These are the high-quality Stainless Steel 321 and 321H Welded Tubing manufactured and supplied by Bereket Pipes in Addis Ababa, Ethiopia, for hot, high-temperature applications of various kinds. Made according to international standards, Bereket Pipes’ Stainless Steel 321 and 321H Welded Tubing is made to work in applications where oxidation, thermal stress, and intergranular corrosion resistance is critical. Providing services to petrochemical, power generation, heat treatment, and exhaust systems industries among others, the firm guarantees accurate fabrication and timely supply in the Middle East and beyond.
321 and 321H Welded Stainless Steel Tubing are titanium-stabilized austenitic stainless steel types, with 321 having superior weldability and intergranular corrosion resistance, and 321H with added carbon content (0.10% max) for increased creep and elevated temperature strength. The two types contain 9–12% nickel and 17–19% chromium. The tubing has tensile strength of 515–750 MPa and yield strength of approximately 205 MPa. Welded fabrication enables economical manufacturing with sound structural integrity and corrosion resistance through 900°C temperatures.
