product details

321/321H stainless steel pipe is a type of pipe made from austenitic stainless steel alloys that are stabilized with titanium, offering enhanced resistance to high-temperature corrosion. It combines excellent corrosion resistance with good strength and weldability.
Key features:
Corrosion resistance: Resists corrosion in various environments, including oxidizing and acidic conditions.
High-temperature strength: Maintains strength at elevated temperatures up to 816°C (1500°F).
Intergranular corrosion resistance: Resists corrosion along grain boundaries, even after exposure to temperatures within the chromium carbide precipitation range (800-1500°F).
Good weldability: Can be easily welded using common stainless steel welding techniques.
Common applications:
High-temperature exhaust systems.
Chemical processing equipment.
Aerospace components.
Food processing equipment.
Pharmaceutical manufacturing.
Marine environments.
Power generation.
