  • Alloy 347 (S34700) is stabilized stainless steel plate which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 347 stainless steel plate is stabilized by the addition of columbium and tantalum.

    Alloy 347 stainless steel sheet/plate is also advantageous for high temperature service because of its good mechanical properties. Alloy 347 stainless steel plate offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.

  • ADDITIONAL PROPERTIES OF 347/H STAINLESS STEEL SHEET/PLATE

    • Machinability
      Slightly tougher than 304 stainless, this material will produce the same tough stringy chips. The use of slow speeds and constant positive feeds will minimize this alloy's tendency to work harden.
    • Welding
      347 may be welded by all commonly used fusion and resistance methods. Oxyacetylene welding is not recommended. When necessary, use AWS E/ER347 filler metal.
    • Hot Working
      Working temperatures of 2100-2250 F (1149-1232 C) are recommended for forging, upsetting and other hot work processes. Do not work this alloy at temperatures below 1700 F ( 927 C). Material must be water quenched or fully annealed after working to reattain maximum corrosion resistance.
    • Cold Working
      Although this material requires higher initial forces than 304 stainless, it is quite tough and ductile and can be readily stamped, blanked, spun and drawn.
    • Annealing
      1850-2000 F (1010-1093 C), water quench. This procedure will result in maximum ductility. For maximum corrosion resistance, see the note on stabilizing anneal under corrosion.
    • Hardening
      This alloy does not harden by heat treating. Elevated properties may only be obtained through cold reduction.

  • SURFACE FINISH OF 347/H 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.
