S32205 is a duplex stainless steel. Its chemical composition mainly includes elements such as Cr, Ni, Mo, Ti, and Nb, and it also contains a certain amount of copper (Cu) and iron (Fe). These elements work together to endow S32205 with excellent strength, toughness and corrosion resistance, thus making it widely used in various environments.
In terms of mechanical properties, S32205 features high strength, high hardness, high toughness, good ductility and processability. Its yield strength can reach over 650MPa, with good tensile properties and the ability to withstand high pressure and temperature. In addition, the corrosion resistance of S32205 is also excellent, and it can maintain stable performance even in harsh corrosive environments.
