Product Description
The U Bend Return is a 180-degree elbow made from ASTM A403 WP347H stainless steel, available in both long and short radius configurations. Grade 347 is an austenitic stainless steel stabilized with niobium for enhanced resistance to intergranular corrosion, making it particularly effective in high-temperature environments.
This material exhibits excellent mechanical properties and corrosion resistance, including:
- Superior resistance to creep and stress rupture at elevated temperatures
- Excellent intergranular and general corrosion resistance
- Good oxidation resistance up to 1500°F (816°C) in intermittent service and 1650°F (899°C) in continuous service
