Duplex 31803 / 2205 Round Bars
20mm - 300mm
Duplex Stainless Steel 31803 / 2205 is a widely used stainless steel alloy, known for its outstanding combination of high strength, excellent resistance to corrosion, and good weldability. It is a dual-phase steel, combining austenitic and ferritic microstructures, which gives it enhanced strength and resistance to stress corrosion cracking, especially in chloride environments. This grade is highly favored in industries such as oil and gas, chemical processing, marine, and power generation due to its performance in harsh environments.
