- Corrosion Resistance: Performs well in moderately aggressive environments.
- High Strength: Retains mechanical properties at elevated temperatures.
- Versatility: Suitable for industrial and commercial high-temperature applications.
Applications
- Furnace components
- Heat exchangers
- Kilns and refractories
- Petrochemical processing equipment
- Power plant boilers
310S Stainless Steel Sheets
Grade 310S is a low-carbon variant of 310 stainless steel, offering enhanced weldability and reduced risk of carbide precipitation. It is ideal for applications where welding is critical.
Key Features
- Low Carbon Content: Improves resistance to intergranular corrosion.
- Weldability: Better suited for fabrication and welding compared to 310.
- Corrosion Resistance: Comparable to 310 with enhanced resistance to sensitization.
- High-Temperature Performance: Effective in temperatures up to 1050°C in continuous service.
Applications
- Welded heat exchangers
- Furnace components
- Radiant tubes
- Chemical processing equipment
- Food processing equipment
321 Stainless Steel Sheets
Grade 321 is stabilized with titanium to improve resistance to intergranular corrosion, making it ideal for high-temperature and welding applications.
Key Features
- Stabilized Alloy: Titanium addition prevents carbide precipitation during welding.
- High-Temperature Strength: Performs well in temperatures up to 870°C.
- Corrosion Resistance: Superior resistance to oxidation and scaling in aggressive environments.
- Good Formability: Easily formed and fabricated into complex shapes.
Key Features
- Aerospace exhaust systems
- High-temperature chemical processing
- Expansion joints
- Thermal oxidizers
- Heat exchangers and boilers
