SA240 Type 304 304L Plate

Introduction to SA240 Type 304/304L Plates

SA240 Type 304/304L plates are versatile stainless steel materials widely used across industries like chemical processing, construction, and food production. These austenitic stainless steels, defined by the ASME SA240 standard, offer excellent corrosion resistance, durability, and weldability. Type 304 is known for its strength, while Type 304L, with lower carbon content, excels in welding applications. Gangsteel, a leading manufacturer and exporter of ASME SA240 stainless steel plates, provides high-quality SA240 Type 304/304L plates for global projects. This article explains their properties, applications, and benefits in simple terms, using tables for clarity.

What is SA240 Type 304/304L?

SA240 Type 304 and 304L are austenitic stainless steels with similar compositions but distinct advantages. Type 304 has a maximum carbon content of 0.08%, offering robust strength, while Type 304L, with ≤0.03% carbon, is designed for superior weldability. Both contain 18–20% chromium and 8–12% nickel, ensuring excellent corrosion resistance. The following table summarizes their key compositional differences:

Gangsteel’s SA240 Gr 304 and SA240 Gr 304L plates meet ASTM A240 stainless plate standards, ensuring consistent quality for industrial use.

Key Properties of SA240 Type 304/304L Plates

SA240 Type 304/304L plates are valued for their balanced properties, making them suitable for diverse applications. Here’s a breakdown of their key features:

These properties make SA240 Type 304/304L plates a top choice compared to grades like SA240 Gr 201 or SA240 Gr 316, which Gangsteel also supplies.

Applications of SA240 Type 304/304L Plates

SA240 Type 304/304L plates are used in a variety of industries due to their versatility. Below are key applications, summarized in a table for clarity:

Gangsteel’s ASME SA 312/SA 312M stainless pipes complement these plates for integrated systems.

Why SA240 Type 304L Excels in Welding

Type 304L’s low carbon content (≤0.03%) minimizes carbide precipitation during welding, preventing corrosion at weld sites. This makes SA240 Gr 304L ideal for applications requiring strong, corrosion-resistant welds without post-weld annealing. Type 304, while strong, may require additional treatment for welded structures. Gangsteel’s plates are designed for seamless integration with ASME SA 213/SA 213M stainless pipes in welded systems.

Weight Calculation Using SA240 Type 304/304L Density

Both Type 304 and 304L have a density of approximately 7.93 g/cm³ (7930 kg/m³). To calculate the weight of a plate:

Weight (kg) = Density (kg/m³) × Volume (m³)
Volume (m³) = Length (m) × Width (m) × Thickness (m)

Example Calculation:

• Plate: 2 meters long, 1 meter wide, 5 mm (0.005 meters) thick.
• Volume = 2 × 1 × 0.005 = 0.01 m³.
• Weight = 7930 kg/m³ × 0.01 m³ = 79.3 kg.

This is critical for applications like SA240 Gr 310S or SA240 Gr 347, where precise weight is needed.
