Product Overview
904L Stainless Steel (UNS N08904) is a super austenitic stainless steel containing:
- 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.
Key Properties
- Acid Resistance: Excellent performance in sulfuric acid (<70°C), all concentrations/temperatures of acetic acid (atmospheric pressure), and formic-acetic acid mixtures
- Chloride Resistance: Superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride media
- General Corrosion: Proven resilience in phosphoric acid and other non-oxidizing acids
Technical Characteristics
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
- High Cr-Ni-Mo-Cu content enables passivation even in reducing environments
- Demonstrated performance in specific media:
- Sulfuric acid: ≤40°C at 0-98% concentration
- Phosphoric acid: Excellent in 0-85% pure acid
- Chloride solutions: Superior pitting/crevice corrosion resistance
- Limited hydrochloric acid use (≤2% concentration) with performance exceeding conventional grades
Primary Applications
- Chemical Processing: Reactors, acid storage/transport, scrubbers
- Power Generation: Flue gas desulfurization systems
- Marine Engineering: Seawater heat exchangers/processing
- Petrochemical: Reactors, H₂S-resistant equipment
- Food/Pharma: Fermentation vessels, centrifuges, reactors
- Pulp & Paper: Chemical processing equipment
