Andre Stainless stands out as a top-notch manufacturer and supplier of Stainless Steel 439 Tubing in Pulau Ujong, Singapore. They provide high-performance tubing solutions tailored for applications that require superior corrosion resistance and heat stability. With a strong focus on ferritic stainless steels, Andre Stainless crafts SS 439 tubing that excels in resisting oxidation, stress corrosion cracking, and high temperatures. Their tubes are produced through advanced manufacturing processes and rigorous quality control, ensuring they meet international standards. This makes them perfect for use in automotive exhaust systems, heat exchangers, and various industrial processing equipment.
Stainless Steel 439 Tubing is made from a ferritic stainless steel alloy that contains around 17–19% chromium, along with trace amounts of titanium and niobium. This carefully balanced composition enhances weldability and intergranular corrosion resistance, while also providing better oxidation resistance compared to SS 409 and improved formability over SS 430. The tubing boasts moderate tensile strength (typically between 380–450 MPa), good thermal conductivity, and remarkable resistance to scaling at temperatures up to 875°C, making it a great choice for continuous high-heat applications.

Certified by the relevant authorities, Shashank stainless offers durability, corrosion resistance and performance for a variety of applications in various fields.
This tubing is manufactured without any seams or welds, ensuring a uniform structure and high strength. It is available in a range of sizes, typically from 1/8 inch to 4 inches in diameter. Known for its excellent corrosion resistance and durability in high-temperature applications.
Produced by welding flat sheets of stainless steel into a tube shape, this option is often more cost-effective than seamless tubing. It is available in sizes ranging from 1/4 inch to 8 inches in diameter. Offers good corrosion resistance and is suitable for less demanding environments.
Designed for use in heat exchangers, this tube type features enhanced thermal conductivity and resistance to thermal cycling. Commonly available in sizes from 1/2 inch to 2 inches in diameter. It provides good corrosion resistance and thermal stability.
Ideal for precise measurement and control applications, this tubing is available in small diameters, typically from 1/16 inch to 1 inch. It offers high corrosion resistance and maintains integrity under high pressure and temperature conditions.
Used in boilers for transporting steam and other fluids, these tubes are available in sizes from 1 inch to 4 inches in diameter. They are highly resistant to oxidation and corrosion at elevated temperatures.
Shaped in a U-form, these tubes are used in applications where a flexible connection is needed, often in heat exchangers. They come in sizes from 1/2 inch to 2 inches in diameter. Known for their resistance to corrosion and ability to handle thermal expansion.
This tube type is used in condensers for heat exchange processes, typically available in sizes ranging from 1/2 inch to 2 inches in diameter. It offers high resistance to corrosion and fouling in challenging environments.
Equipped with fins to enhance heat transfer efficiency, these tubes are available in various sizes, commonly from 1 inch to 3 inches in diameter. They offer good corrosion resistance and are used in applications requiring efficient heat dissipation.
In the automotive sector, Stainless Steel 439 Tubing is widely favored, especially for exhaust systems, catalytic converter components, and mufflers, thanks to its impressive heat and corrosion resistance. It’s also commonly found in HVAC systems, commercial kitchen equipment, water heaters, and heat exchangers. The tubing’s stability during thermal cycling and its ability to resist rust in mildly corrosive environments make it ideal for both structural and fluid transfer applications. Plus, SS 439 tubing serves as a cost-effective alternative to austenitic stainless steels, providing a long service life with minimal maintenance even in moderately demanding conditions.
