GENERAL PROPERTIES

• The 310S alloy, an austenitic stainless steel bar, excels with its outstanding high temperature resistance, while maintaining exceptional ductility and weldability. Its high chromium and nickel composition makes it a preferred choice for high temperature applications, offering formidable corrosion resistance, superb oxidation resistance, and impressive strength at temperatures soaring up to 2100°F. Distinguished by its performance, 310S outshines 304 and 309 stainless steel bars in most scenarios.

APPLICATIONS

• Higher alloyed stainless steels, like Alloy 310, deliver remarkable strength at elevated temperatures, coupled with extraordinary resistance to creep deformation and environmental damage. Consequently, Alloy 310 is extensively utilized in industries such as heat treatment and chemical processing. Notable 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 rods and pipes exhibit exceptional resistance to both corrosion and heat, even in the most challenging environments, ensuring longevity and reliability.

CORROSION RESISTANCE

• Remarkable corrosion resistance is assured.
• High chromium content ensures excellent aqueous corrosion resistance.
• Outstanding resistance at normal temperatures, with strong resistance to oxidizing and carburizing environments.

HEAT RESISTANCE

• Demonstrates excellent oxidation resistance in intermittent service in air at temperatures up to 1040°C and 1150°C in continuous service.
• Provides good resistance to thermal fatigue and cyclic heating.
• Widely used in applications where *** dioxide gas is present at elevated temperatures.
• Continuous use in the 425-860°C range is not recommended due to carbide precipitation, particularly if subsequent aqueous corrosion resistance is required.
• Typically employed at temperatures starting from approximately 800 or 900°C, beyond the effective range of 304H and 321 grades.

FABRICATION

• Ideal for heat treatment and process industries, thriving in high temperature and corrosive environments.
• Often crafted into complex structures with ease.
• Readily adaptable to roller-forming, stamping, and drawing processes.
• Due to work hardening, severe forming operations on 310 stainless steel rods should be followed by annealing.

WELDABILITY

• Austenitic stainless steel is widely recognized for its weldability.
• Comparable weldability to 304 and 304L grades.
• Special measures are required to counteract the higher coefficient of thermal expansion to prevent warping and distortion.
• Standard welding techniques applicable to this steel grade include:
  • TIG-Welding
  • MAG-Welding Solid Wire
  • Arc Welding (E)
  • Laser Beam Welding
