  • Corrosion Resistance:
    >>Withstands corrosive attacks better than any of the standard hardenable stainless steels.
    >>Comparable to Alloy 304 in most media.
    >>Corrosion resistant in some chemical, petroleum, dairy, and food process industries.
    >>Subject to crevice or pitting attack if exposed to stagnant sea water for any length of time.
  • Weldability:
    >>Successfully welded by most common fusion and resistance methods.
    >>Should not be joined by oxyacetylene welding.
    >>Generally no pre-heating required.
    >>Inter-pass temperature must be limited to 248°F.
    >>Better toughness is obtained in the weld after a complete heat treatment.
  • Elevated Temperature Use:
    >>Excellent resistance to oxidation to approximately 1100°F.
    >>Long-term exposure to elevated temperature can result in reduced toughness in the precipitation hardened conditions.
  • Processing – Hot Forming:
    >>To forge, heat uniformly to 2150 / 2200°F and hold for half hour per inch.
    >>Preferred temperature range for hot forming is at 650-900°F, while the steel is still austenitic.
    >>To ensure the best condition for the hardening operations, the forgings must be re-heat treated at 1875-1925°F.
    >>Cool forgings to below 90°F to ensure grain refinement.
  • Processing – Cold Forming:
    >>Alloy 17-4 is limited to mild operations since in the annealed (solution treated) condition the material is hard.
    >>For severe cold working the material should be heat treated to condition H1150. This will help prevent possible cracking.
    >>Bend radius in excess of 7T is often required.
    >>To improve stress corrosion resistance after cold forming, re-aging at the precipitation-hardening temperature is recommended.
  • Machinability:
    >>Can be machined in both solution-treated and precipitation-hardening conditions.
    >>Machining conditions may vary with hardness of material.
    >>High-speed tools or preferably carbide tools with standard lubrication are normally used.

*Not all finishes are available in all alloys – (contact Qukin for more information)

#1 FinishHot rolled, annealed and pickled.
#2D FinishA 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 FinishA semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
#3 FinishA semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
#4 FinishAlso 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 Finish150 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 FinishPolished finish achieved with the equivalent of a 240 grit abrasive. Finer grit lines and higher reflectivity than a No. 4 finish.
#7 FinishHighly reflective surface obtained with the equivalent of a 320 grit abrasive. Minimal grit lines.
No. 8 or True #8 mirrorThis 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 mirrorChemical 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 finish80 – 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.
