Non-Magnetic 904L Stainless Steel Flat Bar - 50x5mm Dimensions, Pharmaceutical Grade
non-magnetic 904L stainless steel flat bar (50x5mm) redefines hygiene and corrosion resistance for mission-critical pharmaceutical, biotech, and advanced medical applications. This ultra-high-purity austenitic alloy, with its unique copper and molybdenum enrichment, resists aggressive sterilants (e.g., hydrogen peroxide vapor, chlorine dioxide) while maintaining zero magnetic permeability—essential for MRI-compatible equipment and gene therapy bioreactors. Precision-rolled to 50x5mm dimensions with submicron surface finishes, it prevents microbial harborage and meets stringent FDA and EMA guidelines for direct product contact, making it the gold standard for aseptic processing and sterile manufacturing.

① Sterilant Super-Resistance
Mo/Cu synergy defends against CIP/SIP chemicals (e.g., peracetic acid, ozone), ensuring longevity in high-cycle sterilization environments.
② Absolute Non-Magnetism
Stable austenitic structure eliminates interference with sensitive bioprocessing sensors or MRI diagnostics.
③ Nano-Smooth Surfaces
Electropolishing achieves sub-0.3μm Ra finishes, preventing biofilm formation and enabling cleanroom-free assembly.
④ Pharma-Grade Compliance
Certified for USP Class VI (plasticity and biocompatibility) and EU GMP Annex 1 (aseptic manufacturing) standards.
⑤ Green Chemistry Alignment
PFAS-free passivation and carbon-neutral production align with WHO’s Safer Pharma initiatives.
⑥ Digital Traceability
Blockchain-backed QR codes provide instant access to heat treatment logs, purity reports, and ESG metrics.
Why This Product?
The 904L flat bar transcends traditional stainless steel by merging pharmaceutical-grade purity with Industry 4.0 intelligence. Its fusion of non-magnetic reliability, sterilant-proof surfaces, and digital traceability positions it as the backbone of tomorrow’s smart, sustainable life sciences infrastructure—where contamination is eradicated at the atomic level, and every batch tells a story.
