347 Stainless Steel Sheet
What is 347 Stainless Steel Sheet?
347 stainless steel sheet is a chromium-nickel austenitic stainless steel enhanced with niobium (formerly known as columbium) stabilization. This addition effectively binds carbon, preventing chromium carbide formation and enabling the alloy to withstand temperatures between 800-1500°F without losing corrosion resistance. The material stands out for its exceptional resistance to intergranular corrosion, especially after exposure to temperatures in the chromium carbide precipitation range. It showcases superior creep and stress rupture strength compared to the 304/304L grades, alongside maintaining excellent toughness at low temperatures. Non-magnetic when annealed, 347 stainless steel is designed for high-temperature applications requiring both durability and resistance to corrosion, including environments where it might otherwise be susceptible to intergranular attack.
Features of 347 Stainless Steel Sheet
347 stainless steel sheet, recognized for its robust composition, is particularly tailored for environments that demand formidable resistance to intergranular corrosion, especially in the chromium carbide precipitation spectrum. This austenitic stainless steel is stabilized with niobium and tantalum, an innovative blend that significantly enhances its durability and corrosion resistance, ensuring its integrity in high-temperature applications. The 347 ss material showcases exceptional performance within a wide temperature range, maintaining its structural stability and resistance up to 816°C. This grade of steel is celebrated for its superior high-temperature properties, including remarkable creep and stress rupture strengths, making 347 steel an optimal choice for advanced engineering needs where both high temperature endurance and corrosion resistance are paramount.

347 Stainless Steel Finish & Application
The 347 stainless steel sheet stands out for its remarkable utility in demanding high-temperature environments, making it an exemplary choice for aerospace applications, such as manufacturing aircraft collector rings and exhaust stacks. Beyond its aeronautical applications, 347 stainless steel is also preferred for its performance in general high-temperature settings including boiler components, exhaust manifolds, jet engine parts, and mufflers for substantial engines, along with a variety of welded parts where its resistance to intergranular corrosion and high-temperature endurance are crucial. Despite its many industrial applications, it's important to note that 347 stainless steel is not typically selected for decorative purposes due to its less than ideal polishing characteristics, underscoring its role in functional rather than aesthetic applications.

5. What is the difference between them, 304 vs 347 stainless steel?
The primary distinction between 304 and 347 stainless steel lies in their response to high-temperature environments and their susceptibility to carbide precipitation, a form of corrosion that can degrade the metal's integrity when heated. While 304 stainless steel is celebrated for its widespread applications and robust corrosion resistance, its vulnerability to carbide precipitation under extended high-temperature exposure can limit its use in certain conditions. On the other hand, 347 stainless steel is specifically designed to overcome this challenge, incorporating stabilizing elements that provide exceptional resistance to carbide precipitation, making it ideal for use in high-temperature scenarios and in applications requiring significant welding.
Choosing between 304 and 347 stainless steel depends on the specific requirements of the application, particularly concerning temperature and welding needs. For projects that demand durability under high temperatures or involve extensive welding, 347 stainless steel is the preferable option. It's engineered to excel in situations where 304 stainless steel might not perform adequately, especially in long-term exposure to high temperatures or in welding-intensive projects, offering an enhanced safeguard against intergranular corrosion.
