Product Parameter

Key Features

1. Low Carbon Content

310S contains a maximum of 0.08% carbon, lower than standard 310 stainless steel. This low-carbon composition helps reduce chromium carbide precipitation during welding and thermal exposure, improving resistance to intergranular corrosion in fabricated components.

2. High-Temperature Oxidation Resistance

With approximately 25% chromium and 20% nickel, 310S forms a protective chromium oxide layer that supports oxidation resistance at elevated temperatures. It is suitable for furnace atmospheres, combustion gases, and other high-temperature oxidizing environments.

3. Seamless Pipe Construction

The hot-rolled seamless process produces pipe without a longitudinal welded seam. This continuous tubular structure is suitable for industrial applications where seamless construction is required.

4. Multiple Fabrication Options

JILAIDA supports cut-to-length, beveled ends, pickling, passivation, and other specified finishing requirements. These options allow the pipe to be prepared for different fabrication and installation conditions.

5. Suitable for Demanding Thermal Service

The combination of high chromium and nickel content with the lower carbon composition makes 310S suitable for selected components exposed to elevated temperatures, thermal cycling, and oxidizing atmospheres.

High-Temperature Performance

310S Stainless Steel Seamless Pipe is mainly selected for applications where elevated temperature and oxidation resistance are important material requirements. Its chromium and nickel content supports performance in high-temperature oxidizing environments, while the lower carbon level improves its suitability for welded and thermally processed components.

Actual material selection should consider service temperature, atmosphere, mechanical loading, thermal cycling, welding conditions, and the requirements of the complete equipment system.

Product Application

Heat Treatment Equipment

310S seamless pipe can be used for radiant tubes, furnace rollers, retorts, and other tubular components exposed to high-temperature furnace environments.

Boiler and Heat Recovery Systems

The material is suitable for selected superheater and reheater tube applications where elevated-temperature service requires heat-resistant stainless steel.

Petrochemical Equipment

310S can be used in selected high-temperature petrochemical equipment, including components associated with ethylene pyrolysis and furnace systems.

Industrial Incineration

The pipe can be used for burner nozzles, flame tubes, and other tubular components exposed to combustion gases and elevated operating temperatures.

Temperature Measurement Systems

310S seamless pipe can be used as thermocouple protection sheaths in high-temperature environments such as molten metal and glass processing.

Automotive and Marine Systems

Selected exhaust-related tubular components can use 310S where elevated-temperature oxidation resistance is required.

Kiln and Furnace Components

The material is also suitable for selected tubular and structural components used in ceramic kilns, heat-treatment baskets, and related high-temperature equipment.

Material Comparison

310S is generally considered when an application requires stronger high-temperature performance than common austenitic stainless steel grades while also benefiting from the lower carbon content of the 310S grade.

The final material should be selected according to service temperature, process atmosphere, mechanical requirements, welding conditions, and the applicable specification.

Manufacturing Process

JILAIDA manufactures 310S seamless pipe through a hot-rolled seamless process, followed by dimensional and surface processing according to the required specification.

Hot-Rolled Seamless Production

The seamless process forms the tubular product without a longitudinal welded seam, creating a continuous pipe structure for industrial applications.

Straightening

Straightening is applied to improve dimensional consistency after the hot-rolling stage.

Pickling and Passivation

Pickling and passivation can be used to remove surface oxides and provide a cleaner stainless steel surface for subsequent fabrication and use.

Finishing and Cutting

According to project requirements, the pipe can be cut to specified lengths and supplied with beveled ends or other agreed surface finishes.

Quality and Documentation

For industrial procurement, material traceability and inspection documentation are important when 310S pipe is used in boilers, heat-treatment equipment, petrochemical systems, and other demanding applications.

Available documentation may include:

1. EN 10204 3.1 Material Test Certificate
2. Chemical composition records
3. Mechanical test results
4. Certificate of Origin
5. Commercial Invoice and Packing List

Hydrostatic or eddy current testing can be arranged according to the applicable product specification and order requirements. Third-party inspection can also be coordinated when required.

Frequently Asked Questions

Q1: What is the difference between 310S and standard 310 stainless steel?

A: The main difference is carbon content. 310S has a maximum carbon content of 0.08%, which is lower than standard 310. The lower carbon level helps reduce sensitization and intergranular corrosion risk after welding or prolonged thermal exposure.

Q2: What sizes are available?

A: The standard range covers outer diameters from 6mm to 89mm, wall thicknesses from 3mm to 30mm, and lengths from 3000mm to 10000mm. Customized dimensions can be discussed according to project requirements.

Q3: Is the pipe seamless?

A: Yes. The pipe is manufactured through a hot-rolled seamless process without a longitudinal welded seam.

Q4: Can the pipe be cut to a specified length?

A: Yes. JILAIDA supports cut-to-length requirements. Please provide the required finished length and quantity when requesting a quotation.

Q5: Can beveled ends be supplied?

A: Yes. Beveled ends can be provided according to fabrication or installation requirements. The required end configuration should be confirmed before production.

Q6: Is 310S suitable for high-temperature applications?

A: Yes. 310S is a heat-resistant austenitic stainless steel with high chromium and nickel content, making it suitable for many elevated-temperature and oxidizing environments. Final material selection should consider the actual temperature, atmosphere, mechanical requirements, and service conditions.

Q7: What surface treatments are available?

A: Depending on order requirements, the pipe can undergo straightening, pickling, passivation, and specified surface finishing. The required surface condition should be confirmed before production.
