    ASTM A479 316 Stainless Steel Hex Bar 25mm Flats For Chemical Plant Equipment

    ASTM A479 316 Stainless Steel Hex Bar - 25mm Flats, Chemical Plant Equipment Material


    ASTM A479 316 stainless steel hex bar (25mm flats) is a high-performance material designed for demanding chemical processing environments. Manufactured to ASTM A479 specifications, this hex bar combines superior corrosion resistance, elevated temperature stability, and mechanical strength. The 316 grade’s addition of molybdenum (2–3%) enhances resistance to chlorides, acids, and caustic solutions, making it ideal for reactors, piping systems, and valves in chemical plants. With precision-machined 25mm flat surfaces and a uniform grain structure, it ensures reliability in aggressive media, including sulfuric acid, brine, and organic solvents.

    3. Competitive Advantages

    ① Extreme Chemical Resistance
    Molybdenum-enriched 316 stainless steel resists pitting and crevice corrosion in chloride-rich or acidic environments, outperforming 304 grades.

    ② ASTM A479 Compliance
    Guaranteed dimensional accuracy and metallurgical integrity for high-stress applications in chemical and petrochemical industries.

    ③ High-Temperature Durability
    Maintains structural stability up to 870°C, suitable for heat exchangers and exhaust systems exposed to thermal cycling.

    ④ Versatile Fabrication
    Precision hexagonal bars simplify machining into bolts, nuts, and custom fittings for complex chemical equipment.

    ⑤ Global Certifications
    NACE MR0175 compliance ensures compatibility with sour gas environments, while PED certification supports pressure equipment safety.

    ⑥ Surface Finish Options
    Customizable finishes (e.g., pickled for weldability or polished for cleanroom compatibility) meet diverse operational needs.


    4. Key Applications

    • Chemical Reactors: Hex bars for agitator shafts, reactor lids, and flange connections in acid processing units.
    • Piping Systems: Corrosion-resistant fittings, couplings, and valve stems for transporting aggressive chemicals.
    • Heat Exchangers: Tubesheets, baffle supports, and headers resistant to thermal stress and corrosive coolants.
    • Pharmaceutical Equipment: USP Class VI-compliant bars for solvent handling and sterile processing machinery.
    • Oil Refining: Pump components, distillation column internals, and scrubber systems in H₂S-containing environments.
    • Waste Treatment: Bars for sludge scraper mechanisms, filtration units, and chlorine dioxide exposure zones.

    Why Choose This Product?
    Engineered for critical chemical applications, ASTM A479 316 hex bars deliver unmatched resistance to corrosion, heat, and mechanical stress. Their precision manufacturing and compliance with global standards ensure seamless integration into equipment requiring long-term reliability in harsh operational conditions.
