Advantages of Stainless Steel 347H Fasteners

  • Corrosion resistance: Stainless steel 347H contains high levels of chromium and nickel, which gives it excellent corrosion resistance, especially in tropical environments. This makes it suitable for corrosive environments such as chemical processing and petrochemical and marine applications.
  • Higher thermal conductivity: The higher carbon content of 347H increases its thermal conductivity and enhances its insensitivity during heat treatments, such as welding or high temperatures. This property makes it ideal for applications where fasteners are exposed to high temperatures, such as boilers, heat exchangers and exhaust systems.
  • Durability: Stainless steel 347H fasteners are known for their durability, even under harsh operating conditions. They resist deformation, cracking and wear and have a longer lifespan than other materials.
  • Easy to manufacture: Stainless steel 347H can be easily manufactured in a variety of shapes and sizes, making it suitable for a wide range of fasteners such as bolts, nuts, screws, washers etc. Its malleability allows customization to meet specific application requirements of various types.
  • Hygienic properties: Stainless steel 347H is inert and easy to clean, making it suitable for use in areas where hygiene is important, such as in the food and pharmaceutical industries. Its smooth surface seals bacteria grow on the edge, creating a clean environment.

How to Choose the Right Stainless Steel 347H Fasteners

  • Corrosion Resistance: Stainless steel 347H provides excellent corrosion resistance, especially in high-temperature environments. Your fasteners should check for corrosion and ensure stainless steel 347H suits those conditions.
  • Heat Resistance: Stainless steel 347H is specially designed for high-temperature applications, with a maximum service temperature of approximately 800°C (1472°F). Determine the operating temperature of your application to ensure that steel easily 347H will cope.
  • Strength requirements: Consider the mechanical requirements for your fasteners, including tensile strength, yield strength, and stiffness. Stainless steel 347H provides excellent strength and toughness, suitable for many industrial applications.
  • Fastener Type: Select the appropriate fastener (e.g., bolts, nuts, screws, washers) based on the specific requirements of your application. Ensure the fastener type selected meets design and assembly requirements.

Are Stainless Steel 347H Fasteners magnetic?

Stainless steel 347H fasteners are generally non-magnetic in their annealed state due to their austenitic structure. However, they can become partially magnetic after cold working or during fabrication processes. Magnetic properties may vary depending on the specific manufacturing conditions and alloy composition.

FAQ (Frequently Asked Questions)

Are Stainless Steel 347H Fasteners resistant to corrosion?

Yes, stainless steel 347H fasteners offer excellent resistance to corrosion, particularly in high-temperature environments. They contain higher levels of chromium, nickel, and molybdenum, providing superior resistance to corrosion from acids, alkalis, and other corrosive agents, making them suitable for demanding industrial applications.

Are stainless steel 347H fasteners susceptible to galvanic corrosion?

Stainless steel 347H fasteners are generally resistant to galvanic corrosion due to their high chromium content, which forms a protective oxide layer. However, in certain aggressive environments or when coupled with dissimilar metals, galvanic corrosion may occur. Proper material selection and insulation techniques can mitigate this risk.

Can Stainless steel 347H fasteners be recycled after use?

Yes, stainless steel 347H fasteners are highly recyclable. They can be collected, sorted, and processed through melting and refining processes to produce new stainless steel products. Recycling stainless steel helps conserve natural resources, reduce energy consumption, and minimize environmental impact, making it an environmentally sustainable choice.
