Stainless Steel 347H Plates
Welcome to Amardeep Steel Centre LLP, your trusted partner in providing high-quality stainless steel products. Among our extensive range of offerings, we proudly present the 347H stainless steel plates. Renowned for their exceptional properties and versatile applications, these plates are a top choice for industries requiring superior strength and resistance to corrosion.
What is 347H Stainless Steel Plates?
347H stainless steel plates are austenitic stainless steel plates that contain a higher amount of carbon compared to the standard 347 grade. This increase in carbon content enhances the material’s high-temperature strength, making it ideal for applications involving prolonged exposure to high temperatures. The addition of niobium (columbium) further stabilizes the steel, preventing carbide precipitation and intergranular corrosion.
Properties of 347H Stainless Steel Plates
Understanding the properties of 347H SS plates is crucial for selecting the right material for your needs. Here are the key properties:
- High-Temperature Strength: The high carbon content in 347H grade stainless steel plates provides exceptional strength at elevated temperatures. This makes them suitable for environments where other steels might fail due to thermal stress.
- Corrosion Resistance: The niobium addition stabilizes the steel against chromium carbide formation, enhancing its resistance to intergranular corrosion. This is particularly beneficial in applications involving cyclic heating and cooling.
- Oxidation Resistance: 347H stainless steel plates exhibit excellent resistance to oxidation, maintaining their integrity and appearance even in high-temperature environments.
- Mechanical Properties: These plates have excellent mechanical properties, including high tensile and yield strength, making them durable and reliable for demanding applications.
- Weldability: Stainless steel plates 347H are known for their good weldability, allowing for ease of fabrication and assembly in various industrial processes.
Advantages of 347H Stainless Steel Plates
The benefits of using 347H SS plates are numerous, making them a preferred choice across various industries. Here are some of the key advantages:
- Superior High-Temperature Performance: 347H stainless steel plates can withstand prolonged exposure to high temperatures without losing their structural integrity, making them ideal for applications such as heat exchangers, furnace parts, and boiler components.
- Enhanced Durability: The combination of high strength and corrosion resistance ensures that stainless steel 347H plates have a long service life, reducing the need for frequent replacements and maintenance.
- Versatility: These plates are used in a wide range of industries, including chemical processing, petrochemical, power generation, and aerospace. Their versatility is due to their ability to perform reliably under extreme conditions.
- Cost-Effectiveness: Despite their higher initial cost, the durability and low maintenance requirements of 347H stainless steel plates make them a cost-effective solution in the long run.
