310 Stainless Steel Plates
Grade 310 is an austenitic stainless steel with high chromium and nickel content, providing superior oxidation resistance at elevated temperatures.
Key Features
- High-Temperature Resistance: Performs well at temperatures up to 1150°C in continuous service.
- Oxidation Resistance: Excellent resistance to oxidation in mildly cyclic conditions.
- Good Mechanical Strength: Retains strength even at high temperatures.
- Ease of Fabrication: Readily weldable and formable.
Applications
- Heat exchangers
- Furnace components
- Kilns and burners
- Thermal processing equipment
- Petrochemical plants
310S Stainless Steel Plates
Grade 310S is the low-carbon version of 310, designed for improved weldability and reduced risk of intergranular corrosion.
Key Features
- Low Carbon Content: Reduces carbide precipitation during welding.
- Corrosion Resistance: Comparable to 310 with added weldability.
- High-Temperature Stability: Suitable for continuous service at elevated temperatures.
Applications
- Flare stacks
- Heat treatment equipment
- Cryogenic structures
- Power plant components
321 Stainless Steel Plates
Grade 321 is a titanium-stabilized stainless steel, offering improved resistance to intergranular corrosion after welding or exposure to high temperatures.
Key Features
- Resistance to Intergranular Corrosion: Excellent in high-temperature applications.
- Enhanced Creep Strength: Suitable for prolonged exposure to elevated temperatures.
- Weldability: Retains strength and corrosion resistance during welding.
- Versatility: Ideal for both structural and high-temperature environments.
Applications
- Heat exchangers
