In this guide, we delve into the properties of Zeron 100, its chemical composition, applications, and comparisons with similar materials like 2507.
What Is Zeron 100?
Zeron 100 is a super duplex stainless steel alloy developed by Rolled Alloys. It features a balanced dual-phase microstructure consisting of equal parts austenite and ferrite, which provides superior mechanical properties and corrosion resistance. Its unique chemical composition includes:
- Chromium (Cr): 24-26%
- Nickel (Ni): 6-8%
- Molybdenum (Mo): 3-4%
- Copper (Cu): 0.5-1%
- Tungsten (W): 0.5-1%
- Nitrogen (N): 0.2-0.3%
- Iron (Fe): Balance.
This composition ensures high resistance to pitting, crevice corrosion, stress corrosion cracking, and erosion corrosion in chloride-rich environments.
