Product Description

Stainless Steel 310 Pipe is an austenitic stainless steel pipe containing 25% chromium and 20% nickel, offering excellent high-temperature oxidation resistance and strength. It is manufactured through seamless or welded processes to eliminate the risk of carbide precipitation at high temperatures.

310 stainless steel is known for its heat-resistant composition of over 25% chromium (Cr) and 20% nickel (Ni), which provides outstanding oxidation resistance and structural stability during continuous operation at 1100°C.This makes it an ideal choice for high-temperature furnace systems, heat treatment equipment, furnace tubes, and exhaust systems.

JBLSTEEL is one of the best Stainless Steel 310 Pipe manufacturers, suppliers in China, supplying various types of Stainless Steel 310 Pipe in different sizes according to industry needs.

310 Stainless Steel Pipe Feature

Superior High-Temperature Oxidation Resistance

At high temperature environments (>1000°C), silicon elements still form a dense oxide film on the surface, preventing further metal oxidation or spalling; Superior performance compared to 304 stainless steel at 1100°C.

Suitable for high-temperature applications such as gas turbines, incinerators, industrial furnaces, and heat exchange systems.

Excellent Corrosion Resistance

High chromium-nickel content resists sulfidation corrosion, suitable for acidic environments.

Excellent Resistance to Thermal Fatigue and Creep

The high nickel content makes 310 stainless steel maintain its mechanical strength even under frequent thermal cycling, resisting cracking or fracture.

Excellent Weldability and Formability

Compatible with multiple processes, including TIG/MIG, plasma welding, and laser welding, without post-weld heat treatment.

Suitable for cold/hot forming, supporting custom thick-walled or thin-walled structures.

Stabilized Microstructure at High Temperatures

Excellent corrosion resistance in carbon- or sulfur-containing gas environments, significantly superior to 304/316 series stainless steels.

High-temperature Resistance

Continuous operating temperature,maximum: Approximately 1100°C (approximately 2000°F);

Intermittent operating temperature,maximum: Up to 1150°C (approximately 2100°F);

Oxidation/Carburization Resistance: Maintains strength from 800-900°C; forms dense oxide layer to prevent further corrosion;

Thermal Expansion: Approx. 17.5 × 10⁻⁶/K (0-525°C)

310S Stainless Steel

310S (UNS S31008) is a high-alloy austenitic stainless steel, the low-carbon variant of the 310 stainless steel. It retains the high chromium (24–26%) and high nickel (19–22%) content advantages of the 310 grade while reducing carbon content to ≤0.08%, significantly improving weldability, resistance to sensitization, and high-temperature strength.

310 Stainless Steel Pipe Properties

Chemical Composition

The chemical properties of 310 stainless steel pipe provide excellent high-temperature resistance and corrosion resistance, making it an ideal choice for a wide range of applications.

Mechanical Properties

Grade	Density	Melting Point	Tensile Strength	Yield Strength (0.2%Offset)	Elongation
310/310S	7.9 g/cm3	1402 °C (2555 °F)	Psi – 75000 , MPa – 515	Psi – 30000 , MPa – 205	40 %

Material Selection Recommendations

For equipment operating continuously at high temperatures (>800°C) and requiring welding, consider 310S as the preferred choice.

If components primarily operate at moderate to low temperatures (<800°C) and are cost-sensitive, 310 may be considered.

For environments involving strong acids/alkalis or chlorides, more pitting-resistant molybdenum-based stainless steels like 316/317 are preferred.
