sa 240 gr 304 yield strength

Yield Strength of SA 240 GR 304

The yield strength of SA 240 GR 304, 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): ≥205 MPa (29.7 ksi)

This value ensures SA 240 GR 304 can withstand significant loads without permanent deformation, making it suitable for structural applications like pressure vessels and architectural panels. Cold-working (e.g., rolling) can increase yield strength significantly (up to 600-700 MPa in heavily cold-worked conditions), but it reduces ductility. For detailed specifications, refer to our SS 304 data sheet.

Mechanical Properties Context

The yield strength is part of SA 240 GR 304’s broader mechanical properties (annealed condition):

• Yield Strength Significance: The ≥205 MPa yield strength ensures SA 240 GR 304 can handle moderate loads in applications like plat SS 304 3mm or plate 2 mm SUS 304, while its high elongation (≥40%) supports forming without cracking.

Factors Affecting Yield Strength

• Annealing vs. Cold-Working: Annealed SA 240 GR 304 has a minimum yield strength of 205 MPa, but cold-working (e.g., for thin sheets) can increase it, reducing SA 240 304 non magnetic properties slightly.
• Temperature: Yield strength decreases at high temperatures (e.g., ~150 MPa at 600°C), making sa 240 gr 304h better for elevated temperatures.
• Thickness: Thinner plates (e.g., plat stainless 304) may exhibit slightly higher yield strength in cold-rolled forms due to work hardening.

Comparison with Other Grades

• Vs. SA 240 GR 304L: Lower yield strength (≥170 MPa) due to reduced carbon (≤0.03%), but better weldability. See sa 240 gr 304l.
• 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. SS204: SA 240 GR 304 outperforms SS204 vs SS 304 in yield strength and corrosion resistance due to higher nickel content.
• Vs. SA 240 GR 409: 409 (ferritic) has similar yield strength (~220 MPa) but lower corrosion resistance and formability.

For harsher environments, consider sa 240 gr 317l.

Applications Leveraging SA 240 GR 304 Yield Strength

The ≥205 MPa yield strength supports SA 240 GR 304 in:

• Structural Components: Pressure vessels and frameworks requiring moderate strength.
• Food Processing: Tanks and equipment (e.g., plat stainless 304) needing hygiene and formability.
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Decorative panels with aesthetic and load-bearing capacity.
