Product Description:
316 and 316L stainless steel tubes are widely regarded for their excellent corrosion resistance, particularly against chlorides and other harsh environments. These grades are extensively used in industries requiring high performance, durability, and resistance to chemical exposure.
316 Stainless Steel Tubes
Grade 316 stainless steel is an austenitic chromium-nickel stainless steel with added molybdenum, which improves corrosion resistance, particularly against chlorides and acidic environments.
Key Features
- Enhanced Corrosion Resistance: Superior to 304 stainless steel in chloride-rich and marine environments.
- High Strength and Durability: Excellent mechanical properties for structural and industrial applications.
- Temperature Resistance: Performs well in temperatures up to 870°C.
- Ease of Fabrication: Easily welded and machined.
Applications
- Marine and coastal structures
- Heat exchangers and condensers
- Pharmaceutical and chemical processing equipment
- Food and beverage industry piping
- Medical instruments and implants
316L Stainless Steel Tubes
Grade 316L is the low-carbon version of 316, offering improved weldability and resistance to intergranular corrosion.
Key Features
- Low Carbon Content: Minimizes carbide precipitation, making it ideal for welding applications.
- Excellent Corrosion Resistance: Performs exceptionally well in aggressive environments, including chloride and acidic conditions.
- High Performance in Low Temperatures: Retains toughness and strength in cryogenic applications.
- Ease of Fabrication: Similar to 316, suitable for forming and machining.
Applications
- Piping systems in chemical and pharmaceutical industries
- Offshore and marine applications
- Storage tanks and pressure vessels
- Industrial boilers and heat exchangers
- Architectural and structural applications
