Zeron* 100(UNS S32760)


Zeron 100, super duplex stainless steel, is a highly  alloyed stainless steel designed for use in aggressive environments. High  strength, toughness, excellent corrosion resistance and its resistance to  corrosion in a wide range of organic and inorganic acids are just a few  characteristics that make this duplex stainless steel attractive to a variety  of industries. Lastly, it is highly resistant to strong alkalis and resists  corrosion in many non-oxidizing acids.

Usage of this super duplex stainless steel is not  recommended when it involves extended exposure to temperatures greater than  572° F. This exposure causes a substantial reduction in toughness.

Notice the chemical composition of duplex 2507 and  Zeron 100 are similar however; Zeron 100 contains slightly more copper and  tungsten.  The copper content (min.  0.5, max 1.0) permits excellent resistance to corrosion in many non-oxidizing  and mineral acids like hydrochloric and sulfuric acid.
