The composition of Stainless Steel 321 Needle Valves includes chromium (17–19%), nickel (9–12%), and titanium as a stabilizer, along with trace elements. This blend provides exceptional resistance to high-temperature corrosion and stress corrosion cracking. They have a tensile strength of about 515–620 MPa and a yield strength of around 205–275 MPa, along with remarkable toughness and ductility. The titanium addition helps stabilize the alloy against sensitization during welding and exposure to high temperatures, making these valves perfect for critical applications in instrumentation and process systems.
