SMO 254 Round Bars
12.70mm - 101.60mm
SMO 254 is a high-alloy stainless steel with a combination of excellent corrosion resistance and high strength. It is specifically designed to resist pitting, crevice corrosion, and stress corrosion cracking, making it ideal for use in aggressive environments such as marine, chemical processing, and other high-stress industries. SMO 254 round bars are widely used in applications that require superior resistance to chloride-induced corrosion, high temperatures, and mechanical stress.
SMO 254 Round Bars available in diameters ranging from 12.70mm to 101.60mm.

Applications
- Chemical Processing: Used in reactors, heat exchangers, and piping systems that handle aggressive chemicals, acids, and alkalis.
- Marine Industry: Ideal for use in seawater applications such as desalination plants, offshore platforms, and marine components exposed to highly corrosive seawater.
- Power Generation: Used in power plants for heat exchangers, condensers, and other components exposed to high temperatures and aggressive environments.
- Heat Exchangers: Due to its excellent resistance to scaling and corrosion in heat transfer applications, SMO 254 is used in heat exchangers for both industrial and marine environments.
- Desalination Plants: SMO 254 is highly resistant to seawater, making it suitable for use in desalination plants that process seawater into potable water.
