Fabrication Characteristics
Grade 904L stainless steel features high purity with low sulphur content, enabling machining using standard methods. The material can be readily cold-bent to small radii. While subsequent annealing is typically unnecessary, it is recommended for fabrication under severe stress corrosion cracking conditions.
Applications
- Wiring in electrostatic precipitators
- Oil refinery components
- Seawater cooling devices
- Gas scrubbing plants
- Pulp and paper processing industries
- Acetic, phosphoric and sulphuric acid processing plants
