Overview
254SMO is an austenitic steel designed for maximum resistance to pitting and crevice corrosion. With high levels of chromium, molybdenum and nitrogen, 254SMO is especially suited for high chloride environments such as brackish water, seawater, pulp mill bleach plants and other high-chloride process streams. In new construction, 254SMO has been found in many cases to be technically adequate and much less costly substitute for nickel-based alloys and titanium. 254SMO is readily fabricated and welded.
Application
1. Ocean: marine structures, seawater desalination, seawater farming, seawater heat exchange, etc.
2. Environmental protection field: flue gas desulfurization device for thermal power generation, waste water treatment, etc.
3. Energy field: nuclear power generation, comprehensive utilization of coal, tidal power generation, etc.
4. Petrochemical field: oil refining, chemical and chemical equipment, etc.
5. Food field: salt making, soy sauce brewing, etc.
6. High concentration chloride ion environment: paper industry, various bleaching devices
