2205 duplex stainless steel rod is a special type of stainless steel material, it is composed of ferrite and austenite two phases, with excellent corrosion resistance and high strength. This material has a wide range of applications in many industrial fields, such as chemical, oil, gas and so on.

304 stainless steel round rod is another common stainless steel material, it is mainly composed of iron, chromium and nickel. 304 stainless steel has good corrosion resistance, heat resistance and plasticity, so it is widely used in food processing, medical equipment, building decoration and other fields. Compared with 2205 duplex stainless steel, the price of 304 stainless steel is relatively low, but in some specific environments may not be as corrosion resistant as 2205 duplex stainless steel.
