- Strong oxidation resistance
- Ideal for long-term thermal exposure
Applications
347 hot rolled stainless steel plates are widely used in:
- Boiler and pressure vessels
- Heat exchangers
- Petrochemical equipment
- Power plants
- Exhaust systems and furnace parts
- Aerospace components
Difference Between 347 and 347H
- 347: Standard carbon content, suitable for general corrosion resistance
- 347H: Higher carbon content, improved creep resistance at high temperatures
347H is preferred for long-term high-temperature service.
