ASME SA213 TP321 S32100 Stainless Steel Seamless Tube for Superheater Application

• 1. High-Temperature Endurance
• Can stably work under superheater’s high-temperature conditions (e.g., common 500 - 800°C). Titanium in the alloy stops “sensitization”, avoiding intergranular corrosion even after long-term heat exposure, ensuring effective steam heating.
• 2. Corrosion Resistance
• Resists oxidation from superheater’s oxygen-rich gases and steam. Also fends off flue gas-related corrosive substances, reducing damage and extending tube service life.
• 3. Mechanical Reliability
• Under high pressure and thermal stress in superheaters, it has good creep and stress-rupture resistance. Maintains shape and structure, preventing deformation or rupture-caused failures.
