  • This straight chromium stainless steel offers reasonable corrosion resistance and high mechanical characteristics. The 403 Series offers heat resistance and a scaling temperature of about 1300°F. It is a corrosion and heat resistant 12% Cr martensitic stainless steel. This alloy offers a wide range of mechanical properties that are obtainable by appropriate heat treatments. It is easily hardened by oil, fan or air cooling and may be tempered at temperatures of up to 1350°F (732°C) to improve fracture toughness. Oil or fan cooling is required in thicker sections.

    APPLICATIONS OF 403 STAINLESS STEEL SHEET/PLATE

    • Compressor blades
    • Turbine parts
  • ADDITIONAL PROPERTIES OF 403 STAINLESS STEEL SHEET/PLATE

    • Corrosion Resistance
      >>High degree of resistance to atmospheric corrosion because of its ability to form a tightly adherent oxide film.
      >>Maximum corrosion resistance is obtained by hardening and polishing.
      >>Not recommended for use in severely corrosive environments.
    • Oxidation Resistance
      >>Resists oxidation up to 1400°F (760°C).
      >>Temperature should not exceed 1200-1300°F (649-704°C) in continuous service.
    • Forging or Rolling
      >>Starting temperature between 2000°F and 2100°F is recommended for forging, with a finishing temperature recommended above 1400°F .
      >>Final forging temperatures as low as 1300°F, if care is taken not to rupture steel.
      >>Better mechanical properties obtained in forged and tempered condition in lower temperatures.
    • Annealing
      >>May be annealed at 1500-1650°F, followed by a slow cool to 1100°F , and a final air cool.
    • Hardening
      >>Material may be fully hardened by oil quenching from 1650-1800°F.
      >>Light sections may be hardened by air or fan cooling.
      >>Alloy will harden, to varying degrees, when cooled from temperatures above 1500°F.
    • Tempering
      >>May be done at a temperature between 400°F -1400°F.
      >>Advisable to avoid the 800°F – 1100°F range due to a decrease in impact properties and corrosion resistance.
      >>Strength and hardness decrease in the 800°F – 1100°F while ductility and toughness increase as the tempering temperature is raised.


  • SURFACE FINISH OF 403 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.
