Andre Stainless stands out as a premier manufacturer and supplier of Stainless Steel 347 Pipes in Pulau Ujong, Singapore. They specialize in delivering high-quality piping solutions designed for tough, high-temperature, and corrosive environments. Stainless Steel 347 is a niobium-stabilized austenitic stainless steel, known for its remarkable resistance to intergranular corrosion after welding, making it a perfect choice for applications that experience frequent heating and cooling cycles. Andre Stainless has built a reputation for sticking to international standards, precision in manufacturing, and a reliable supply chain. They cater to various industries, including chemical processing, power generation, aerospace, and refineries, ensuring that their piping systems are both durable and high-performing.
The Stainless Steel 347 Pipes crafted by Andre Stainless in Pulau Ujong, Singapore, contain about 17–20% Chromium and 9–13% Nickel, with Columbium (Niobium) added to prevent carbide precipitation. These pipes boast a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of around 40%. Their stabilization significantly boosts their resistance to high-temperature oxidation and intergranular corrosion, especially in welded conditions. Plus, the alloy maintains excellent mechanical properties even at elevated temperatures, making it ideal for challenging thermal environments.
