GENERAL PROPERTIES

• 310S alloy is an austenitic stainless steel bar renowned for its remarkable high temperature resistance, combined with impressive ductility and weldability. Owing to its elevated chromium and nickel content, this alloy excels in high-temperature applications, delivering robust corrosion resistance, outstanding oxidation resistance, and unparalleled strength at temperatures soaring up to 2100°F. Its superior composition allows 310S to surpass 304 or 309 stainless steel bars in most scenarios.

APPLICATIONS

• Higher alloyed stainless steels exhibit remarkable strength at elevated temperatures and exceptional resistance to creep deformation and environmental damage. Consequently, Alloy 310 is extensively utilized in heat treatment and chemical processing industries. Noteworthy applications include:
• Furnace Parts
• Oil Burner Parts
• Heat Exchangers
• Welding Filler Wire and Electrodes
• Annealing Covers
• Combustion Tubes
• Fire Box Sheets

RESISTANCE

Stainless Steel Alloy 310 offers unparalleled resistance to both corrosion and heat, thriving in the most demanding environments.

CORROSION RESISTANCE

• Provides stellar corrosion resistance.
• High chromium content ensures excellent aqueous corrosion resistance.
• Exceptional resistance at standard temperatures, along with impressive performance in oxidizing and carburizing atmospheres.

HEAT RESISTANCE

• Displays strong resistance to oxidation during intermittent service in air at temperatures up to 1040°C and continuous service up to 1150°C.
• Excellent resistance to thermal fatigue and cyclic heating.
• Ideal for environments with *** dioxide gas at elevated temperatures.
• Continuous use in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is needed, due to carbide precipitation.
• Primarily utilized at temperatures starting from around 800 or 900°C, which are above the effective range of 304H and 321.

FABRICATION

• Ideal for use in heat treatment and process industries due to its resilience in high-temperature and corrosive environments.
• Frequently fabricated into complex structures.
• Readily roller-formed, stamped, and drawn.
• Since 310 Stainless Steel rods work harden, severe forming operations should be followed by annealing.

WELDABILITY

• Austenitic stainless steel is generally considered weldable.
• Boasts weldability on par with 304 and 304L.
• Special care is imperative to accommodate a higher coefficient of thermal expansion to prevent warping and distortion.
• Standard welding processes for this grade include:
  • TIG-Welding
  • MAG-Welding Solid Wire
  • Arc Welding (E)
  • Laser Beam Welding
