310/310S Stainless Steel Pipe–High Temperature Furnace Tubing Manufacturer | Womic Steel

310 and 310S stainless steel pipes are high-temperature resistant austenitic stainless steel materials widely used in extreme heat environments. Compared with conventional austenitic stainless steels such as 304 or 316, Grade 310 stainless steel pipe contains significantly higher chromium and nickel content, which provides exceptional oxidation resistance, superior creep strength, and stable mechanical properties at elevated temperatures.

310 stainless steel pipe typically contains approximately 25% chromium and 20% nickel, forming a highly stable austenitic structure capable of maintaining strength and corrosion resistance in continuous service conditions approaching 1000–1100°C. Because of these characteristics, 310 stainless steel pipes are frequently used in industrial furnace systems, heat treatment plants, petrochemical processing units, thermal power stations, and high-temperature process pipelines.

The low carbon version, 310S stainless steel pipe, is designed to reduce carbide precipitation during welding and high-temperature exposure. This improves weldability and minimizes the risk of intergranular corrosion, making 310S stainless steel pipe particularly suitable for welded piping systems and furnace components that operate under repeated heating cycles.

Due to its excellent resistance to oxidation scaling and high-temperature corrosion, 310 / 310S stainless steel pipe has become one of the most widely used heat-resistant stainless steel grades in industries such as metallurgy, petrochemical refining, power generation, and chemical processing. As a professional stainless steel pipe manufacturer, Womic Steel supplies high-quality 310 and 310S stainless steel pipes for demanding industrial applications worldwide.

310 and 310S stainless steel pipes are produced according to internationally recognized standards that define dimensional tolerances, chemical composition limits, mechanical performance, and inspection requirements.

Typical manufacturing standards include:

ASTM / ASME Standards

ASTM A312 – Seamless and welded austenitic stainless steel pipes for high-temperature service
ASTM A213 – Stainless steel boiler and heat exchanger tubes
ASTM A269 – General service stainless steel tubing
ASTM A358 – Electric fusion welded stainless steel pipes
ASTM A376 – Stainless steel pipe for high-temperature central station service

ASME Standards

ASME SA312
ASME SA213

European Standards

EN 10216-5 – Seamless stainless steel pipes for pressure purposes
EN 10217-7 – Welded stainless steel pipes

Japanese Standards

JIS G3459 – Stainless steel pipes for piping

These standards ensure that 310 stainless steel pipes are manufactured with consistent chemical composition, dimensional accuracy, and mechanical reliability suitable for industrial engineering applications.

The excellent high-temperature performance of 310 stainless steel pipe is mainly derived from its unique alloy composition. The combination of high chromium and nickel provides superior oxidation resistance and structural stability during long-term exposure to elevated temperatures.

Typical chemical composition is shown below:

The high chromium content promotes the formation of a protective chromium oxide film, which significantly enhances oxidation resistance at high temperatures. Nickel stabilizes the austenitic microstructure and improves creep resistance and thermal fatigue resistance under cyclic heating conditions.

310 / 310S stainless steel pipes provide stable mechanical properties even under high-temperature operating conditions.

Typical mechanical properties include:

These properties ensure reliable performance in pressure piping systems, furnace tubes, and heat exchanger applications where both mechanical strength and ductility are required.

One of the most important advantages of 310 stainless steel pipe is its exceptional resistance to oxidation scaling at high temperatures.

The alloy can withstand continuous operating temperatures up to approximately 1100°C in oxidizing environments. This makes 310 stainless steel pipe one of the preferred materials for industrial furnace components, radiant heater tubes, and thermal processing equipment.

In high-temperature atmospheres containing oxygen, chromium in the alloy reacts to form a stable chromium oxide layer on the pipe surface. This protective layer prevents further oxidation and significantly extends the service life of the piping system.

Compared with conventional stainless steels such as 304 or 316, 310 stainless steel pipe offers much higher resistance to scaling and thermal degradation, making it highly suitable for continuous high-temperature industrial processes.

The manufacturing process of stainless steel pipes plays a critical role in determining their structural integrity and dimensional accuracy.

Seamless Pipe Production

The seamless pipe manufacturing process generally includes the following stages:

1 Billet selection and inspection
2 Billet heating in rotary furnace
3 Rotary piercing to produce hollow shell
4 Hot rolling or extrusion to achieve desired diameter
5 Cold drawing or cold rolling for dimensional precision
6 Solution annealing heat treatment
7 Acid pickling and surface cleaning
8 Straightening and final inspection

Welded Pipe Production

Welded 310 stainless steel pipes are typically produced from stainless steel plates or coils using advanced welding technologies such as:

TIG welding
Laser welding
Automatic submerged arc welding

After welding, pipes undergo heat treatment and non-destructive testing to ensure weld integrity and mechanical performance.

Solution annealing is an essential heat treatment process for 310 stainless steel pipes. The purpose of solution annealing is to dissolve chromium carbides, restore the austenitic structure, and improve corrosion resistance.

Typical heat treatment parameters include:

Solution Annealing Temperature: 1040 – 1150°C
Cooling Method: Rapid water quenching or air cooling

This heat treatment process ensures optimal microstructure stability and prevents carbide precipitation that may affect corrosion resistance.

Depending on application requirements, 310 stainless steel pipes can be supplied with different surface finishes.

Common finishes include:

Pickled industrial surface

Matte mill finish

Bright annealed (BA) surface

Polished surface finish

Pickled surfaces are commonly used in industrial furnace and petrochemical applications, while polished surfaces may be used in decorative or specialized processing equipment.

To guarantee the reliability and safety of stainless steel pipes in demanding industrial environments, strict inspection and testing procedures are implemented during production.

Typical inspection procedures include:

Chemical composition analysis

Mechanical property testing

Hydrostatic pressure testing

Ultrasonic testing (UT)

Eddy current testing (ET)

Positive material identification (PMI)

Dimensional inspection

Visual surface examination

These comprehensive tests ensure that each pipe complies with applicable international standards and meets the performance requirements of industrial projects.

Due to its excellent high-temperature resistance, 310 stainless steel pipe is widely used in various industrial sectors.

Typical applications include:

Industrial furnace tubing

Heat treatment equipment

Radiant heater tubes

Petrochemical processing units

Thermal power plant pipelines

Boiler superheater tubes
