Impex Tube India, a Mumbai-based leading manufacturer and supplier, excels in supplying high–performance Stainless Steel 304H Instrumentation Tubing according to international standards of quality and reliability. Enjoying a robust reputation for precision engineering and reliable service, the company offers tubing solutions designed specifically for high-temperature and high-pressure conditions. Stainless Steel 304H instrumentation tubing is designed to provide higher strength, corrosion resistance, and precise dimensional consistency, making it suitable for severe monitoring and control applications in industries like oil and gas, petrochemicals, power generation, and chemical processing.
Stainless Steel 304H Instrumentation Tubing is an austenitic stainless steel with a composition of around 18–20% chromium, 8–11% nickel, and additional carbon (0.04–0.10%) for increased high-temperature strength. This tubing possesses very good mechanical properties, such as a tensile strength of approximately 75 ksi and yield strength of approximately 30 ksi, with good elongation and ductility. The higher carbon content enhances its creep resistance and allows it to be used in applications where exposure to high temperatures is prolonged. Its accurate dimensional control and smooth surface provide reliable sealing and resistance to wear in instrumentation systems where precision is required.
