Features:

• Austenitic stainless steel known for its high-temperature strength and corrosion resistance in oxidizing and reducing environments.
• Widely used in high-temperature applications such as heat treatment furnaces, combustion chambers, and exhaust systems.
• Offers excellent oxidation resistance at temperatures up to 1150°C (2100°F) in continuous service and 1035°C (1900°F) in intermittent service.
• Resistant to sulfidation and carburization in high-temperature environments, making it suitable for use in petrochemical and chemical processing industries.
• Provides good resistance to thermal fatigue and cyclic heating and cooling, ensuring reliable performance in demanding thermal environments.
• Non-magnetic in the annealed condition but may become slightly magnetic after cold working.

Heat Treatment:

• Annealing: Heat to 1040-1150°C (1900-2100°F), followed by rapid cooling in air or water to avoid sensitization.
• Stress Relieving: Heat to 1050°C (1920°F) for 1-2 hours, followed by air cooling.
• Hardening: Cannot be hardened by heat treatment, but cold working can increase hardness and strength.
• Welding: Suitable for welding using common methods such as TIG, MIG, and resistance welding. Preheating and post-weld annealing may be required to avoid sensitization and maintain corrosion resistance.
