LDX 2101 is a duplex (austenitic-ferritic) stainless steel with relatively low contents of alloying elements. The grade has high mechanical strength, similar to that of other duplex grades. Its good corrosion resistance is on par with that of most standard stainless steel grades. Combined, these properties can be utilized to optimise design with respect to strength, maintenance, durability and long-term cost efficiency.

  • Corrosion Resistance
    >>generally good corrosion resistance
    >>suitable for use in a wide range of general-purpose applications and environments.
  • Pitting and crevice corrosion
    >>resistance to pitting and crevice corrosion increases with the content of chromium, molybdenum and nitrogen in the steel.
    >>resistance to these types of corrosion, which are mainly caused by chloride containing environments, is good due to the grade’s high chromium and nitrogen content.
  • Atmospheric corrosion
    >>strongly linked to resistance to uniform corrosion and localised corrosion such as pitting and crevice corrosion.
    >>sufficiently resistant in most environments.
  • Stress corrosion cracking
    >>Like all duplex stainless steels, LDX 2101 shows good resistance to chloride-induced stress corrosion cracking (SCC).
  • Heat Treatment
    >>Plate, sheet and coil are normally delivered in heat treated condition. If additional heat treatment is needed after further processing the following is recommended.
  • Hot Forming
    >>Hot forming is performed in the temperature range 1100–900°C (2010-1650oF) and should be followed by solution annealing. It should, however, be observed that the strength is low at high temperatures.
  • Cold Forming
    >>Due to the high proof strength of duplex material, greater working forces than those required for austenitic steel are usually needed for cold forming.
    >>LDX 2101 is suitable for most forming operations used in stainless steel fabrication.
    >>Due to the grade’s higher mechanical strength and lower toughness, operations such as deep drawing, stretch forming and spinning are more difficult to perform than with austenitic steel.
  • Welding
    >>LDX 2101 has a good weldability and can be welded using the same processes used for other duplex steels.
    >>In general the recommendations for welding duplex steels also apply for LDX 2101, however, the restrictions in arc energy are less tight than for conventional duplex steels due to the grade’s low alloy content and high nitrogen level.

*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.
