| Why These Materials Are Used in Chemical Industry | 1. Unmatched Chloride Corrosion Resistance:
– Immune to chloride-induced pitting, crevice corrosion and stress corrosion cracking – Resists corrosion in seawater, brines and chloride-containing process fluids up to 200℃ – Eliminates the most common failure mode in chemical processing equipment 2. Superior Acid Resistance: – Gr.1/2/3: Excellent resistance to oxidizing acids (nitric acid, chromic acid) and neutral solutions – Gr.7/16: Superior resistance to reducing acids (hydrochloric acid, sulfuric acid) and crevice corrosion – Gr.12: Excellent resistance to high-temperature acids and salt solutions – Outperforms stainless steel by 10-20 times in most acid environments 3. Excellent Caustic and Alkali Resistance: – Resists corrosion in sodium hydroxide, potassium hydroxide and other alkaline solutions – Ideal for chlor-alkali production and caustic handling systems – No stress corrosion cracking in high-concentration caustic solutions 4. Wet Chlorine Resistance: – The only commercial material that can reliably withstand wet chlorine gas – Forms a stable protective oxide layer in chlorine environments – Essential for chlorine production and processing equipment 5. Superior Cost-Effectiveness: – While initial cost is 3-5x higher than 316L, 10-20x longer service life reduces total cost of ownership by 60-80% – Eliminates costly annual maintenance and replacement of stainless steel components – No need for protective coatings, reducing maintenance costs |
