Sahil Metals, based in Riyadh, Saudi Arabia, is a reputable manufacturer and supplier of corrosion-resistant stainless steel solutions designed for high-stress industrial applications. One of their standout products is the **Duplex Steel Rectangular Bar**, celebrated for its exceptional strength, outstanding corrosion resistance, and durability in harsh environments. These bars are crafted to meet international standards and are distributed across various sectors, including oil & gas, chemical, marine, and construction throughout Saudi Arabia and the GCC.
**Duplex Steel Rectangular Bars** boast a unique dual-phase microstructure of austenite and ferrite, typically found in grades like UNS S31803 or S32205. This specific composition grants them a high yield strength — nearly double that of standard austenitic stainless steels — along with remarkable resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. Additionally, these bars are known for their good weldability, formability, and fatigue strength, making them perfect for both structural and load-bearing applications.

Duplex Steel Rectangular Bars can withstand moderate to high temperatures, but their performance may degrade at temperatures above 300°C (572°F). For extreme heat, other alloys like austenitic stainless steel are preferred.
Yes, Duplex Steel Rectangular Bar are highly recyclable. Their durable composition allows them to be melted down and repurposed in various applications without significant loss of material properties.
Duplex Steel Rectangular Bars have excellent natural corrosion resistance due to their alloy composition. However, in highly aggressive environments, additional coatings or treatments may be recommended for enhanced protection.
**Rectangular Duplex Bars** are commonly utilized in the construction of frames, supports, brackets, and components that face harsh chemical or marine conditions. Their flat, solid profile makes them ideal for applications that demand both high strength and precise dimensional accuracy. Whether used in offshore platforms, desalination plants, or heavy equipment manufacturing, Duplex Steel Rectangular Bars ensure long-lasting performance, lower maintenance costs, and exceptional mechanical reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
