The GB/T 14975 316L Stainless Steel Pipe is a high-quality pipe made from 316L stainless steel, which is the low-carbon variant of 316 aço inoxidável. This pipe is designed according to the GB/T 14975 standard and offers excellent resistance to corrosion, oxidation, and high temperatures. 316L stainless steel has a reduced carbon content (≤0.03%), which enhances its resistance to intergranular corrosion, particularly after welding, making it ideal for applications requiring excellent weldability and superior corrosion resistance.

With its outstanding mechanical properties and resistance to chloride-induced stress corrosion cracking, 316L stainless steel pipes are widely used in industries such as chemical processing, produtos farmacêuticos, food and beverage, and marine environments.

Unique Features of GB/T 14975 316L Stainless Steel Pipe

• Low Carbon Content: The low carbon content (≤0.03%) of 316L stainless steel minimizes carbide precipitation during welding, which enhances its resistance to intergranular corrosion and ensures the integrity of welded joints.
• Excellent Corrosion Resistance: 316L stainless steel is highly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride environments such as seawater and chemical processing.
• High-Temperature Resistance: The pipe can withstand temperatures up to 870°C (1600°F) in continuous service and up to 925°C (1700°F) in intermittent service, making it suitable for high-temperature applications.
• Superior Weldability: The low carbon content improves weldability, reducing the risk of post-weld corrosion, making 316L stainless steel an excellent choice for welded structures.
• Enhanced Durability: The pipe offers superior strength, toughness, and resistance to fatigue, ensuring long-lasting performance in a wide range of industrial applications.
