Next-Generation Ferritic Stainless Steel

444 stainless steel strip redefines durability in extreme conditions, offering a unique blend of affordability and advanced corrosion resistance. Designed for industries prioritizing longevity and performance, this alloy eliminates reliance on nickel while delivering robustness comparable to premium austenitic steels.


Breakthrough Performance Metrics

  • Superior Chloride Resistance: Withstands 10,000+ hours in salt spray testing (ASTM B117).

  • High-Temperature Endurance: Stable mechanical properties up to 450°C (842°F).

  • Hydrogen Embrittlement Resistance: Critical for oil/gas and energy storage applications.

  • Low-Temperature Toughness: Maintains ductility down to -50°C (-58°F).


Advanced Chemical Profile

Element Composition (%) Role
Chromium 17.5–19.5 Forms passive oxide layer
Molybdenum 1.75–2.5 Enhances pitting resistance
Titanium 0.10–0.30 Stabilizes against sensitization
Carbon ≤0.025 Minimizes carbide precipitation
Nitrogen ≤0.035 Balances interstitial elements

Engineered for Modern Challenges

1. Smart Manufacturing Compatibility

  • Laser-cutting friendly: Low thermal expansion ensures precision in automated fabrication.

  • Electropolishing-ready: Achieves Ra ≤0.2 μm for semiconductor/medical uses.

2. Energy Sector Optimized

  • Hydrogen sulfide (H₂S) resistant for oilfield equipment.

  • Compatible with biofuel production environments.

3. Circular Economy Alignment

  • 100% recyclable with 70% lower CO₂ footprint vs. virgin 316L production.


Dimensional Flexibility

  • Thickness: 0.03 mm (ultra-fine shim stock) to 6.0 mm (structural strips)

  • Width Tolerance: ±0.1 mm for precision tooling applications

  • Surface Roughness Options:

    • Mirror finish (Ra ≤0.05 μm)

    • Satin texture (Ra 0.4–0.8 μm)

    • Micro-grooved (for enhanced adhesion in composite materials)


Industry 4.0-Ready Features

  • QR-coded batches for full digital traceability

  • AI-generated predictive maintenance data sheets

  • Compatibility with IoT-enabled thickness monitoring systems


Competitive Edge in Critical Sectors

Industry Application Performance Benefit
Aerospace Fuel cell bipolar plates 30% weight savings vs. titanium
EV Battery Thermal management foils Non-reactive with lithium electrolytes
Pharma Bioreactor liners Passes ASTM E2148 cleanability tests
5G Tech EMI shielding tapes 99% RF attenuation at 40 GHz

Certifications Beyond Compliance

  • NORSOK M-650 (offshore oil/gas)

  • FDA CFR 21 (food contact)

  • ASME BPVC Section II (pressure vessels)

  • REACH SVHC-free declaration


Value-Added Services

  • Just-in-Time Inventory: Regional warehouses in EU/NA/Asia

  • Technical Collaboration: On-site forming/welding workshops

  • Digital Twin Kits: 3D material models for simulation-driven design
