| Why This Material Is Used in Chemical Industry | 1. Unmatched Hydrofluoric Acid Resistance:
– The only commercial alloy that resists corrosion from hydrofluoric acid at all concentrations and temperatures – Excellent resistance to all fluoride compounds, including hydrogen fluoride, fluorine gas and fluorides – Forms a protective copper fluoride film that prevents further corrosion in HF environments 2. Superior Seawater Corrosion Resistance: – Immune to chloride-induced stress corrosion cracking, pitting and crevice corrosion in seawater – Excellent resistance to biofouling, making it ideal for marine applications – Outperforms all stainless steels and most nickel alloys in seawater environments 3. Excellent Reducing Acid Resistance: – Good resistance to low-concentration sulfuric acid (up to 10% at boiling point) – Excellent resistance to hydrochloric acid (up to 5% at room temperature) – Good resistance to alkaline solutions, organic acids and salts 4. Broad Temperature Range Performance: – Maintains excellent mechanical properties from cryogenic temperatures (-253℃) up to 480℃ – Excellent toughness at low temperatures, making it suitable for cryogenic applications – Good thermal stability with no harmful phase precipitation during service 5. Superior Fabricability and Cost-Effectiveness: – Excellent formability, machinability and weldability, reducing fabrication costs – 30-50% lower material cost than Inconel and Hastelloy alloys – Long service life of 15-20+ years in most chemical environments |
