Knowledge

In automated production and heavy industry, choosing the correct caster material is vital to prevent bracket rust, structural fatigue, and costly downtime. HAION provides specialized stainless steel solutions for extreme industrial conditions.
I. SUS 304: The Industrial Standard
The most widely used specification for automation, electronics, and food processing lines.
   ◆ Composition: 18% Chromium, 8% Nickel (18-8 Stainless Steel).
   ◆ Properties: Non-magnetic Austenite structure with high toughness and
       superior corrosion resistance compared to zinc-plated steel.
   ◆ Applications: Food processing (freshwater washdown), cleanrooms (non-dusting),
       and automated warehousing (moist environments).
II. SUS 316: Heavy-Duty Defense
The highest standard for heavy chemical, energy, or marine environments.
    ◆ Composition: 304 base + 2-3% Molybdenum (Mo) for enhanced thermal stability.
    ◆ Properties: Exceptional resistance to chlorides and Pitting Corrosion.
    ◆ Applications: Chemical labs (strong acids/alkalis), offshore equipment (salt spray),
       and high-temperature industrial sterilization.
III. Advanced Processing & Craftsmanship
    ◆ Electropolishing: Removes surface imperfections to create a chromium-rich,
       ultra-smooth layer that resists contaminants—ideal for pharmaceutical and
       chemical lines.
    ◆ Precision Stamping: Calculating exact bracket thickness ensures high load stability
       and vibration resistance, reducing equipment wear.

IV. Industrial FAQ
     Q1: Why use HAION 304 in food processing?
            A: It prevents contamination from peeling plating.
            Its high nickel/chromium content provides superior oxidation resistance and
            an easy-to-clean surface compliant with HACCP standards.
     Q2: Is magnetism in the bracket normal?
            A: Yes. While 300-series steel is naturally non-magnetic Austenite, HAION's precision
            stamping causes localized lattice shifts into magnetic Strain-induced Martensite.
            This physical change does not affect corrosion resistance or industrial performance.
     Q3: How does SUS 316 handle offshore salt spray?
            A: The Molybdenum in SUS 316 creates a denser protective film.
            In salt spray tests, it is 3x more effective than 304, significantly reducing the risk of
            structural failure due to pitting.
     Q4: What are the designs for high-pressure washdowns?
            A: HAION casters feature reinforced swivel seals and double-ball race structures
            with high-viscosity grease. This prevents lubricant loss and mechanism seizure
            during high-pressure, alkaline cleaning.
