Material Composition & Performance
The 904l stainless steel strip is distinguished by its unique alloy composition, which includes 23% chromium, 4.5% molybdenum, and 1.6% copper. These elements synergize to deliver:
- Superior Corrosion Resistance:
- Withstands sulfuric acid (up to 50% concentration at 20°C), chlorides, phosphoric acid, and seawater.
- Pitting Resistance Equivalent Number (PREN) >40, outperforming 316L (PREN ~26) and 317L (PREN ~30).
- Durability in Harsh Conditions:
- Resists stress corrosion cracking (SCC) in temperatures up to 60°C (140°F) and pressures exceeding 10 bar.
- Maintains structural integrity in acidic (pH 1–3) and saline environments, ideal for desalination plants.
- Thermal Stability:
- Operates reliably in heat exchangers and reactors at 300–400°C (572–752°F) without loss of mechanical properties.
Applications
The 904l stainless steel strip is indispensable in industries requiring longevity and reliability:
- Chemical Processing:
- Reactor linings, acid storage tanks, and piping systems handling sulfuric or phosphoric acid.
- Marine & Offshore:
- Seawater desalination equipment, ship hulls, and subsea pipeline coatings.
- Oil & Gas:
- Flue gas scrubbers, sour gas well components (NACE MR0175 compliant), and LNG processing units.
- Pharmaceutical & Food:
- Hygienic surfaces for sterile equipment, fermentation tanks, and CIP (clean-in-place) systems.
- Energy:
- Geothermal energy systems, heat exchanger plates, and nuclear waste containment.
Customization & Processing
China 904l stainless steel strip manufacturers provide tailored solutions to meet exact project requirements:
- Cold Rolling:
- Precision cold-rolled stainless steel strip roll products achieve thickness tolerances of ±0.02mm, ensuring uniformity for stamping, bending, and welding.
- Cutting Services:
- Laser Cutting: ±0.1mm precision for intricate shapes, ideal for heat exchanger plates or gaskets.
- Shear Cutting: High-speed cutting for bulk orders with straight-edge finishes.
- Surface Finishing:
- Polished Finishes: Mirror (Ra ≤0.2μm) or satin (Ra 0.4–0.8μm) surfaces for hygiene-critical applications.
- Pickling: Removes oxide layers post-welding, restoring corrosion resistance in welded joints.
- BA (Bright Annealed): Smooth, reflective surfaces for architectural or decorative uses.
- Bulk Production:
- Competitive pricing for stainless steel strip roll orders exceeding 2 tons, with custom widths (up to 1,500mm) and coil weights (500–5,000 kg).
