Zeron 100 Overview

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. The copper content (min. 0.5, max 1.0) permits excellent resistance to corrosion in many non-oxidizing acids.

What are the characteristics of Zeron 100, super duplex stainless steel?

Guaranteed corrosion performance (PREn ≥ 40)
High resistance to pitting and crevice corrosion
Excellent resistance to stress corrosion cracking in both chloride and sour environments
High resistance to erosion corrosion and corrosion fatigue
Excellent mechanical properties
Possibility for weight reduction over austenitic, standard duplex and nickel base alloys
Good weldability
