Stainless Steel 310/310S (UNS S31000/UNS S31008)

wilsonpipeline Stainless inventory now includes 310/ 310S Flanges, Pipe Fittings and pipes (Alloy 310 UNS S31000 / Alloy 310S UNS S31008), ideally suited for high-temperature applications such as heat treatment and chemical processing equipment.

Overview

General Properties

Alloy 310 is an austenitic stainless steel that combines excellent high temperature properties with good ductility and weldability. It is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and superior strength in temperatures up to 2100°F. Due to its high chromium and nickel content, it is superior to 304 or 309 stainless in most environments.

Applications:

The higher alloyed stainless steels generally have excellent strength at elevated temperatures along with outstanding resistance to creep deformation and environmental attack. Therefore, Alloy 310 is used widely in industries such as heat treatment and chemical processing. Some examples include:

1. Furnace Parts

2. Oil Burner Parts

3. Heat Exchangers

4. Welding Filler Wire and Electrodes

5. Annealing Covers

6. Combustion Tubes

7. Fire Box Sheets

Resistance

wilsonpipeline Stainless inventory now includes 310/ 310S Flanges, Pipe Fittings and pipes provides superior resistance to corrosion and heat exposure, in even the most demanding environments.

Corrosion Resistance:

1. Provides excellent corrosion resistance

2. High chromium content allows for good aqueous corrosion resistance

3. Excellent resistance at normal temperatures and also has good resistance to oxidizing and carburizing atmospheres

Heat Resistance:

1. Good resistance to oxidation in intermittent service in air at temperatures up to 1040°C and 1150°C in continuous service.

2. Good resistance to thermal fatigue and cyclic heating.

3. Widely used where sulphur dioxide gas is encountered at elevated temperatures.

4. Continuous use in 425-860°C range not recommended due to carbide precipitation, if subsequent aqueous corrosion resistance is needed

5. Generally used at temperatures starting from about 800 or 900°C – above the temperatures at which 304H and 321 are effective.

Processing

Fabrication:

1. Commonly used in the heat treatment and process industries due to high temperature and corrosive environments

2. Often fabricated into complex structures

3. Roller-forms, stamps and draws readily

4. Because 310 work hardens, severe forming operations should be followed by an anneal

Weldability:

1. Austenitic stainless steel is generally considered to be weldable

2. Generally considered to have weldability equivalent to 304 and 304L

3. Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion
