The GB/T 14975 304L Stainless Steel Pipe is a high-quality pipe made from 304L stainless steel, which is a low-carbon version of 304 aço inoxidável. Manufactured according to the GB/T 14975 padrão, this pipe offers superior resistance to corrosion, oxidation, and high temperatures. The low carbon content (≤0.03%) in 304L reduces the risk of carbide precipitation during welding, making it ideal for applications that require excellent weldability and enhanced resistance to intergranular corrosion.

This pipe is widely used across various industries, including chemical processing, food and beverage, pharmaceutical, e construção, due to its exceptional strength, formability, and resistance to corrosion. It is particularly suited for environments where welds are common and high resistance to corrosion is necessary.

Unique Features of GB/T 14975 304L Stainless Steel Pipe

• Low Carbon Content: With a carbon content of ≤0.03%, 304L stainless steel minimizes carbide precipitation during welding, which improves the pipe’s resistance to intergranular corrosion.
• Excellent Corrosion Resistance: 304L stainless steel offers exceptional resistance to corrosion in a variety of environments, including acidic, alkaline, and chloride-rich settings, making it ideal for chemical and marine industries.
• High-Temperature Resistance: The pipe can withstand high 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 enhances weldability, reducing the risk of post-weld corrosion and ensuring the integrity of welded joints.
• Non-Reactive: 304L stainless steel is non-reactive and does not leach harmful substances, making it ideal for sanitary applications in the food and pharmaceutical industries.
