Bulan Pipes and Tubes, Jakarta, Indonesia, is a well-established manufacturer and supplier of high-quality stainless steel tubing, such as Stainless Steel 321 and 321H Instrumentation Tubing. The organization specializes in providing precision-engineered products that are suitable for critical use where the product needs to be highly strong, resistant to corrosion, and stable under the influence of high temperature. Stainless Steel 321 and 321H Instrumentation Tubing are titanium-stabilized grades that offer superior resistance to intergranular corrosion and oxidation, particularly in frequent thermal cycling applications. The tubing solutions are perfect for applications in instrumentation and control systems in harsh industrial environments.
Stainless Steel 321 and 321H Instrumentation Tubing are fabricated using austenitic stainless steel that is stabilized with titanium to avoid carbide precipitation when welding. The material consists of 17–19% chromium, 9–12% nickel, and titanium, with 321H having more carbon content (0.04–0.10%) than 321, enhancing high-temperature strength and creep resistance. These tubes have mechanical properties including tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 35%. Product Name: Stainless Steel 321 and 321H Instrumentation Tubing. These grades possess high weldability, durability, and thermal fatigue resistance.
