Product Description
347 Stainless Steel Pipe Overview
347 Stainless Steel Pipe is a columbium-stabilized austenitic stainless steel offering excellent corrosion resistance, particularly in strong oxidizing conditions. It provides superior resistance to intergranular corrosion after exposure to temperatures between 800-1500°F (427-816°C), with good oxidation resistance and creep strength up to 1500°F (816°C).
Key Benefits
- Higher creep stress and rupture properties compared to 304 stainless steel
- Ideal for high-temperature service applications
- Overcomes sensitization and intergranular corrosion concerns
- Suitable for ASME Boiler and Pressure Vessel Code applications
- Superior overall corrosion resistance compared to 304/304L
- Excellent mechanical properties and low-temperature toughness
- Available in high-carbon version (347H) for enhanced performance
Typical Applications
- Heat exchangers
- High-temperature steam service
- High-temperature chemical processing
