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:
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.

Gangsteel offers competitive SS 304 plate price options for these applications, ensuring cost-effective solutions.
As of October 14, 2025, SA 240 GR 304L plate prices (2B finish, 3-6mm thick) range from $1.50-$3.45/kg globally, influenced by nickel prices (~$15,325/t). Gangsteel offers competitive pricing at $1.50/kg FOB (MOQ 1 ton) for sa 240 gr 304l plates, including custom sizes like plat SS 304 3mm, with finishes like 2B, No.1, and polished. Prices are 0-5% lower than SA 240 GR 304 ($1.55-$3.50/kg) due to higher welding demand.
Gangsteel provides certified SA 240 GR 304L plates with reliable yield strength and competitive SS 304 plate price. Our inventory includes SA 240 TP 304/304L dual-certified plates for versatility and supports global delivery for applications from plat stainless 304 to heavy plates.
