347H is an austenitic stainless steel developed from 347 with optimized high-temperature performance. It offers superior high-temperature strength and microstructural stability, making it suitable for piping systems operating continuously under high-temperature and high-pressure conditions. The addition of niobium effectively enhances intergranular corrosion resistance and maintains good microstructural stability under high-temperature operating conditions.
- Suitable for high-temperature, pressurized systems: Better suited for long-term high-temperature operating environments
- Inventory support for more efficient procurement: Over 3,000 tons in stock for faster lead time responses
- Clear Certification System: Certified under PED, ISO, and AD2000 standards
- Traceable Quality Process: Comprehensive verification from raw materials to pre-shipment inspection
- Ideal for Industrial B2B Procurement: Supports standardized specification confirmation and stable bulk supply
347H stainless steel seamless tubes are primarily used in industrial systems with high requirements for high-temperature strength, heat resistance, and pressure-bearing performance, including:
- Boiler superheaters and reheaters
- Heat exchangers
- High-temperature steam pipelines
- Heat transfer systems in petrochemical plants
- Raw Material Inspection: Strict verification of chemical composition and material certificates
- In-Process Quality Control: Comprehensive process monitoring during manufacturing
- 100% Pre-Shipment Inspection: Complete dimensional, surface, and mechanical property verification
