sa 240 gr 304l chemical composition

What is SA 240 GR 304L?

SA 240 GR 304L, a low-carbon variant of SA 240 GR 304, is an austenitic stainless steel specified under ASME SA 240. Its chemical composition ensures excellent corrosion resistance and superior weldability, making it ideal for pressure vessels and structural components. The “L” denotes low carbon, reducing the risk of sensitization during welding. At Gangsteel, our sa 240 gr 304l plates are crafted to meet global standards.

Chemical Composition of SA 240 GR 304L

The chemical makeup of SA 240 GR 304L is tightly controlled to ensure performance. Below is the typical composition (by weight percentage) as per ASME SA 240:

• Carbon (C): 0.00 - 0.03% (low carbon minimizes carbide precipitation)
• Manganese (Mn): 0.00 - 2.00%
• Silicon (Si): 0.00 - 0.75%
• Phosphorus (P): 0.00 - 0.045%
• Sulfur (S): 0.00 - 0.03%
• Chromium (Cr): 17.50 - 19.50% (enhances corrosion resistance)
• Nickel (Ni): 8.00 - 12.00% (improves ductility and toughness)
• Nitrogen (N): 0.00 - 0.10%
• Iron (Fe): Balance

This composition ensures SA 240 GR 304L remains SS 304 non magnetic in its annealed state. For detailed specs, download our SS 304 data sheet.

Why Low Carbon Matters in SA 240 GR 304L

The low carbon content (≤0.03%) in SA 240 GR 304L prevents chromium carbide formation during welding, reducing intergranular corrosion risks. Compared to SA 240 GR 304, which has up to 0.08% carbon, 304L is better suited for welded applications. This makes it a preferred choice over SA 240 GR 304H material for environments requiring high corrosion resistance. Gangsteel’s sa 240 gr 304 and 304L plates are dual-certified for flexibility.

Physical and Mechanical Properties

The SA 240 GR 304L density is 8.00 g/cm³, identical to SS 304 plate density, ensuring lightweight yet durable performance. Its mechanical properties include a tensile strength of 485-515 MPa and yield strength of ≥170 MPa, with excellent elongation (>40%) for formability. These properties make SA 240 GR 304L ideal for plat stainless 304 applications, from 2 mm SUS 304 to thicker plates. Explore our sa 240 gr 316l for enhanced corrosion resistance.

Applications of SA 240 GR 304L

Thanks to its balanced chemical composition, SA 240 GR 304L is used in food processing, chemical tanks, and architectural panels. Its SS 304 non magnetic nature suits electronic and medical equipment. Compared to SS204 vs SS 304, 304L offers superior corrosion resistance at a competitive SS 304 plate price. Gangsteel provides plat SS 304 3mm and other sizes at market-leading rates. Contact admin@gangsteel.com for a quote.

Comparing SA 240 GR 304L with Other Grades

Versus SA 240 GR 304, 304L excels in weldability but has slightly lower strength. Compared to SA 240 GR 316, it’s more cost-effective but less resistant to chloride pitting. For high-temperature needs, SA 240 GR 304H material is better suited. Gangsteel’s sa 240 gr 304h and sa 240 gr 317l complement our 304L offerings.
