Bulan Pipes and Tubes, Jakarta, Indonesia, is a leading producer and distributor of stainless steel piping products such as Stainless Steel 321 and 321H Welded Tubing. Renowned for providing precision-engineered solutions, Bulan is a high-temperature corrosion-resistant tubing specialist for industries needing long-term performance. Stainless Steel 321 and 321H Welded Tubing are designed to use in applications experiencing constant thermal cycling and exposure to high temperatures. These grades stabilized with titanium offer superior intergranular corrosion resistance and are a reliable option for welded tubing in industrial as well as structural use.
Stainless Steel 321 and 321H Welded Tubing are titanium stabilized austenitic stainless steels that resist carbide precipitation during welding. The grade consists of 17–19% chromium, 9–12% nickel, and titanium content (>5 times the carbon content). 321H has greater carbon (0.04–0.10%) than 321, providing greater strength and creep resistance above the temperature of 537°C. These tubes have a tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 35%. Product Name: Stainless Steel 321 and 321H Welded Tubing. Their superior mechanical strength and corrosion resistance properties make them effective for welded structures used at high temperatures.
