UNS S32205 material, commonly known as duplex steel 2205, is a type of stainless steel containing elements such as chromium, nickel, and molybdenum in its chemical composition.
The hot-finished seamless UNS S32205 pipes we supply are suitable for applications where dimensional precision and surface quality requirements are relatively undemanding. They are also applicable in scenarios where surface finish and mechanical properties can be easily achieved through heat treatment or machining. The cold-drawn SA789 S32205 heat exchanger tubes are designed for precision applications with smooth and aesthetically pleasing surfaces. They are stronger and harder than hot-rolled tubes, thereby enhancing resistance to deformation and are particularly suitable for applications with strict thick-wall requirements. These pipes are widely used in various mechanical components, as well as in industries such as aircraft, construction, drilling equipment, and automotive manufacturing.
