Stainless Steel 321 and 321H Electropolished Pipes are crafted from an austenitic stainless steel alloy that includes 17–19% chromium and 9–12% nickel, with titanium stabilization. The 321H variant features a higher carbon content (around 0.04–0.10%). These pipes deliver a tensile strength of approximately 515 MPa, a yield strength of about 205 MPa, and an elongation of around 40%. The electropolishing process boosts corrosion resistance, smooths the surface, and minimizes contamination risks. The addition of titanium helps prevent carbide precipitation during welding, ensuring structural integrity. 321H provides enhanced strength at elevated temperatures, making these pipes perfect for demanding environments that require high mechanical performance and an excellent surface finish.
