Stainless Steel 321 and 321H ERW Pipe is primarily made of iron, chromium (17-19%), nickel (9-12%), and titanium (at least 5% for 321H). These alloys exhibit excellent resistance to corrosion and oxidation, high thermal stability, and excellent mechanical properties such as tensile strength and ductility The addition of titanium improves the stability of the structure against intergranular corrosion. Advantages include increased weldability, thermal fatigue resistance and suitability for aerospace, chemical processing and oil and gas industries Their long-lasting strength ensures prolonged service in harsh environments.
