  • Alloy 254 SMO is a very high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. Alloy 254 SMO is substantially stronger than the common austenitic grades, with strength nearly twice that of 300 series stainless steel. It is also characterized by high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen, Alloy 254 SMO is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. In some applications it has even been found to be a more cost effective substitute for high nickel and titanium alloys.

    APPLICATIONS OF ALLOY 254 STAINLESS STEEL SHEET/PLATE

    • Petroleum production
    • Saltwater handling
    • Food and chemical processing equipment
    • Pulp mill bleach systems
    • Flue gas desulphurization scrubbers
    • Tall oil distillation columns
    • Offshore oil & gas production equipment
    • Desalination equipment
  • ADDITIONAL PROPERTIES OF ALLOY 254 STAINLESS STEEL SHEET/PLATE

    • Corrosion Resistance
      >>Excellent resistance to pitting and crevice corrosion due to its high chromium, molybdenum, and nitrogen content
      >>Has a very low carbon content, which means there is very little risk of carbide precipitation during heating
      >>Possesses very good resistance in water containing chlorides, therefore, it is suitable for use in seawater as it can be exposed to it for prolonged periods without suffering from crevice corrosion
    • Weldability
      >>Possesses good weldability
      >>Should be done without pre-heating
      >>If correctly performed, there will be no need for any subsequent heat treatment
      >>Has low thermal conductivity and high thermal expansion so must minimize distortion of welded joint
      >>Welding without filler metal results in poor strength properties
    • Machinability
      >>High work hardening rate combined with a lack of sulfur makes it very difficult to machine
      >>Slow speeds, sharp tools, positive feeds, over-powered machine tools, and ample lubrication offer the best results
  • SURFACE FINISH OF Alloy 254 STAINLESS STEEL SHEET/PLATE :
    *Not all finishes are available in all alloys - (contact Yieh United Sales for more information)

    #1 Finish Hot rolled, annealed and pickled.
    #2D Finish A uniform, dull silver gray mill finish that is applied to thinner stainless steel coils,the thickness of which has been reduced by cold rolling.
    #2B Finish A semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
    #3 Finish A semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
    #4 Finish Also called brushed, directional or satin finish. A is characterized by fine polishing grit lines that are uniform and directional in appearance. The final abrasive used in the process is 150 to 220 grit.
    #4 Satin Brush Finish 150 to 180 grit finish A fine directional polish, typically used in the washroom accessories industry. Most 3.5″ floppy diskette cover plates have this finish.
    #6 Finish Polished finish achieved with the equivalent of a 240 grit abrasive. Finer grit lines and higher reflectivity than a No. 4 finish.
    #7 Finish Highly reflective surface obtained with the equivalent of a 320 grit abrasive. Minimal grit lines.
    No. 8 or True #8 mirror This is the most reflective mirror finish on the market. All of the polishing, or “grit,” lines from the preliminary polishing operations are removed. The look is that of a glass mirror. Sometimes referred to as a non directional mirror finish, Super 8, No. 9, Perfect No. 10, and even No. 12 mirror.
    CMP Super #8 mirror Chemical Mechanical Polished Super #8 mirror finished sheets are guaranteed to be free from any manufacturing defects. This product represents the ultimate in mirror polished stainless steel. It is available as a single-sided or double-sided mirror polished sheet.
    Hairline finish 80 – 140 grit finish A well defined directional polish. Starting base substrate is a No. 4 finish sheet; these sheets are polished to provide a “continuous long grain” hairline look. A finish which is popular with architects for its aesthetic, it is equally popular with fabricators due to it’s ease of fabrication and finish matching properties after welding operations.
