Hexa Metal trading  Co.. stands as a premier supplier and manufacturer of Duplex Steel UNS S31803 Flat Bars, holding a trusted position among our clientele. Widely utilized in chemical process vessels, piping systems, heat exchangers, pulp mill digesters, bleach washers, and chip pre-steaming vessels, these flat bars offer exceptional resistance to abrasion, erosion, and cavitation erosion.

UNS S31803, also known as Duplex 2205, embodies a duplex stainless steel composition comprising austenitic and ferritic phases. Renowned for its superior corrosion resistance and high strength, this material excels in environments prone to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-containing settings. Its robust mechanical properties, including high yield strength and ductility, render it a favored choice for challenging and corrosive conditions.

Regarding corrosion resistance, Duplex UNS S31803 surpasses traditional stainless steel grades like 304 and 316, making it an ideal option for applications in the pulp and paper industry, including digesters, bleaching equipment, and stock-handling systems. While descaling may present some challenges compared to Type 304, effective methods such as alkali immersion before acid pickling and shot blasting ensure optimal performance. At Hexa Metal trading  Co.., we also offer tailored solutions, providing flat bars in made-to-order specifications to meet diverse project requirements.
