About Duplex Steel Round Bars
Duplex steel round bars are defined by their dual-phase microstructure, consisting of roughly equal parts austenite and ferrite. This unique composition provides exceptional mechanical strength and superior resistance to corrosion, particularly against stress corrosion cracking and pitting in chloride environments. Common grades like 2205 offer double the strength of standard austenitic steels such as 304 and 316, enabling lighter, more cost-effective fabrications. Applications span harsh environments in the oil and gas, marine, chemical processing, and wastewater management industries. Round bars are solid cylindrical rods typically made from various metals, featuring a consistent diameter throughout their length. They can be produced in different lengths and diameters, ranging from small, precise measurements to large, robust bars suitable for heavy-duty applications.
