Product Description

SS 310 pipe is an austenitic stainless steel grade specifically designed for high-temperature applications. With excellent oxidation resistance and good strength at elevated temperatures, this grade is the preferred choice for furnace parts, heat treatment equipment, and high-temperature industrial piping systems.

The 310 grade contains high levels of chromium (24-26%) and nickel (19-22%), which provide exceptional resistance to scaling at temperatures up to 1100°C (2012°F) under intermittent service and 1150°C (2100°F) under continuous service. This makes SS 310 pipe far superior to standard 304 or 316 grades when heat resistance is the primary requirement.

UNS S31000 is the standard designation for this grade, and ASTM A312 is the governing specification for seamless and welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. Both seamless and welded constructions are available, depending on your application requirements.

Beyond high-temperature performance, SS 310 pipe also offers good resistance to sulfidation and carburization, making it suitable for reducing or oxidizing atmospheres. However, it is important to note that 310 has lower corrosion resistance when exposed to aqueous solutions compared to 316L, so its primary application focus remains thermal.

Key advantages of SS 310 pipe:

  • Outstanding oxidation resistance up to 1100°C (2012°F)
  • High creep strength for sustained high-temperature loading
  • Resistance to carburization and sulfidation in aggressive furnace atmospheres
  • Good ductility and weldability for fabrication
  • Suitable for both continuous and intermittent high-temperature service

Chemical Composition (ASTM A312 TP310 UNS S31000)

The chemical composition of SS 310 pipe is strictly controlled to ensure high-temperature performance and oxidation resistance.

Element Content (% by weight)
Carbon (C) 0.25 max
Manganese (Mn) 2.00 max
Silicon (Si) 1.50 max
Phosphorus (P) 0.045 max

Manufacturing & Finishing
Manufacturing Processes

Seamless Pipe
Produced by hot extruding or cold drawing solid billets to form a hollow tube. Seamless construction provides uniform strength with no weld seam, making it ideal for high-pressure and high-temperature applications.

Welded Pipe (ERW / EFW)
Formed from flat rolled coils, then welded longitudinally. Electric Fusion Welding (EFW) is used for larger diameters. Welded pipes are available with or without post-weld heat treatment.

Surface Finishing
Finish Description
Pickled (AP) Acid pickled to remove mill scale and heat tint
Bright Annealed (BA) Annealed in controlled atmosphere for a bright, oxide-free surface
Polished Mechanical polishing to various grit finishes (180#, 240#, 400#, etc.)
As-Descaled (AD) Rough surface with scale removed but not polished
Applications

SS 310 pipe is specified for high-temperature applications across multiple industries where oxidation resistance and hot strength are critical.

Heat Treatment and Furnace Equipment
  • Furnace rolls and radiant tubes
  • Retorts, muffles, and burner nozzles
