240 gr 317l.

Applications Leveraging SA 240 304L Properties

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

• Food Processing: Welded tanks and equipment requiring hygiene and formability.
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Structural panels and decorative elements like plat stainless 304.
