What is sa 240 304l yield strength?

Yield Strength of SA 240 GR 304L

The yield strength of SA 240 GR 304L, as specified by ASME SA 240 for annealed plates (8-75 mm thick), is the stress at which the material begins to deform plastically (0.2% offset). The minimum yield strength is:

• Yield Strength (0.2% Offset): ≥170 MPa (24.7 ksi)

This value ensures SA 240 GR 304L can withstand moderate loads without permanent deformation, making it suitable for applications like pressure vessels, food processing equipment, and plat SS 304 3mm. Cold-working (e.g., rolling) can increase yield strength significantly (up to 500-600 MPa in heavily cold-worked conditions), but it reduces ductility and may slightly affect SA 240 304 non magnetic properties. For detailed specifications, refer to our SS 304 data sheet.

Mechanical Properties Context

• Yield Strength Significance: The ≥170 MPa yield strength, slightly lower than SA 240 GR 304 (≥205 MPa) due to reduced carbon content, ensures SA 240 GR 304L is suitable for welded applications like plat stainless 304 or plate 2 mm SUS 304, with excellent formability due to high elongation (≥40%).

Factors Affecting Yield Strength

• Annealing vs. Cold-Working: Annealed SA 240 GR 304L has a minimum yield strength of 170 MPa. Cold-working (e.g., for thin sheets) increases yield strength but reduces ductility.
• Temperature: Yield strength decreases at high temperatures (e.g., ~120 MPa at 600°C), making sa 240 gr 304h better for elevated temperatures.
• Thickness: Thinner plates (e.g., plat SS 304 3mm) in cold-rolled forms may exhibit higher yield strength due to work hardening compared to thicker plates.

Comparison with Other Grades

• Vs. SA 240 GR 304: Higher yield strength (≥205 MPa) due to higher carbon (≤0.08%), but less weldable. See sa 240 gr 304.
• Vs. SA 240 GR 316L: Similar yield strength (≥170 MPa), but 316L’s molybdenum enhances corrosion resistance, at a higher SS 304 steel price. Explore sa 240 gr 316l.
• Vs. SS 201: SA 240 GR 304L has lower yield strength (201: ≥260 MPa) but better corrosion resistance and weldability due to higher nickel content (SS204 vs SS 304 is a misnomer; SS 201 is the correct comparison). See sa 240 gr 201.
• Vs. SA 240 GR 409: 409 (ferritic) has similar yield strength (~220 MPa) but poorer corrosion resistance and formability.

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

Applications Leveraging SA 240 GR 304L Yield Strength

The ≥170 MPa yield strength supports SA 240 GR 304L in:

• Food Processing: Welded tanks and equipment (e.g., plat stainless 304) requiring hygiene and formability.
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Decorative panels and structural components like plate 2 mm SUS 304 with moderate load-bearing capacity.
• Medical Devices: Non-magnetic components leveraging SA 240 304 non magnetic properties.
