Frequently Asked Questions
347 stainless steel contains niobium, which provides excellent resistance to intergranular corrosion, especially after welding. This makes it more suitable for high-temperature applications compared to 304 stainless steel, which is more commonly used for general-purpose applications.
347 stainless steel can operate continuously at temperatures up to 870°C (1600°F) while maintaining its corrosion resistance and mechanical properties. For intermittent service, it can withstand even higher temperatures.
