Andre Stainless stands out as a top manufacturer and supplier of Stainless Steel 418 Bars in Singapore, Pulau Ujong. They offer high-performance materials tailored for demanding applications in aerospace, turbines, and high-temperature engineering. Also referred to as Greek Ascoloy, SS 418 is a hardenable martensitic stainless steel known for its impressive strength, oxidation resistance, and ability to withstand creep at elevated temperatures. Andre Stainless provides 418 bars in various shapes—round, square, and custom-cut—meeting aerospace-grade specifications like AMS 5616 and ASTM A565. With a focus on precision manufacturing and rigorous quality control, they guarantee long-lasting performance in high-stress, high-temperature environments.
Stainless Steel 418 Bars generally consist of 12–14% chromium, 2–3% nickel, 1.25–2.5% molybdenum, and 0.15–0.25% carbon. This alloy can be hardened through heat treatment and maintains impressive strength at temperatures reaching up to 650°C. Its mechanical properties include a tensile strength ranging from 965–1240 MPa and a yield strength of 690–965 MPa, depending on the heat treatment. SS 418 is particularly resistant to oxidation, scaling, and creep, making it ideal for turbine and rotating machinery applications. It’s magnetic and offers moderate corrosion resistance, which is perfect for aerospace and high-performance mechanical systems.
