| Why These Materials Are Used in Electric Power Industry | 1. Unmatched Seawater Cooling Performance:
– Immune to chloride-induced pitting, crevice corrosion and stress corrosion cracking in seawater – Corrosion rate <0.01mm/year in flowing seawater, 1/10 of 316L stainless steel – Resists biofouling, reducing maintenance costs and improving heat transfer efficiency – Ideal for coastal power plant cooling systems and condensers 2. Superior FGD System Corrosion Resistance: – Withstands the combined attack of H₂SO₄, HCl, HF and chlorides in flue gas scrubbers – Gr.7 and Gr.12 provide exceptional crevice corrosion resistance in low-pH FGD environments – Corrosion rate <0.1mm/year vs. >5mm/year for 316L stainless steel – Eliminates frequent tube failures that cause unplanned plant shutdowns 3. Excellent Nuclear Power Performance: – ASME Section III certified for nuclear reactor auxiliary systems – Excellent resistance to boric acid and radiation-induced embrittlement – Low neutron absorption cross-section minimizes activation – Used in steam generator secondary sides and radioactive waste handling systems 4. High-Temperature Steam Resistance: – Maintains mechanical properties up to 425℃ in high-pressure steam – Resists oxidation and scaling in steam environments – Ideal for feedwater heaters and heat exchanger components 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 |
