Andre Stainless stands out as a top manufacturer and supplier of Stainless Steel 409L Tubing in Pulau Ujong, Singapore. They provide cost-effective, high-performance tubing solutions that excel in heat-resistant and moderately corrosive environments. With a focus on ferritic stainless steels, Andre Stainless crafts SS 409L tubing known for its impressive weldability, thermal stability, and oxidation resistance—making it a perfect fit for automotive, HVAC, and industrial applications. Thanks to their state-of-the-art production facilities and a commitment to international quality standards, the company guarantees consistent performance even in demanding conditions.
Stainless Steel 409L Tubing is crafted from low-carbon ferritic stainless steel, which contains about 11–12% chromium and no more than 0.03% carbon. This low carbon content enhances weldability and minimizes the risk of intergranular corrosion during both fabrication and high-temperature use. These tubes boast good tensile strength (typically ranging from 380–550 MPa) and exceptional resistance to high-temperature oxidation, making them suitable for continuous operation at elevated temperatures of up to 675°C.
