Annealed Soft 0.03mm Alloy 20 Ultra Thin Wire For Chemical Processing Plant
- Superior Sulfuric Acid Resistance
- Practical Immunity to Chloride Stress Corrosion Cracking
- Excellent Pitting & Crevice Corrosion Resistance
- Weldable Without Post-Weld Heat Treatment
- Good Mechanical Properties
Alloy 20 is a nickel‑iron‑chromium austenitic alloy with outstanding resistance to sulfuric, phosphoric, and nitric acids. Its ~33% nickel content provides practical immunity to chloride stress corrosion cracking — a critical advantage over 316L. Molybdenum, copper, and niobium enhance pitting resistance and allow welded fabrication without post‑weld heat treatment.
