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.
Duplex Steel Rectangular Bars are extensively utilized in industries that demand high corrosion resistance and strength, particularly in harsh, chloride-rich environments. They are perfect for applications in offshore platforms, heat exchangers, pressure vessels, and desalination plants, thanks to their resistance to pitting and stress corrosion cracking. In construction, they are employed in structural frameworks, bridges, and support systems. Moreover, they excel in chemical and petrochemical plants, pulp and paper mills, and marine settings. Their durability and exceptional mechanical properties make them a top choice for various demanding applications.
