904L Stainless Steel (UNS N08904) - Forged Bright Bars with High Wear Resistance
Overview:
904L super austenitic stainless steel (UNS N08904/1.4539) contains:
Chromium: 14.0–18.0%
Nickel: 24.0–26.0%
Molybdenum: 4.5%
This low-carbon, high-nickel, molybdenum-enhanced alloy demonstrates exceptional passivation capability and corrosion resistance, including:
Key Properties:
904L Stainless Steel: Key Attributes
Metallurgical Structure:
Fully austenitic structure with reduced sensitivity to ferrite/alpha phase precipitation compared to conventional high-molybdenum austenitic steels.
Physical/Mechanical Properties:
Density: 8.0 g/cm³
Tensile Strength: ≥520 MPa
Elongation: ≥35%
Corrosion Resistance:
Ultra-low carbon (≤0.020%) prevents carbide precipitation during heat treatment/welding, eliminating intergranular corrosion risk
High Cr-Ni-Mo-Cu content enables passivation even in reducing environments (e.g., sulfuric/formic acids)
Demonstrated performance in specific media:
Sulfuric acid: ≤40°C at 0-98% concentration
Phosphoric acid: Excellent in 0-85% pure acid; outperforms standard stainless steels in industrial wet-process acid
Chloride solutions: Superior pitting/crevice corrosion resistance (high Ni content reduces corrosion kinetics)
Stress corrosion cracking: High resistance in chlorides (>60°C), concentrated hydroxides, and H₂S environments
Limited hydrochloric acid use (≤2% concentration) with performance exceeding conventional grades
Primary Applications:
Chemical Processing: Reactors, acid storage/transport, scrubbers (dilute sulfuric acid specialist)
Power Generation: Flue gas desulfurization systems (absorbers, dampers, spray systems)
Marine Engineering: Seawater heat exchangers/processing
Petrochemical: Reactors, H₂S-resistant equipment
Food/Pharma: Fermentation vessels (soy sauce, alcohol), centrifuges, reactors
Pulp & Paper: Chemical processing equipment
