Chuck Metals stands out as a trusted manufacturer and supplier of Duplex Steel Square Bars in Singapore, catering to a variety of industrial needs across Pulau Ujong. These bars are celebrated for their remarkable strength, outstanding corrosion resistance, and precise dimensions, making them perfect for tough structural and mechanical applications. Crafted to meet international standards like ASTM A276 and ASTM A479, they come in various sizes and finishes tailored to specific engineering and fabrication demands.
Typically, duplex steel square bars consist of 22–25% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, all of which boost their mechanical strength and resistance to corrosion. They boast yield strengths ranging from 450–620 MPa and tensile strengths between 620–900 MPa, surpassing many standard austenitic stainless steels. The unique dual-phase ferritic-austenitic structure also offers excellent protection against stress corrosion cracking, pitting, and fatigue, particularly in environments rich in chlorides or acids.

Duplex Steel Square Bars are generally not ideal for cryogenic applications. Their performance may deteriorate at extremely low temperatures, making materials like austenitic stainless steel more suitable for such conditions.
To choose the right Duplex Steel Square Bar, consider factors such as the required strength, corrosion resistance, temperature conditions, and industry-specific demands. Ensure compatibility with your application’s mechanical and environmental requirements.
Yes, Duplex Steel Square Bars require regular inspection, especially in harsh environments. Checking for signs of corrosion, wear, or structural integrity ensures they continue performing optimally in critical applications.
These square bars find extensive use in sectors like oil & gas, chemical processing, marine, construction, and desalination. You’ll often see them in applications such as machined components, base frames, brackets, fasteners, and support structures where high strength, corrosion resistance, and geometric stability are essential. Duplex steel square bars provide a robust and cost-effective solution for long-lasting performance in challenging service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
