Stainless Steel 347 and 347H are popular austenitic stainless steel grades known for their excellent corrosion resistance, high-temperature strength, and durability. These grades are widely used in various industries, including chemical processing, petrochemicals, pharmaceuticals, and more. The availability of 347/347H sheets, plates, coils, and shims further enhances their applicability in diverse applications.
Stainless Steel 347 Sheet is a stabilized version of 304, containing niobium (columbium) for enhanced intergranular corrosion resistance. On the other hand, the SS 347H Plate is the high-carbon variant with improved high-temperature strength. The key alloying elements include chromium, nickel, and niobium, ensuring robust performance in harsh environments.
SS 347/347H Sheets and Plates are available in various thicknesses and dimensions to meet specific project requirements. These components offer exceptional resistance to corrosion in acidic and alkaline environments, making them suitable for use in chemical processing plants and similar industries. Their versatility extends to applications where elevated temperatures are a concern, such as in heat exchangers and furnace components.
Table Of Content
Stainless Steel 347 Coils find applications in manufacturing processes where continuous lengths of material are required. These coils provide the same corrosion resistance and high-temperature stability as sheets and plates, making them indispensable in industries like automotive, aerospace, and construction. The SS 347H coils can be easily formed and fabricated into different shapes to suit the needs of various projects.
Stainless Steel 347H Shims serve these purposes while offering corrosion resistance and stability in demanding conditions. Commonly used in the oil and gas industry, chemical plants, and power generation facilities, these SS 347 shims provide reliable performance under high-pressure and high-temperature conditions.
Features and Benefits:
Corrosion Resistance: The high chromium and nickel content in SS 347/347H grades ensures resistance to corrosion in aggressive environments.
High-Temperature Stability: These alloys exhibit excellent strength and oxidation resistance at elevated temperatures, making them suitable for applications involving heat.
Stabilized Structure: The addition of niobium in SS 347 imparts stability against sensitization and intergranular corrosion.
