  • 17-4 PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 600℉ (316℃), good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This versatile material is widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.

    APPLICATIONS OF 17-4PH STAINLESS STEEL SHEET/PLATE

    Alloy 17-4 is commonly used for applications requiring high strength and a moderate level of corrosion resistance. Some applications that frequently use Alloy 17-4 include:

    • Aircraft
    • Nuclear waste casks
    • Paper mills
    • Oil fields
    • Mechanical components
    • Chemical process components
    • Food industry
    • Aerospace

  • ADDITIONAL PROPERTIES OF 17-4PH STAINLESS STEEL SHEET/PLATE

    • CORROSION RESISTANCE: The corrosion resistance of Alloy 17-4PH is comparable to 304 stainless steel in most environments, and in generally superior to the 400 series stainless steels. It is used in applications where the combination of moderate corrosion resistance and unusually high strength are required. Alloy 17-4PH has corrosion resistance comparable to 304L in some chemical, dairy, food, paper and petroleum applications.
    • WELDABILITY: Alloy 17-4PH can be readily welded by most standard processes including SMAW, GTAW, PAW and GMAW.
    • HOT FORMING: Heat uniformly at 1742-2192℉ (950-1200℃). A full solution anneal, cooling lower than 76℉ (25℃) and aging at the required temperature must occur after hot forming. The post forming heat treatment should be a function of the desired mechanical properties.
    • COLD FORMING: Alloy 17-4PH has limited cold forming properties. Cold forming can only be undertaken on plates in the fully annealed condition. Stress corrosion resistance is enhanced by re-aging at the precipitation hardening temperature after cold working.
    • CUTTING: Thermal cutting operations such as plasma cutting should be avoided Mechanical cutting operations such as bandsaw, abrasive waterjet, shearing and machining are preferred.

  • SURFACE FINISH OF 17-4PH 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.
