The Super Duplex Steel S32750 Bars and Rods offer a well-proportioned mix of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which collectively deliver excellent corrosion resistance and strength. They achieve a high tensile strength of around 800 MPa and a yield strength of approximately 550 MPa. Owing to their outstanding toughness and notable resistance to pitting and crevice corrosion, these alloys retain superb mechanical performance even at elevated temperatures. Their distinctive dual-phase microstructure merges both austenitic and ferritic characteristics, delivering exceptional resistance to fatigue and stress corrosion cracking.

Yes, Stainless Steel 321 Rectangular Bars are suitable for welding. They provide good weldability, especially when appropriate preheating and post-weld heat treatment are applied to avoid carbide precipitation.
Stainless Steel 321 Rectangular Bars typically don't need supplementary corrosion protection coatings because of their built-in corrosion resistance. That said, in severe environments, additional coatings can be used for greater protection.
Select Stainless Steel 321 Rectangular Bars according to considerations such as strength, corrosion resistance, and the temperature demands of your application. Take into account aspects like weldability and exposure to the environment to guarantee the best performance.
Made from Super Duplex Steel S32750, these Bars and Rods are used across industries demanding outstanding strength and resistance to corrosion. They’re commonly found in offshore oil and gas platforms, chemical processing plants, desalination systems, and marine engineering projects. In addition, they serve in heat exchangers, pressure vessels, and structural parts exposed to severe conditions. Because they can withstand high pressure, temperature fluctuations, and corrosive materials, they’re ideal for pipelines, pump shafts, and fasteners. To sum up, these bars and rods provide dependable, durable performance across a broad spectrum of industrial and engineering uses.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
