Product description
Stainless Steel Grade 321 is a chromium-titanium alloyed austenitic stainless steel renowned for its exceptional resistance to intergranular corrosion and high-temperature oxidation. This grade is widely utilized in industries where materials are exposed to temperatures ranging from 425°C to 860°C, making it a critical component in heat exchangers, furnace parts, and exhaust systems.
Key Features
- Excellent High-Temperature Strength: Maintains mechanical integrity and corrosion resistance at elevated temperatures.
- Intergranular Corrosion Resistance: Titanium stabilization prevents grain boundary attack during welding or heat treatment.
- Weldability: Suitable for various welding methods without significant risk of sensitization.
- Form Availability: Supplied in sheet, plate, coil, strip, pipe, tube, bar, and wire forms to suit diverse fabrication needs.
Applications
Grade 321 is the preferred choice for components in chemical processing, petrochemicals, and power generation. It is commonly used for heat exchanger tubes, boiler furnace components, and structural parts in high-heat environments. Its ability to withstand thermal cycling makes it ideal for exhaust systems and heat treatment equipment.
