PROPRIETARY 304L (18-9L) Heat Treatments
- Annealing
After cold forming (work hardening) and after welding an annealing treatment for a couple of minutes at 1050 ± 25°C followed by air cooling water quenching, restores the microstructure (recrystallisation and dissolution of carbides) and eliminates internal stresses.
Pickling
Nitric-Hydrofluoric acid mixture (10%HNO3 + 2% HF) at ambient temperature or up to 60°C.
Sulfuric-nitric acid mixture (10% H2SO4 + 0.5%NHO3) at 60°C
Descaling pastes for weld areas.
Passivation
- 20-25% HNO3 solution (36° Baumé) at 20°C.
- Passivating pastes for weld zones.
