Stainless Steel 316 Tubes are widely recognized for their exceptional corrosion resistance, especially in chloride-rich environments. Known as a marine-grade stainless steel, 316 offers improved performance compared to 304, making it the preferred choice in industries where exposure to harsh chemicals, seawater, or extreme temperatures is common.
What is Stainless Steel 316?
Stainless Steel 316 is an austenitic alloy containing 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The addition of molybdenum significantly enhances its resistance to pitting and crevice corrosion, particularly in marine and chemical processing applications.
Key Features of Stainless Steel 316 Tubes
- Excellent Corrosion Resistance: Performs exceptionally well in acidic, alkaline, and saline environments.
- Enhanced Strength: Maintains structural integrity under high stress and elevated temperatures.
- Heat & Oxidation Resistance: Suitable for both cryogenic and high-temperature applications.
- Hygienic Properties: Smooth surface prevents bacterial accumulation, ideal for sanitary use.
- Longevity & Low Maintenance: Withstands demanding conditions while requiring minimal upkeep.
