Key Properties
- Excellent corrosion resistance in non-oxidizing acids (sulfuric, acetic, formic, phosphoric)
- Superior pitting corrosion resistance in chloride environments
- High resistance to crevice corrosion and stress corrosion
- Density: 8.0g/cm³
- Tensile strength: ≥ 520MPa
- Elongation rate: ≥ 35%
- Melting point: 1300-1390℃
Performance Advantages
904L's low carbon content (≤0.02%) prevents carbide precipitation during heat treatment and welding, eliminating intergranular corrosion risks. The high chromium-nickel-molybdenum content with copper addition enables passivation even in reducing environments. Its high nickel content results in lower corrosion rates in active states.
Industrial Applications
- Petroleum/petrochemical equipment (reactors, heat exchangers)
- Sulfuric acid storage and transportation systems
- Power plant flue gas desulfurization systems
- Seawater treatment equipment and heat exchangers
- Pharmaceutical equipment (centrifuges, reactors)
- Food processing equipment (soy sauce tanks, cooking systems)
- Chemical processing equipment for acids and pharmaceuticals
