Stainless Steel 321 Pipe
Properties of 321 Stainless Steel Pipes
- Corrosion Resistance: One of the standout properties of 321 stainless steel is its superior resistance to intergranular corrosion, thanks to the addition of titanium. This makes it an ideal choice for applications where the material will be exposed to high temperatures.
- High-Temperature Strength: 321 grade stainless steel exhibits remarkable strength and toughness at elevated temperatures. It can withstand prolonged exposure to temperatures up to 1500°F (816°C) without losing its mechanical properties.
- Durability: The durability of 321 stainless steel makes it suitable for a wide range of applications, including chemical processing, aerospace, and heat treatment industries.
- Formability and Weldability: This stainless steel grade is easily formed and welded using conventional techniques, making it versatile and easy to work with.
- 321 Stainless Steel Hardness: The hardness of 321 stainless steel is typically in the range of 217-241 HB (Brinell Hardness), providing a balance between strength and ductility.
Applications of 321 Stainless Steel
Due to its unique properties, 321 stainless steel is widely used in various industries:
- Aerospace: Ideal for exhaust systems, firewalls, and other high-temperature components.
- Chemical Processing: Used in equipment and piping for handling chemicals at high temperatures.
- Food Processing: Suitable for food production equipment due to its corrosion resistance.
- Pharmaceutical: Utilized in production equipment where hygiene and corrosion resistance are crucial.
- Heat Treatment: Perfect for furnace components, heat exchangers, and other high-temperature applications.
