The Stainless Steel 321 Needle Valve is made up of chromium (17–19%), nickel (9–12%), and titanium (which acts as a stabilizing element up to 0.7%), along with trace amounts of carbon, manganese, and silicon. This titanium-stabilized austenitic stainless steel is known for its impressive resistance to intergranular corrosion and oxidation, especially at high temperatures. It boasts a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%. Thanks to its excellent creep resistance, toughness, and stability, this material is perfect for high-temperature and pressure applications where consistent performance is a must.
