Stainless steel tubing is a general-purpose material consisting primarily of iron, chromium (10.5% or higher), and nickel, with other elements such as molybdenum and manganese typically added for enhanced performance. It is prized for superior corrosion resistance, high strength, good machinability, and durability. With its capacity to endure high temperatures and oxidation, stainless steel tubing is commonly used in aerospace, automotive, construction, and chemical industries. Its corrosion resistance, long life, and low maintenance make it suitable for severe environments. We at Chanchai Stainless, Bangkok, Thailand, are specialists as the largest stainless steel tubing manufacturer, supplier, and exporter, providing high-quality solutions globally.

904L Tubing is an austenitic non-stabilized grade with high levels of chromium, nickel, and molybdenum, providing excellent resistance to aggressive reducing acids, notably sulfuric acid. It also exhibits very good weldability and toughness. Stainless Steel 420 Tubing is a martensitic alloy with 12–14% chromium and carbon, which features good wear resistance, high hardness, and corrosion resistance that is moderate. Mechanical properties of both tubing grades include high tensile strength, resistance to stress corrosion cracking, as well as consistent performance in higher temperatures, thus making them ideal for rigorous applications.
With outstanding corrosion resistance, Stainless Steel 904L Seamless Tubing is ideal for high-pressure applications. Typically available in sizes ranging from 1/8″ to 8″ in diameter and custom lengths, it offers uniform strength and durability without weld seams.
Welded stainless steel tubing provides good corrosion resistance and is often used in less critical applications. Sizes generally range from 1/2″ to 12″ in diameter. Its manufacturing process involves welding a flat-rolled stainless steel sheet into a tube shape.
Stainless steel heat exchanger tubes are highly corrosion-resistant and designed for thermal conductivity. Available in various sizes, typically from 1/2″ to 4″ in diameter and up to 20 feet long. Essential for efficient heat transfer in industrial processes.
Instrumentation stainless steel tubing offers excellent corrosion resistance and is used for precise control systems. Standard sizes range from 1/16″ to 1″ in diameter. It ensures reliable performance in various high-pressure and high-temperature applications.
Boiler tubes of stainless steel are known for their exceptional corrosion and high-temperature resistance. Available in sizes from 1/2″ to 4″ in diameter. Designed for use in power generation and industrial boilers to handle high-pressure steam.
Stainless steel U-tubes provide high corrosion resistance and are used in heat exchangers and condensers. Sizes usually range from 1/2″ to 4″ in diameter. They are fabricated into a U shape to fit specific thermal or fluid flow requirements.
Condenser tubes made of stainless steel are highly corrosion-resistant and used in cooling systems. Commonly available in diameters from 1/2″ to 4″ and lengths up to 20 feet. Essential for efficient heat exchange in cooling applications.
Stainless steel fin tubes offer enhanced heat transfer efficiency and corrosion resistance. Sizes range from 1/2″ to 4″ in diameter with various fin heights and thicknesses. They are used in applications with critical heat exchange efficiency, such as HVAC systems.
