Heat Treatment
Heat Treatment
- Annealing
- Temperature: 1010°C – 1120°C (1850°F – 2050°F)
- Process: Heat and cool slowly in air to relieve stress and improve ductility.
- Solution Annealing
- Temperature: 1038°C – 1149°C (1900°F – 2100°F)
- Process: Heat to dissolve carbides, then cool rapidly to enhance corrosion resistance.
- Stabilizing Annealing
- Temperature: 870°C – 900°C (1600°F – 1650°F)
- Process: Heat and air cool to stabilize carbides and prevent corrosion.
- Quenching, Tempering, Normalizing: Not used for 347H stainless steel due to its stable austenitic structure.
Characteristic
Characteristic
347H stainless steel pipe, sheet, and bar offer excellent heat resistance, corrosion resistance, and durability. Niobium stabilization prevents carbide precipitation, ensuring weldability with minimal cracking risk, making them ideal for demanding industrial applications.
- Pipe: Best for high-strength, stable, and corrosion-resistant applications.
- Sheet: Highly formable and low maintenance for versatile uses.
- Bar: Easily machinable for precision components.
