Product Overview
904L super austenitic stainless steel (UNS N08904/1.4539) is a low-carbon, high-nickel, molybdenum-enhanced alloy with 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
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%
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
- Chloride solutions: Superior pitting/crevice corrosion resistance
- 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
- Sulfuric acid: ≤40°C at 0-98% concentration
- Phosphoric acid: Excellent in 0-85% pure acid; outperforms standard stainless steels
- Chloride solutions: Superior pitting/crevice corrosion resistance
- 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
