Core product features

1. Corrosion Resistance: PREN≥35 (superior to conventional 316L stainless steel); excellent resistance to chloride-induced pitting/crevice corrosion, and erosion by nitric/phosphoric/sulfuric acids; copper-molybdenum alloying enhances stress corrosion cracking resistance.

2. Mechanical Performance: Tensile ≥650MPa, yield ≥300MPa; stable toughness and mechanical properties at -60℃to 300℃, no brittle fracture in low-temperature environments.

3. Processability: Weldable with ER385 filler; good cold/hot formability (intermediate annealing optional for complex processing to ensure dimensional stability).

Main application areas

1. Marine Engineering: Seawater cooling system filters, offshore anti-corrosion screens, marine pipeline filter elements.

2. Oil & Gas: Sour oil/gas pipeline corrosion-resistant filters, offshore drilling platform screens, oil refining equipment internal filters.

3. Chemical Industry: Nitric/phosphoric acid equipment filters, chemical reactor screening components, FGD system meshes.

4. Energy: Thermal power plant heat exchanger filters, geothermal equipment corrosion-resistant screens, nuclear power secondary circuit auxiliary filters.

5. Food & Pharmaceutical Industry: Food processing equipment corrosive cleaner filters, pharmaceutical intermediate precision filtration components.
