EP Tubes (electrolytic tubes)
EP tubes has stable chemical property, high pressure-proof ability, high strength, low resistance, widely used in special gas systems,medical devices,semi-conductor and liquid crystal industry.
Mechanical Properties：can adjust HRB（75~580）figures、tensile properties and elongations.
Heat Treatment：Solution in reducing atmosphere
