sa 240 tp 304 equivalent

What is SA 240 TP 304 Equivalent?

SA 240 TP 304 is an austenitic stainless steel specified under ASME SA 240 and ASTM A240 for chromium and chromium-nickel stainless steel plates, sheets, and strips used in pressure vessels and general applications. Equivalent materials are grades from other international standards (e.g., EN, JIS, GB) with similar chemical composition, mechanical properties, and applications. These equivalents enable global sourcing and compatibility for applications like plat stainless 304, plate 2 mm SUS 304, and SA 240 GR 304 pipe. SA 240 TP 304 is known for its non-magnetic properties and a density of 8.00 g/cm³.

Equivalent Grades for SA 240 TP 304

The following table lists the equivalent materials for SA 240 TP 304 across major international standards, along with their UNS number and key characteristics:

*Sources: ASME SA 240, ASTM A240, EN 10088, JIS G4304, GB/T 20878, as of October 14, 2025.

Notes on Equivalents

• AISI 304 (USA): A historical designation, widely used in North America, identical to SA 240 TP 304.
• EN 1.4301 (Europe): Reflects ~18% Cr and 10% Ni (X5CrNi18-10), closely matching SA 240 TP 304’s properties.
• JIS SUS304 (Japan): Common in Asia, used for plates, pipes, and sheets, with identical composition.
• GB 06Cr19Ni10 (China): Matches SA 240 TP 304’s chemistry, widely used in Chinese industries.
• UNS S30400: A global identifier ensuring consistency across standards.

Gangsteel’s sa 240 gr 304 plates are equivalent to these standards, ensuring global compatibility.

Properties of SA 240 TP 304 Material

SA 240 TP 304 serves as a benchmark for its equivalents, with properties supporting its widespread use.

Chemical Composition

• Chromium: Provides corrosion resistance via a passive oxide layer.
• Nickel: Enhances ductility and non-magnetic properties.
• Carbon: Limited to ≤0.08% for weldability, though SA 240 TP 304L (≤0.03%) is preferred for critical welds. See sa 240 gr 304l.

For detailed specifications, refer to our SS 304 data sheet.

Mechanical Properties (Annealed, 8-75 mm thick)

Physical Properties

• Density: 8.00 g/cm³, ideal for lightweight designs (e.g., a 1m x 1m x 3mm plate weighs ~24 kg).
• Melting Point: ~1400-1450°C, suitable for processing.
• Thermal Conductivity: 16.2 W/m·K, moderate for heat transfer.
• Coefficient of Thermal Expansion: 17.2 × 10⁻⁶/K, stable across temperatures.
• Electrical Resistivity: 0.72 × 10⁻⁶ Ω·m, good for non-conductive applications.

Corrosion Resistance and Weldability

SA 240 TP 304 material offers excellent corrosion resistance in:

• Atmospheric conditions, freshwater, and mild acids (food-grade applications).
• General environments, outperforming SS204 vs SS 304 due to higher nickel content.

It is less resistant to chloride-induced pitting compared to SA 240 TP 316L, which contains molybdenum. Weldability is good using ER308 or ER308L fillers, but SA 240 TP 304L is preferred for critical welds to minimize sensitization risks. For chloride-heavy environments, explore sa 240 gr 316l.

Applications of SA 240 TP 304 and Equivalents

SA 240 TP 304 and its equivalents (AISI 304, 1.4301, SUS304, 06Cr19Ni10) are used in:

• Food Processing: Tanks, conveyors, and equipment (hygienic, non-tarnishing).
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Structural and decorative panels like plat stainless 304 or plate 2 mm SUS 304.
• Automotive: Components requiring corrosion resistance and formability.
• Medical Devices: Non-magnetic instruments leveraging non-magnetic properties.

For harsher corrosive environments, consider sa 240 gr 317l. For high-temperature applications, explore sa 240 gr 321 for titanium-stabilized performance.
