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
