Stainless Steel 347H Pipe
Welcome to Amardeep Steel Centre, your trusted partner for high-quality stainless steel solutions. Our Stainless Steel 347H Pipes are engineered to meet the rigorous demands of various industries, offering exceptional performance, durability, and resistance to extreme conditions. This page provides comprehensive information about stainless steel 347H pipe, its properties, and its applications to help you make an informed decision.
What is 347H Stainless Steel?
347H stainless steel is an austenitic stainless steel that contains columbium (also known as niobium). This addition enhances its resistance to intergranular corrosion and high-temperature stability. It is a high-carbon version of 347 stainless steel, designed to provide better high-temperature strength and creep resistance. These characteristics make 347H an excellent choice for applications requiring prolonged exposure to high temperatures.
347H Stainless Steel Properties
Understanding the properties of 347H stainless steel is crucial for selecting the right material for your needs. Here are the key properties of 347H stainless steel:
- High-Temperature Strength: 347H stainless steel maintains its strength and structural integrity at temperatures up to 1500°F (815°C). This makes it ideal for high-temperature applications.
- Corrosion Resistance: The addition of columbium stabilizes the steel and provides resistance to intergranular corrosion, even after welding. This makes it suitable for environments where the material is exposed to corrosive elements.
- Creep Resistance: The high carbon content in 347H stainless steel enhances its creep resistance, making it suitable for applications where the material is subjected to stress at high temperatures.
- Oxidation Resistance: 347H stainless steel exhibits excellent oxidation resistance, ensuring long-term performance even in oxidizing environments.
- Weldability: Despite its high carbon content, 347H stainless steel is readily weldable, making it versatile for various fabrication processes.
Advantages of Using Stainless Steel 347H Pipe
347H stainless steel pipes offer several key benefits, making them ideal for various industrial applications:
- High-Temperature Performance: Withstanding temperatures up to 1500°F (815°C), 347H stainless steel pipes maintain their strength and integrity, making them suitable for high-temperature environments like power generation and petrochemical processing.
- Corrosion Resistance: The addition of columbium (niobium) enhances resistance to intergranular corrosion, ensuring longevity and reliability in corrosive environments, reducing maintenance needs.
- Creep Resistance: High carbon content improves creep resistance, allowing the pipes to endure prolonged stress at elevated temperatures, essential for applications such as boilers and heat exchangers.
- Weldability: Despite their high carbon content, 347H stainless steel pipes are easily weldable, facilitating fabrication, repairs, and modifications without compromising material integrity.
- Durability and Longevity: Combining high-temperature strength, corrosion resistance, and oxidation resistance, these pipes offer exceptional durability and a long service life, leading to lower replacement and maintenance costs.
