Stainless Steel 347 and 347H wires are corrosion-resistant, heat-resistant, and versatile materials widely used in various industrial applications. These wires belong to the austenitic stainless steel family and are characterized by their excellent mechanical properties and high resistance to corrosion, making them suitable for challenging environments.
Chemical Composition: Stainless Steel 347 and 347H wires are primarily composed of iron, chromium, nickel, and a small amount of columbium (niobium). The addition of columbium provides enhanced stabilization against chromium carbide precipitation, which occurs at elevated temperatures. This stabilization feature is particularly beneficial for high-temperature applications.
Corrosion Resistance: One of the key attributes of Stainless Steel 347 and 347H wires is their exceptional corrosion resistance. These wires exhibit resistance to intergranular corrosion, which is the deterioration of the material at grain boundaries. This property makes them suitable for applications involving exposure to corrosive environments, such as chemical processing, petrochemical, and aerospace industries.
Table Of Content
Heat Resistance: Stainless Steel 347 and 347H wires are designed to withstand high temperatures. The addition of niobium not only provides stabilization against sensitization but also contributes to the materials' ability to maintain mechanical properties at elevated temperatures. This makes them ideal for use in applications where exposure to extreme heat is a concern, such as in heat exchangers and furnace components.
Versatility in Applications: The versatility of Stainless Steel 347 and 347H wires extends to various industrial applications. They are commonly used in the manufacturing of heating elements, boiler tubes, chemical processing equipment, and aircraft exhaust systems. Their ability to maintain structural integrity in harsh conditions makes them a preferred choice for critical applications.
Weldability and Formability: Stainless Steel 347 and 347H wires are known for their excellent weldability and formability. They can be easily welded using common welding methods, and their formability allows for the fabrication of intricate components. This makes them a practical choice for a wide range of fabrication processes.
