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 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.
What are the characteristics of Zeron 100, super duplex stainless steel?
• Guaranteed corrosion performance (PREn ≥ 40)
• Excellent corrosion resistance in mineral acids such as hydrochloric and sulfuric
• 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
